The importance of the tool holder is still understated, especially when it comes to roughing and heavy dutymachining. Metal removal rates in these types of processes are absolutely crucial for the productivity of the machining operation. By using special shrink fit chucks with drive pins and spiral grooves in the tool shank it is now possible to performhigh-feed full slotting of up to 2 x D (50 mm) or more indifficult to machine materials. Application studies conducted by the machine tool manufacturer Heller have proven the effect of the HAIMER Safe-Lock system.

Especially within the aerospace, energy and mechanical engineering sector, production managers have to bridge the gap between economic efficiency and high process reliability when working with materials that are difficult to machine. Fortunately there is peace of mind in knowing that the machine technology innovations continue to develop to meet the ongoing demands of manufacturing.Heller machine tools is known as a source of inspiration for these kinds of innovations. The company, located in Nuertingen, Germany, is known for its high quality 4 and 5-axis CNC machining centres, CNC mill/turning centres, CNC machines for crankshaft and camshaft machining as well as flexible manufacturing systems. Customers value their availability of products and their competency in managing special processing demands. Both qualities stem from Heller’s in-house manufacturing, which relies on closer collaboration with customers, suppliers and researchinstitutes to remain on the forefront of innovation.

Roughing is a highly promising process

Werner Kirsten, who is working in the Technology Development Department at Heller and is responsible for the area of “difficult to machine materials“, explains: “our service includes optimizing the machining processes together with our customers and suppliers. To support such services with practical trials, our Technology Center is equipped with a variety of machines”. In most cases the aim is to increase the productivity without compromising the process reliability. Technologist Kirsten adds, “We often achieve this aim with an optimized roughing operation which ultimately results in a reduced finishing process. By maintaining the same technological values, but shortening the finishing depth of cut by 50%, the overall machining time is reduced to half. However, this requires process reliable and controllable systems during roughing.”

In this regard,all machining components in the process chain have to be considered in order to improve productivity. The machine tool is the most evident component of the machining process, however the tool, the tool holding system, the coolant supply and other elements are also essential for a successful operation. “In the end the weakest link of the process chain limits the success,” Werner Kirsten emphasizes. In his opinion most machine shops don’t pay attention to the tool holder even though it is especially significant for high performance cutting. “Many of the trials which we carried out during the last few years have proven this point”, Werner Kirsten explains. We realized that the tool holder hasan incredible influence on the machining process. In the case of reinforced shrink fit chucks, for example, the vibration node is closer to the bearing point (due to the larger mass). The result is a smoother machining process with less vibration and a better surface finish quality while using the same tool, machine, process parameters and fixturing technology.”

Tool holding – an important factorfor productivity

By selecting the right tool holder you can even achieve good productivity and surface quality results using basic standard cutting tools. Werner Kirsten refers to comparative tests with basic four-edge cutting tools without an inner coolant supply. As an alternative to a standard shrink fit chuck he selected a HAIMER Power Shrink Chuck with Cool Flash which ensures that the coolant is transported directly to the cutting edges. “Compared to using a normal shrink fit chuck and externalcoolant, we were able to achieve significantly better results.”

When a group of representatives from the aerospace industry, the Technical University of Dortmund and Technical University of Hamburg-Harburg visited Heller,an especially extensivemilling application study was conducted in Titanium Ti-6AI-4V.

Gaining new insights from difficult cases

The available machining center was a four axis Heller H 5000 with a gear unit and HSK-A100 spindle, which yields torques up to 2.290 Nm. In order to demonstrate the machining potential, different 25mm diameter end mills were used to mill full slots into a titanium plate. To simulate holder conditions used in the aerospace industry, the tools were clamped into reinforced shrink fit chucks. At an axial cutting depth of0.5 to 1.0x D the machining process was found to be very reliable. Since the spindle was not running at full capacity, the trial participants agreed to increase full slottingdepth to 2 x D. Werner Kirsten explains: “Under these conditions the tool pulled out of the shrink fit chuck during the machining operation, creating a slot closer to 2.5xD as it progressed through the part. Towards the end of the slot the tool finally broke as a result of increased cutting forces.”

The milling specialists all agreed that the clamping force of the chuck was the limiting factor in this process. As soon as the axial pressure and process related vibrations are too high the tool moves out of the chuck and further into the workpiece. At the same time the cutting pressure increases such thatin the end the tool breaks and the workpiece is irreversibly damaged.

Reasons and possible countermeasures were discussed intensively. In the end, Werner Kirsten developed the idea that the tools are forced to navigate towards the spindle when the holding forces are exceeded. This is how he ultimately noticed the patented HAIMER Safe-Lock system which in addition to frictional clamping forces, has the same helix pattern as the tool. Theoretically, he realized that even if the tool got loose while using Safe Lock, it would be pulled into the holder through the helical drive keys and not into the part. A movement that can be easily prevented through the use of length presetting screws.

Prevent tool pull-out

Werner Kirsten got in contact with HAIMER, the European market leader for tool holding technology, in order to test the Safe-Locksystem: “we wanted to know if our ideas could be put into practice using the HAIMER system in an even less forgiving environment.” The Heller technology developer repeated the described trial,with a few major changes. HAIMER Safe-Lock grooves were subsequently added on similar solid carbide tools, but the application would be run again with a reduced spindle taper interface (HSK 63 instead of HSK 100), with a less rigid 5-axis gear driven spindle and a less stable diagonally fixtured workpiece.

The result: Despite these additional limiting factors, the tool was able to process a full slot of 2 x D = 50mm with complete process reliability. Werner Kirsten says: “this way we were able to indirectly prove that Safe-Lock works and that the shrinking technology has even more potential with HSK-A100, especially on 5-axis machining centers withgear spindles.” Afterwards this samplemachining on Ti-6AI-4V was carried out various times, including during the Airshow in Farnborough, whereby it was proven that the previous limit of 1 x D = 25 mm full slotting in titanium could be doubled with the use of Safe-Lock.

Kirsten summarizes the results as follows: “For roughing operations this is a reliable process. Therefore I consider the HAIMER Safe-Lock system a practical, easy to handle and process reliable addition to the shrinking technology which we already utilize, especially in connection with standardized tools of other manufactures.”

A number of tool manufacturers are offering Safe-Lock products

From the onset of its creation, HAIMER recognized the incredible potential of the Safe-Lock system, which is why the company created a licensing program to give innovative tool manufacturers the ability to integrate the patented pull-out protection system into their tools. The result of their

vision to create a more open system has been a tremendous success, with leading cutting tool manufacturers having now signed licensing agreements, including Walter, Widia, SandvikCoromant, Seco Tools, Sumitomo, Kennametal, Helical, Emuge Franken, Data Flute, Niagara, OSG,SGS Tools and recently Mapal.

Through the steady increase of Safe-Lock tooling in the market via Haimer and its licensed partners, the system has become the new standard for heavy machining and roughing. In fact, the popularity and simplicity of Safe-Lock is such that it is also replacing the old Weldon clamping system, particularly when new milling strate-gies such as trochoidal (dynamic) milling are involved. President of HAIMER Group Andreas Haimer explains: “With our Safe-Lock system we found a solution that combines a high runout accuracy with 100% pullout protection. The system has es-tablished itself successfully as a standard in the aerospace industry and generally speaking for roughing and heavy duty machining. And now more and more compa-nies that make use of the trochoidal (dynamic) milling strategy are also making the switch to Safe-Lock, and for a good reason.”

During trochoidal milling operations, where the cutting speed and axial depth of cut can be increased through software support, productivity is significantly improved. However, the increased cutter engagement and cutting forces that result from the higher cutting performance create a situation where tool-pullout can occur very easily. Prior to Safe-Lock, this problem was prevented with Weldon shanks and chucks.However customer had to sacrifice speed and accuracy due to the nature of this clamping system. A shrink fit chuck with Safe-Lock offers the same safety as the Weldon system, but provides the additional advantage of accuracy and balance. The ideal balancing and runout characteristics of the shrinking technology in combi-nation with the clamping safety of the Safe-Lock system permit greater productivity achieve through fasterpermissiblespeedsand increased tool lif e all with complete tool security assurance

German based high precision products solution providers for metal cutting, HAIMER will be giving live demonstration of its latest tool holding, clamping and balancing machines at the India’s largest die mould exhibition, Die Mould India 2016. The company is going to highlight its revolutionary tool holding devices, power clamp range of shrinking technologies and balancing machines along with other technologies.

The company will showcase:

Tool Holders
HAIMER offers the right clamping technology for every industry, application and typical machining operation. Take advantage of the innovative solutions from the technology leader for tool holders.

Shrinking Technology
For years, HAIMER has been the leading developer of inductive shrink fit technology for tool holders. Rely on our broad experience and use the world’s largest range of shrink fit equipment and coils. With the Power Clamp range, HAIMER provides its shrink-fit chucks with a comprehensive and well thought out range of devices of inductive shrink fit machines. By doing so, you profit from the fact that HAIMER perfectly coordinates shrink fit machines and chucks in its own production.

Balancing Machine
With the Tool Dynamic series HAIMER offers a universal machine concept for balancing tool holders, grinding wheels and other rotors. Increase your productivity with less unbalance in your production. With the Tool Dynamic balancing machine series, HAIMER offers a comprehensive solution for the balancing of tool holders, grinding wheels and big rotors with diameters up to 800 mm. Starting from the table and complementary machine TD 1002 to the automatic balancing machine TD 2010 Automatic, HAIMER has for every need the suitable balancing machine.

After a record year in 2014 with a 20% sales increase the HAIMER Group can also announce a double-digit growth for 2015. The newest shrinking and balancing technology from the European market leader for tool holding technology played a big part in this successful growth. The newly developed carbide milling systems offer a very promising future and are being met with great interest in the area of high performance machining.

In comparison to 2014, the HAIMER Group reported a sales increase of 10.5% for 2015. Andreas Haimer, who amongst other things, is responsible for the international business, explains that “especially the subsidiaries developed very well and within the last years we often noticed that being present in other countries increases the turnover. This way we can offer our dealers on-site support and present ourselves as a global partner to our Key Accounts.” In 2015 HAIMER UK was founded in Manchester and for 2016 establishing a French subsidiary is planned. Furthermore, the new Application Center at the Haimer North America headquarters will celebrate its opening in the middle of May. In the future the biggest subsidiary located near Chicago, can offer application support, live cutting tests, and a high-quality regrinding service for all HAIMER carbide tools.

In each country the shrinking technology has proven to be a growth driver. Especially Safe-Lock, the patented pullout protection system for end-mills, continues to grow rapidly. Due to its constantly increasing distribution, Safe-Lock is said to be the new standard for heavy machining and roughing operations. The system combines highest runout with process reliability and pullout protection and “the results are outstanding” as Andreas Haimer explains. “Even when it comes to new milling strategies such as trochoidal machining, Safe-Lock replaces the outdated Weldon clamping system.”

The Safe-Lock system has evolved from a special solution to an industry standard: Leading tool manufacturers such as Walter, Widia, Sandvik Coromant, Seco Tool, Sumitomo, Kennametal and others have contributed to this fact by acquiring a license and adding more and more Safe-Lock tools to their product portfolio. And the numbers keep increasing. Since 2015 the OSG Group, Japanese market leader in the area of solid carbide end-mills, is offering their high-performance solid carbide cutters with the HAIMER Safe-Lock system. Also another leading American tool manufacturer, SGS Solid Carbide Tools, decided to start selling Safe-Lock tools within the last year. Most recently, in January 2016, Melin Tools and APN, the former is an American tool manufacturer and the latter a French tool manufacturer, got licensed for Safe-Lock. Andreas Haimer emphasizes the global availability of Safe-Lock: “With their range of milling tools our partners already dominate the majority of the global milling tool market. The annual sales of Safe-Lock cutting tools make up for double-digit million dollar turnover and there is even more potential.”

Solid carbide tools with HAIMER quality
Within the last months the Power Mill product portfolio was further expanded. Aluminum geometries and ball nose cutters were added to the selection of carbide milling tools. Furthermore, at EMO 2015 in Milano the Basic Mill, a round shank version and entry level cutter with universal use, was introduced.
With the Duo-Lock system HAIMER is providing a modular carbide milling system which shows an unheard of level of stability. Similar to the Safe-Lock system, Duo-Lock is offered to other tool manufacturers via licensing. But Haimer itself also has a large and ever expanding standard portfolio of Monobloc tool holders, milling heads and extensions with a Duo-Lock interface. The system runout of modular tools is better than 5 µm and has a Z-accuracy of 10 µm, which makes expensive presetting processes or set ups unnecessary.

Exhibitions and the first Open House event
In 2016 everyone who is interested will have the opportunity to experience firsthand, shrinking and balancing machines, tool holders and tools during one of our many global exhibitions. In Germany, HAIMER is going to participate in such events as Metav, Grindtec, AMB and many others. Furthermore, the company is hosting its first Open House event during the 26th and 30th of April. It offers top-class lectures and a sub-exhibitor program in the area of machine tools and tools, as well as guided tours throughout the Haimer facility.

The Tool Dynamic Automatic from HAIMER is a truly universal, vertical 4-axis CNC-based balancing machine with a Siemens 840 D sl control. Thanks to this innovation, machine users can measure the unbalance of their tools, locate and remove it by drilling or milling in one or two planes. Operators no longer need to go to a separate drilling machine. Thanks to highly accurate clamping and precise metal removal, excellent balance can be achieved. This innovative development of the time-tested HAIMER balancing systems has led to further increases in efficiency for tool balancing.

To bring efficient tool balancing to a completely new level, a flexible solution was sought to automate the manual process of loading and unloading tool holders. In addition to automation, further emphasis was placed how to avoid the issue of bulky safety guards, commonly associated with robotic equipment.

The sensitive lightweight robot LBR iiwa (intelligent industrial work assistant) from Kuka takes on this task. The LBR iiwa moves tools holders waiting in queue and inserts them in the balancing adapter of the TD Automatic, which automatically clamps the rotor with highest precision. After measuring and correction of unbalance in less than 1 minute the KUKA flexFELLOW removes the chuck from the balancing adapter again and places it back in its original docking position.

Due to the KUKA flexFELLOW ease of mobility, other Haimer balancing machines can be automated in less than 10 minutes, and productivity can realized for mid-sized and large batches.

In the complete loading and unloading process of the balancing machine, the machine operator can stay close to the KUKA flexFELLOW robot, and if necessary remove parts or make adjustments, without fear of injury. This is made possible by touch-sensitive sensors in the robot that stop movement immediately upon any disruption. These new touch-sensitive features make it possible to permanently eliminate bulky safety guards, thereby reducing space requirements. The KUKA flexFELLOW makes it possible to sustain a fully automated and autonomous work cell, ideally suited for Industry 4.0.

By recording process data and analyzing this data afterwards (which was previously only possible to a limited extent as all data was manually recorded) there now exists the possibility to optimize processes to a completely new level.

Due to the positive form and frictional clamping system made by HAIMER, MTU Aero Engines in Munich was able to increase the reliability in the process of machining difficult-to-cut materials while also decreasing their processing times.

MTU Aero Engines is Germany’s leading engine manufacturer and an established global player in the industry. The company engages in the design, development, manufacturing and support of commercial and military aircraft engines in all thrust and power categories and stationary gas turbines. Due to HAIMER‘s patented Safe-Lockpull out protection system, MTU was able to optimize their machining process regarding the production of structural frames and castings.

Jet engines are high-tech products. In their production, innovative technologies and processes are used. To keep current technologically, MTU develops innovative manufacturing strategies, and if necessary obtains additional external expertise. So was the case when they contacted HAIMER, the tool holding specialists from Igenhausen, Germany, to help optimize the demanding machining process of manufacturing frames and castings.

Difficult-to-machine materials, high-quality components and the high degree of automation at MTU require an absolutely smooth and reliable machining process to maintain the highest levels of quality. In order to ensure this consistency and to control the high axial cutting forces during machining, MTU decided to implement the Safe-Lock pull out protection system by HAIMER.

In the HAIMER Safe-Lock system, special drive keys in the tool holder and grooves in the tool shank prevent the cutting tool from spinning during extreme machining, thus preventing tool pull out from the chuck. In addition to the frictional clamping forces of the selected clamping system, the cutting tool is held using positive form locking in the tool holder through the constructive design of the Safe-Lock system.

Alexander Steurer, Senior Manager NC-Programming Stator Components at MTU Aero Engines AG in Munich, explains the decision for the HAIMER system: “Through the introduction of Safe-Lock and the shrinking technology from HAIMER, we can guarantee process reliability even with milling challenging high temperature materials. This is a prerequisite to guarantee smooth processing during manufacturing of frames and castings, given our high degree of automation.“

The combination of pull-out protection and highest concentricity of the Safe-Lock system leads to low vibration and as a result, a very stable machining process. Due to the increased cutting depths and feeds, the metal removal rate can be increased significantly. And thanks to the improved runout accuracy of HAIMER shrink fit chucks, tool life is improved by up to 50%.

The benefits of less than 3 µm runout, that the symmetrical Safe-Lock design provides, coupled with optimum balance and the possibility for easy length presetting were substantial reasons for MTU to switch to the HAIMER system instead of continuing to use Whistle Notch or Weldon tooling systems. While these other systems do in fact prevent tool pull out, both are unsymmetrical by design, hence providing insufficient runout and balance accuracy.

Through the use of a set screw the cutting tool is wedged against the opposite wall of the clamping bore. The holder pushes the cutting tool off center and thereby leads to excessive amounts of runout. Any such design also allows for significant radial play between the tool shank and the bore itself. That way the aforementioned holders actually push the cutting tool off center, thereby inducing excessive amounts of runout. Hans Drahtmüller, Line Manager Machining Stator Components at MTU in Munich, explains the resulting problems: “Due to the deteriorated runout, the tool life could not be fully realized. As a result, the tools with a Weldon flat had to be exchanged early. With Safe-Lock regrinding could be automated due to the cylindrical form of the system, as the cutting tools no longer have to be inserted manually into the grinding machine compared to Weldon flat tooling. This saves tool costs!“

Easy and quick tool change

In addition to productivity improvements in the machining process, time is also saved outside of the machine via extremely fast and easy tool changes. HAIMER Power Clamp Premium NG, the high end shrink fit machine MTU is using currently, offers an ergonomic working space, perfect handling and linear guided cooling bodies with temperature monitoring for maximum safety. Presetting the tool length to exactly 0.02 mm (e.g. for sister tools) can optionally be integrated into this machine. The intelligent New Generation (NG) coil is adjustable. With one turn, you can set the coil to the size of the shrink fit chuck both in length and diameter. This new system obsoletes the former interchangeable ferrite stop disks, which were always at risk of breaking during change overs. Thanks to the multiple patented HAIMER technology, the shrink fit chuck is only heated in areas where it is necessary. This way the process of both heating and cooling the tool holders is much faster. During the cooling process different sized cooling bodies shorten the cooling time and create a gentle, even and clean cooling effect. The cooling bodies ride on linear guides, so that the cutting edges are always protected from collision with the cooling body.

True to the slogan “make good things even better”, HAIMER developed the Cool Flash system based on the existing Cool Jet system for shrink fit holders in order to guarantee an optimal coolant outlet even at high speeds

Functional principle

In the Cool Flash system – similar to the Cool Jet system – coolant bores are made in the tool holder with which the coolant is transported up to the face surface of the chuck. There is a pad placed on the face surface of the Cool Flash chuck which leaves a narrow circular gap leading up to the tool. The coolant is collected in this chamber, creates high pressure and is distributed over the entire circumference of the tool shank. It flows out of this small reservoir like a closed housing directly along the tool shank. At the end of the shank area, the coolant is pressed into the T-slots, rinses them free and even at the highest speeds it reaches the cutting edges directly, without sputtering, where it can deploy its cooling effect.

Easy handling

Compared with the state of the art, the new HAIMER Cool Flash system offers the decisive advantage that no additional sleeves or separate holders become necessary for optimal cooling, which would otherwise entail greater effort during the shrink fit process. The HAIMER shrink fit chucks can also be shrinked and unshrinked “normally” with the Cool Flash option. Furthermore, stability, rigidity and interference contour of the original

HAIMER holder remain unchanged.

With a booth size of 338 square meters, Haimer GmbH is more present than ever at this year’s EMO 2015 show in Milano (hall 6, booth L08/M03): for Italy and the European market. Its Italian subsidiary HAIMER Italia Srl, located close to Milano in Bernareggio, was founded in 2014 and has already been able to achieve considerable success in sales, is now looking forward to EMO Milano.

Next to some new innovations, the European market leader in the area of tool holding technology will also present its already established and wide-ranged product portfolio, consisting of highly precise tool holders and practical special machines

The visitors will be able to experience all HAIMER shrinking and balancing machines live. This includes the high-end-version Tool Dynamic Automatic, a CNC-based machine for automatic balancing, as well as TD 800, a machine suited for balancing big rotors and grinding wheels. The Cool Flash system will be one of the booth’s highlights, as within the last four years it has attracted more and more customers. Cool Flash can be optionally applied to HAIMER Shrink Fit Chucks and it ensures that even at a high rpm the coolant is transported directly to the cutting edge.

For many years now the HAIMER Safe-Lock system, a patented pull out protection for endmills, has proven to be a very successful invention. Due to its growing spread Safe-Lock is considered to be the new standard for roughing and heavy machining. Also for new milling strategies such as trochoidal applications, Safe-Lock is about to replace the outdated Weldon clamping system. Safe-Lock brings together the highest runout accuracy, process reliability and pullout protection. Leading tool manufactures such as Walter Tools, Widia, Sandvik Coromant, Seco Tools, Sumitomo, Kennametal, Helical, Emuge Franken, Data Flute and Niagara have already decided for this system and became license partners. And the numbers are increasing. Not long ago the OSG Group, the Japanese market leader in the area of solid carbide endmills, has started offering their high performance solid carbide endmills together with the HAIMER Safe-Lock system.

Another highlight will surely be the final version of Duo-Lock, a modular interface for solid carbide milling heads. The announcement of the Duo -Lock partnership between HAIMER and Kennametal in 2014 and the presentation of this system were followed by elaborate in-house-tests for each diameter and external field trials with customers from different industries. Just like the Safe-Lock system, the patented and trademark protected Duo-Lock is offered to other tool manufactures via licensing model in order to establish a compatible high performance standard. At the end of this year the Duo Lock products will be available on stock.

Furthermore, HAIMER customers can count on new and innovative products in the area of heavy duty machining. A new Heavy Duty Collet Chuck is going to celebrate its world premiere and at the same time, the new HAIMER solid carbide tool portfolio is going to be extended by a number of geometries and designs. In order to provide an Italian flair at EMO Milano, HAIMER is going to machine aluminum Espresso cups on DMG MORI HSC 30 – of course with the use of HAIMER Power Mill tools and HAIMER shrink fit holders.

Haimer GmbH, Germany has now developed a special balancing arbours for tools with cylindrical boreholes. With this, users can also balance their grinding wheels, cutter heads, planing heads and other tools unbalance on Tool Dynamic balancing machine.

Up to now, one could balance primarily various tool holders (HSK or taper cone), as well as the tools with cylindrical shafts clamped into them, in the Tool Dynamic by HAIMER. However, even grinding wheels and large cutting heads are sometimes run at high speeds, and cannot do without balancing beforehand. This is why Haimer now offers balancing Arbours in a variety of clamping sizes.

Particularly in Finish Grinding process, Wheels run at speeds of up to 30,000 rpm and thus needs to be balanced in order to prevent damage to the spindle. In comparison to conventional balancing scales, whose results depended largely on the skill of the user, balancing on the Tool Dynamic machine provides considerably better and – most importantly – consistently good results.

HAIMER has developed the Cool Flash system based on the existing Cool Jet system for shrink fit holders in order to guarantee an optimal coolant outlet even at high speeds.
