With the new Power Mill end mill series, HAIMER can also provide its tool holders with a universal solid end milling range for machining of steel, stainless steel and cast iron materials.

All Power Mill endmills are fine balanced and by default equipped with the known Safe-Lock pull-out protection from 6 mm shank diameter onwards. The Power Mill series is based on a pure high performance solid carbide combined with the most modern coating technology.

The different innovative precision geometries are now available as 3, 4 and 5 flute cutters in different cutting lengths. Furthermore, different cutting edge designs (sharp, chamfer or radius) can be selected depending on the workpiece requirements. In addition, a roughing geometry based on the new cordprofile for machines with less power and applications with difficult chip removal, is available.

The spindle speed of modern machine tools have increased on a continuous basis in the last few years in order to achieve higher cutting volumes and machine in a profitable manner. The increases have also raised the demands for the tools and holders used, because the higher spindle speeds make the effects of imbalance increasingly more noticeable. The consequences are vibrations, bad surface finish and shorter tool life.

Only the high-precision balancing of tools and tool holders can make the complete capacity of the machines tool with regards to speed, cutting volume and produced surface finish accessible. Because balancing provides for fewer vibrations. It reduces wear of the spindle and tool, reduces the downtimes and increases process security.

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.

For years, HAIMER has been leading in the development of inductive shrink technology for tool holders. Many patents, mainly in the area of inductive coils, are visible proof for innovation and progress.

The patented coil technology in conjunction with the intelligent power electronics form the core of HAIMER shrink fit technology.

Perfectly coordinated assembly groups and electronic components make sure that only the clamping area of the chuck is heated in the shrinking process.

This reduces the shrinking and cooling cycle to a minimum.

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.

The spectrum of the machines ranges from the beginner model, Power Clamp Basic, to the high-end device Power Clamp Premium Plus. Use the world’s largest range of products of shrink fit machines and coils.

High performance machining (HPM) of difficult to machine materials places enormous demands on tool holding. Therefore, the order of the day always includes the fact that a slow micro-creeping movement takes place and the tool is pulled out of the chuck due to the high degree of axial forces.

Even frictional clamping methods with extremely high clamping forces can often not prevent micro-creeping. Thus, high quality work pieces become scrap.

As a consequence, the cutting data on the machine tool is often reduced. Therefore the maximum performance limits of the machine and tools is not completely taken advantage of; machining is ineffective.

The Safe-Lock System offers help
In the Safe-Lock System, special drive keys in the chuck and grooves in the tool shank prevent the milling cutter from spinning during extreme machining or that it is pulled out of the chuck.

In addition to the frictional clamping forces of the particular clamping system, the tool is held using positive locking in the tool holder through the constructive design of the Safe-Lock System.

The combination of pull-out protection and best runout accuracy lead to a low vibration and as a result very efficient machining.

Due to the increased cutting depths and feeds, the metal removal rate can be increased by up to 100%, and to a similar degree tool wear decreases due to the excellent runout characteristics.

On the safe side with Safe-Lock:
