Ural-instrument-Pumori company (Perm city, Pumori Urals Machine-building Corporation member company) has produced “Centre UiP VF400”, the first Russian-Indian machining centre.  Machine assembly marked a new stage of cooperation with Ace Manufacturing Systems (AMS), Indian machine-tool building company. AMS is a member of ACE Micromatic Group and is the largest manufacturer of horizontal and vertical CNC machining centres in India. The company constantly develops a range of the supplied equipment expanding supplies both to domestic and export markets. The basic countries of export are Brazil, Egypt, Germany, Spain, Great Britain, Japan and USA, more than 200 CNC machines were supplied to these countries.

Cooperation of Ural-instrument-Pumori with AMS was started in 2007 with the supply of CNC machining centers to Russia. Since that time these machining centers have proven to be high-quality and reliable equipment, providing customers with cost efficient and at the same time effective solutions for specific production targets. In December 2013 an agreement on assembly of the machines in the territory of the Perm district was signed.   Under this agreement AMS company supplied a machine frame, and all the necessary machine units were manufactured in the territory of the Perm district. High quality requirements caused a necessity of careful selection of a manufacturer and suppliers.  Not only high quality geometrical arrangement with an exact conformity to drawings, but also an outside view was important. The machine manufactured by Ural-instrument-Pumori passed all the necessary tests and meets all the requirements for the equipment, manufactured in the territory of Russian Federation, what is confirmed by the certificate of conformance.

Production of the machines in Russia with the usage of component parts produced in Russia made it possible to reduce production cost thus provoking a competition for the imported equipment, what is important in the light of the present situation. In 2015 it is planned to manufacture a CNC machining center— “Centre UiP VF450/100”, as well as another models in the total amount of not less than 20 pieces.  Going forward it is planned to create an assembly center in Perm. Implementation of this project is possible only in case of production localization, which implies creation of new workplaces in Perm district and placement of orders for component parts produced by the local manufacturers.

Doosan Machine Tools recently launched its new VCF 850 Series of column moving machining centers, which can be used to perform a wide range of machining works using 3 to 5 axes integrated into a single machining center.

Designed with embedded and top-mounted type rotary tables and a tilting head, the new VCF 850 Series can process work pieces in any of the 3-, 4- and 5-axes modes. Furthermore, the series boasts a wide machining region with its compact size of 3795 mm (L) X 5440 mm (W), thanks to the incorporation of a movingcolumn design.

Enhanced precision and productivity
It is generally accepted that most machining centers fall into either the 3-axes or 5-axes category. The VCF 850 Series, however, is designed to be customized to perform 3-, 4- or 5-axes machining works with one single machine. The tilting head of the B axis, which supports 4-axes cutting, employs a built-in type of spindle to minimize vibration and noise while delivering excellent reliability and accuracy. The maximum
speed and torque of the spindle are 12000 rpm and 204 N·m, respectively. The oil cooler – with control accuracy of 0.1 degrees – and the dual-contact tooling system reduce vibration during cutting, increase tools’ service life, decrease surface roughness, and improve machine productivity.

Application
The rotary table, which can be applied to A or C axis direction to support 5-axes machining, is offered in both factory-installed and user-installation options, widening the customer’s range of choice according to the machining requirements.

Compact size
The ‘column-moving-type’ VCF 850 Series offers the following advantages compared to table-moving types: First, though smaller than table-moving-type machines of the same class, the VCF 850 Series provides a wider cutting range of 3 m in the X axis. This is a very important advantage that enables a significant saving on investment in the expansion of shop space and machinery. Second, the lightweight head can carry out cutting operations with up to 3500 kg of heavy work fixed on the table. As such, the series supports the cutting of heavier work pieces with a greater degree of accuracy than table-moving-type machines, and delivers high-quality machining.

Easy and convenient operation
Offering maximized user convenience as well as greatly enhanced quality and performance, the VCF 850 Series allows the operation panel to travel along the X axis, and provides a maximum main door opening length of 3220 mm considering the operator’s working movement. Along with the standard drum type tool magazine capable of holding up to 30 tools, a chain-type tool magazine with a maximum capacity of 60 tools is also available as an option. The inclusion of a separate pickup magazine capable of holding 5 long, large tools (up to 80 mm in length & 130 mm in tool diameter), and a machine structure that uses a crane for loading/unloading heavy work pieces, reveal the extent to which Doosan has focused on ergonomic design and work efficiency.

By combining various machining capabilities in one single machine, the VCF 850 Series’ largest-of-the-class X axis travel distance enables multi-vise chucking to maximize machine productivity. A partition is provided within the machining area to separate the cutting area and the set-up area, thereby minimizing idling time. The feed rate of each axis is a rapid 40 m/min, while the tool changeover time is a mere 1.5 sec. In addition, turning and simultaneous 4/5-axes cutting, which until now have mainly been performed on turning centers, can now be carried out using the VCF 850 Series’ indexing table and rotary table. Ultimately, the VCF 850 Series’ impressive multi-functional, multi-purpose features will provide customers with a great opportunity to reduce their equipment and labor costs.

At the 2014 SEMA Show, taking place Nov. 4 – 7 at the Las Vegas Convention Center, Mazak will showcase advanced metalworking technology for specialty automotive part production. In booth 10519, the company will demonstrate how its latest small-footprint machine tools can bring increased productivity and profitability to high-performance custom and production shops.

Throughout the show, Mazak will have its VERTICAL CENTER UNIVERSAL (VCU) 400A 5X, VERTICAL CENTER UNIVERSAL (VCU) 500A and QUICK TURN SMART (QTS) 200M machines perform real-world cutting demonstrations of automotive parts.

Applications engineers will also be available to discuss the full benefits of these high-performance, high-value machines, which include unmatched accuracy, short part cycle times and the versatility to adapt to rapid shifts in production.

The VCU 400A 5X machining center employs a 5-axis rotary/tilt trunion table with durable, high-speed roller gear cam technology to affordably produce small complex parts up to 15.74″ in diameter and 12″ high. The machine’s standard 10,000-rpm, CAT 40 spindle is also available in 12,000 and 20,000 versions. Furthermore, a standard 30-tool or optional 40-tool storage capacity ensures continuous machining operation.

The simple but innovative VCU 500A vertical machining center with a 3-axis table brings advanced technology and production value to small parts processing for a variety of industries. This 3-axis machine accurately processes basic part geometries up to 19.68″ wide x 19.68″ deep x 12″ tall. And like the VCU 400 series, the machine’s standard 10,000-rpm CAT 40 spindle is also available in 12,000 and 20,000 versions.

The QTS 200M turning center provides high performance and unsurpassed production value for small to medium-sized parts. As an “M” configuration, the machine adds milling, drilling and tapping to its turning capability. This gives the machine multi-tasking abilities for even shorter part processing times. A 25-hp, 6,000-rpm spindle drives the machine’s 8″ chuck, providing ample power for machining a wide variety of materials. In addition, the 12-position turret and 4,500-rpm, 7.5-hp milling spindle provide true multi-tasking capability.

These are just three solutions within Mazak’s comprehensive selection of machine tools that meet the urgent demands and just-in-time logistics of the automotive part manufacturing industry. Whether SEMA attendees produce cylinder heads, brake discs or axle shafts, Mazak can help them identify the best machining technology for their needs.
