Mazak Powers to MACH 2012 with Seven Machine Tools

Yamazaki Mazak will display the ‘Power of Mazak’ with seven machine tools at MACH 2012, each highlighting the exceptional productivity and performance that is available to machine tool users.

Each of the machines on display, many of which have been manufactured in the UK, will be live-cutting throughout the show and technical advice will be on hand capable of answering specific machining questions from attendees.

Taking centre stage will be the new ORBITEC 20, a specialist valve body production machine, which is making its MACH debut. The ORBITEC 20 has been specifically developed for turning eccentric large features of an irregular shape, which are not conducive to normal turning operations.

The ORBITEC 20 moves the cutting tool while the turned part, such as a valve, remains in a fixed position. The machine is capable of completing a variety of valve features, including the facing of flange surfaces, conical boring of taper holes, face milling, end milling, threading, internal grooving, concave machining and phonographic finishing. 75 per cent of valve applications can be completed in one set-up, while maintaining high tolerances.

Multi-tasking machines will be represented by the INTEGREX i-400 ST, the next generation of the phenomenally successful INTEGREX series.

The latest INTEGREX series of machines are equipped with a number of improvements and new technologies which significantly improve performance. The i-400 ST machine has a larger working area, particularly in the Y-axis which has a range of up to 250 mm, along with 615 mm in the X-axis and B-axis range of 240o. In addition, each axis is also equipped with rigid linear roller guides to give improved positioning accuracy with lower friction.

The main spindle has 30 kW of power based on a 30 minute rating, while milling spindle power has been increased to 22 kW for a 30 minute rating and is capable of 12,000 rpm. Both main and milling spindles are equipped with heat countermeasures which work by circulating cooled oil around the spindles, to ensure consistent accuracy and dimensional positioning.

The INTEGREX i-400 ST will be joined on the Mazak stand by the INTEGREX i-630 V, a vertically configured INTEGREX capable of machining large workpieces. The i-630V has been specifically designed for the machining of heavy duty applications across a broad range of industries, from aerospace to oil and gas applications and is capable of machining components with dimensions up to 1,050 mm by 1,000 mm and a weight of up to 1,750 kg.

The machine was developed in response to market requirements for a multi-tasking machine with improved rigidity, a compact 5-axis tilting head, large pallet size (630 mm x 630 mm) and reduced floorspace. In fact, the new machine, which utilises a column-type design, has a footprint of only 4,960 mm width and 6,500 mm depth.

Mazak machining centres will be represented by two machines from the Mazak Variaxis range. The Variaxis j-500 is an entry-level multi-tasking machine offering high productivity and high accuracy.

High accuracy is guaranteed with roller gear cams on the A/C axis; ball screw core cooling and a tilting rotary table which is supported on both ends to increase rigidity and eliminate any sagging, in comparison to a cantilever-type design. In addition, high performance is achieved by the 12,000 rpm spindle and rapid traverse rates of 30 m/min across all five axes.

The j-500 will be joined on the Mazak stand by the Variaxis i-700, a simultaneous 5-axis machining centre that is equipped with an extended Y axis for the inclined machining of tall workpieces. Like the j-500, the i-700 is equipped with high accuracy roller gear cams on both the A and C axes and roller guides on its linear axes. High productivity is achieved with an 18,000 rpm spindle and rapid traverse rates of 60 m/min on the X and Y axes and 56 m/min on the Z-axis.

Vertical machining centres will be represented by the Vertical Centre Smart 430A, Mazak’s entry-level machining centre. Specifically developed with a view to reducing machining cycle times, the spindle of the Vertical Centre Smart comes equipped with a 40-taper nose and generates 18.5 kW of power at a maximum torque of 95.5 Nm.

Rapid traverse rates are a brisk 42 m/min and fast and reliable tool changing means downtime is minimised to 1.3 seconds (tool-to-tool) and 4.4 seconds (chip-to-chip) due to the cam drive on the tool change mechanism. The machine is equipped with powerful direct drive spindles, roller linear guides on all axes and the Mazatrol Smart Control which makes the VC Smart 430A up to 73 per cent faster to programme compared to EIA/ISO control systems.

Mazak turning centres will be represented by the Quick Turn Smart 300M, a simplified 2- and 3-axis turning centre that is packed with high performance features at a surprisingly affordable level of investment. The 300M is available with powerful direct drive spindles, linear guides, a compact fast-indexing tool turret and NC tailstock. Crucially, the machine is also equipped with a milling function which delivers 7.5 kW of power for high productivity and accuracy.

Tony Saunders, UK Sales Director for Yamazaki Mazak, commented: “MACH 2012 will feature seven Mazak machines, some of them like the Quick Turn Smart built in the UK, and all offering exceptional levels of performance and productivity. We are confident that machine tool users of all sizes, from the smallest subcontract shop to the most sophisticated manufacturer will find the technologies they need to take their machining capabilities up to the next level.”
