Yamazaki Mazak unveiled the Hyper Variaxis 630 high-speed, high-precision, multi-surface simultaneous five-axis machine and the Horoizontal Center Nexus 6000 for general-purpose tasks at Mach 2010.

The Hyper Variaxis 630 machine is the result of the design partnership between Yamazaki Mazak and the Ken Okuyama Design Company.

The machine structure and the use of direct-drive linear motors provide improved performance while the aesthetics of the machine have been created as one of flow, with very few square corners.

The machine also offers simplified setup, thanks to the ability to open the front door and top cover of the machine to provide ‘walk-in’ access to the machine table and cranage of larger components directly onto the table.

The Hyper Variaxis 630 is a gantry-type machine, with the fourth and fifth axes (A and C) being provided by a high-speed tilting and rotating trunnion table capable of rotational speeds of 50rev/min (A axis) and 120rev/min (C axis) respectively.

These axes are powered by direct-drive motors with 4,300Nm and 1,800Nm of torque respectively.

The design of the gantry reduces the overhang of the X , Y and Z axes and, with the addition of the linear motors on these axes (tandem motors on the Y axis), traverse rates of up to 80m/min are achieved, while at the same time enhancing the accuracy of the machine and the quality of the machined components across its 630mm (X-axis), 1,100mm (Y-axis) and 600mm (Z-axis) travels.

The spindle itself is a high-power, high-speed unit (35kW/168Nm/18,000rev/min, with a 30,000rev/min option).

With target customers operating in the general sub-contract and automotive sectors, the Horoizontal Center Nexus 6000 is claimed to provide advanced technology, high productivity and good value from a ‘compact’ machine.

Spindle power has been increased from 30kW to 37kW, rapid traverse rates are up to 60m/min from 40m/min and acceleration is up by 40 per cent to 0.7G.

Productivity is further enhanced by improved spindle acceleration, with the maximum spindle speed of 10,000rev/min being achieved in three seconds and chip-to-chip tool changes taking three-and-a-half seconds.

Users of the HCN6000 will also benefit from the largest workpiece capacity in this class of machine tool.

The 750 x 500mm rotary table can carry components weighing up to 1,000kg and measuring 1m in height and 900mm in diameter, with axis movements of 800mm in the X, Y and Z axes, ensuring that the maximum advantage is taken of this load-carrying ability.

Ergonomics have also been addressed with the design of the HCN6000, with one example being the simple repositioning of the control panel.

In its new position, with the operator facing towards the front of the machine, it is said to be easier to see inside the machining area and, when ‘driving’ the machine manually, the machine movements (+/-) on the control are no longer the opposite of those on the machine, as operator and machine are in the same relative position.

Yamazaki Mazak Ltd

Yamazaki Mazak is the world’s largest manufacturer of computer controlled (CNC) metal-cutting machines. With over 260 different models, the Mazak product range includes CNC lathes, machining centres, multi-tasking machines and flexible manufacturing systems as well as laser processing machines.

Machine tools are called “Mother Machine” because they relate to the manufacturing of almost every product around us and are very important in supporting the base of “world manufacturing.” Our mission as a machine tool maker is to enrich people’s lives and contribute to society by developing and providing high performance machine tools that can produce high accuracy work in a short time.

We were among the first to start foreign production as a Japanese machine tool maker. Following the establishment of Mazak Corporation in the USA, we expanded our production base worldwide to include the UK, Singapore and China, as well as further expanding our Japanese manufacturing operations. We are the only machine tool maker to have established a global production system. With these local plants, we have been able to provide high quality service and have built strong relationships based on mutual trust with customers from all over the world.

True to the Yamazaki principle of supporting the customer locally, Mazak’s European Manufacturing plant, in Worcester UK, opened in June 1987 and was immediately recognised as the most advanced machine tool manufacturing plant in Europe. The factory has expanded three times since then and now offers over 29,000m2

This is a complete machine tool manufacturing plant. Mazak machines the components that go to make its spindles, turrets, tool magazines and Mazak even manufactures its own sheet metal covers. As with all Mazak manufacturing plants, the most rigorous practices and Kaizen programmes ensure continuous improvement.

Serving all of Europe’s markets, more than 80% of the machine tools built in Worcester are exported from the UK into Europe. More than 17,000 Mazak machines have been manufactured here so far and this number continues to grow every day.

Mazak European Manufacturing Plant is recognised for its factory automation, technology and overall management practices. Selected as one of the “Top Ten Companies in the World” by the Swedish Royal Academy of Science and Technology underscores this worldwide reputation.

As with all Mazak factories, this facility comprises a variety of flexible manufacturing systems, consisting of machining centres, multi-tasking CNC lathes, and a sheet metal FMS – all designed for unmanned operation.

The plant benefits from highly skilled employees who are committed to continuous improvement through the 25 “Kaizen” teams in operation.
