Yamazaki Mazak and Ken Okuyama Design are to unveil the Hyper Variaxis 630 and Horizontal Center Nexis 6000 machining centres at Mach 2010.

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 has a simplified set-up 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 carnage of larger components directly on to the table.

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).

These axes are powered by direct drive motors with 4300Nm and 1800Nm of torque respectively.

The design of the gantry reduces the overhang of the X-, Y- and Z-axis 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 machine components across its 630mm (X), 1100mm (Y) and 600mm (Z) axis travels.

The spindle itself is a high-power, high-speed unit (35kW/168Nm/18000rev/min – 30000rev/min option).

For more general-purpose machining, with target customers operating in the general subcontract and automotive sectors, the Horizontal Center Nexus 6000 is said to provide advanced technology, high productivity and value from a ‘compact’ machine.

Spindle power has 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 10000rev/min being achieved in 3sec, and chip-to-chip tool changes taking 3.5sec.

Users of the HCN6000 will also benefit from a large workpiece capacity.

The 750 x 500mm rotary table can carry components weighing up to 1000kg and measuring 1m high and 900mm diameter with axis movements of 800mm in X-, Y- and Z-axis, ensuring 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 re-positioning of the control panel.

In its new position, with the operator facing towards the front of the machine, it is much 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.
