Mazak to unveil two machining centres at MACH 2010

The Hyper Variaxis 630 is a gantry-type five-axis machining centre, the fourth and fifth axes being provided by a high speed tilting and rotating trunnion table, with speeds of 50 rpm (A-axis) and 120 rpm (C-axis). These axes are powered by direct drive motors with 4,300 Nm and 1,800 Nm of torque, respectively. Traverse rates of up to 80 m/min are achievable along X, Y and Z axes, with respective travels of 630 mm, 1,100 mm and 600 mm. The spindle itself is a 35 kW, 18,000 rpm unit, with 168 Nm torque. For general purpose machining centre work, such as in general subcontracting and the automotive sector, the Nexus 6000 horizontal machining centre provides advanced technology, high productivity and value from a compact machine. The Nexus 6000 horizontal machining centre has a 750 mm by 500 mm rotary table, able to accommodate components weighing up to 1,000 kg, with maximum dimensions of 1 m high and 900 mm diameter. The machining centre has 800 mm travel available in X, Y and Z axes. Maximum spindle speed of 10,000 rpm can be achieved in 3 seconds, with chip-to-chip tool changes taking 3.5 seconds. "These two machines are a perfect example of how Yamazaki Mazak has continued to invest during the recession to ensure that it is best placed to deliver metalcutting solutions as the business climate improves. They also demonstrate how value, innovation and performance is leading to increased productivity and profitability for Mazak customers," says Tony Saunders, Yamazaki Mazak's UK sales director.
