Integrex i-150 improvements further enhance axis accuracy

The Yamazaki Mazak Integrex i –150, 2,200 by 2,420 mm footprint machining centre, launched at MACH 2008, is designed for manufacturing small, complex components in as few operations as possible. Recent enhancements include a rotary scale and a reduced distance from the spindle face to the pivot point. These features work together to reduce mechanical movement, increase rigidity and, therefore, increase the accuracy of the axis in any position. The multifunction machine has a bar capacity of 65 mm and a maximum turning diameter of 400 mm with highly specified turning and milling spindles. The 5000 rpm, 11 kW turning spindle and 12,000 rpm 7.5 kW milling spindle are suited to a multitude of tasks from heavy duty rough cutting to high speed cutting of aluminium and other non-ferrous materials. This machining performance is enhanced by the robust design of the major castings that results in a solid machining platform weighing in at some 7,100 kg. This platform consists of a travelling column with X, Y and Z axes travels of 370, 200 and 435 mm respectively. In addition, as with the larger machines in the range, the Integrex i-150 has a B-axis to give true multi-axis capability. This B-axis makes use of a roller-gear cam mechanism, combined with a full circumferential clamp and brake, eliminating the need for a Hurth coupling.
