Axis drives up to 54 m/min with a high torque 600 Nm spindle drive in a more compact, high rigidity horizontal machining centre structure are key features of the 630 mm square pallet capacity Mitsui Seiki HPX63 ll, now available from 2D CNC Machinery of Hinckley.
The new machine qualifies as a high precision production centre with both positioning and repeatability in X, Y and Z axes within +/- 0.001 mm achieved through standard fitment linear scales, while being capable of high performance removal of a wide range of materials spanning aluminium to tough alloy steels.
Taking a floor area of 5,554 mm by 3,374 mm (some 14 per cent smaller than the previous generation machine) strokes in the X-axis are 1,000 mm, 800 mm in Y and 500 mm in Z. The maximum workpiece size for processing is within a cylinder having the same diameter and height of 1,050 mm with a maximum table loading of 1.2 tonnes.
Spindle power is 18.5 kW with a maximum speed of 6,000 revs/min and a high torque value of 600 Nm. There is capacity for 60 tools up to 500 mm in length and up to 265 mm in diameter with adjacent pockets left empty.
Control is by Fanuc 31i-B and spindle growth compensation software and gap sensing are available.
