The new machine qualifies as a high precision production centre with both positioning and repeatability in X-, Y- and Z-axes within ±0.001mm 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 5,554mm by 3,374mm (some 14% smaller than the previous generation machine) strokes in the X-axis are 1,000mm, 800mm in Y and 500mm in Z. The maximum workpiece size for processing is within a cylinder having the same diameter and height of 1,050mm with a maximum table loading of 1.2 tonnes.
Spindle power is 18.5kW with a maximum speed of 6,000rpm and a high torque value of 600Nm. There is capacity for 60 tools up to 500mm in length and up to 265mm in diameter with adjacent pockets left empty. Control is via Fanuc 31i-B and spindle growth compensation software and gap sensing are available.
The Mitsui Seiki HPX63 ll horizontal machining centre has 54m/minute axis drives and 600Nm of torque from the 18.5kW spindle.
