INCLUDED IN LATEST MITSUI SEIKI VERTEX 55X III 5-AXIS VMC
The latest addition to the Mitsui Seiki Vertex 5-axis simultaneous control series of vertical machining centres introduces a multi-sensor thermal growth monitoring system MAMS (Mitsui Accurate Milling Support) that enables enhancements in accuracy by creating up to a 35 per cent improvement in minimising Z-axis thermal displacement against previously used machine tool technologies.
Able to produce 5-axis cycles on workpieces within an envelope of 750 mm diameter by 525 mm high, the Mitsui Seiki Vertex 55X III, now available through 2D CNC Machinery of Hinckley, incorporates rapid traverse rates of 48 m/min to positioning accuracies of +/- 1 micron over the 550 mm in X by 600 mm in Y and 500 mm in Z- axis travels. Meanwhile, small point-to-point surface movements are also realised due to the advantage gained by greater rigidity of the machine design.
Workpieces are held upon a 360 deg, 50 revs/min C-axis table of 400 mm diameter able to support loads of 350 kg. The A-axis is +15 to -105 deg while being able to work to a positioning accuracy of +/- 2 mins and with a repeatability of +/- 1.5 mins.
Weighing in at 9.5 tonnes, rigidity in the bed and castings is paramount in maintaining consistent three-dimensional component accuracy. The 40 taper spindle power is 18.5 kW giving 25,000 revs/min with 28.6 Nm of torque available. Tool storage capacity is 40 positions for tools up to 90 mm diameter (125 mm with adjacent pockets left empty) by 300 mm in length.
