The 500 mm twin-pallet machine (optional 400 mm pallet size) has a maximum workpiece capacity within a cylinder diameter of 750 mm (900 mm high). The machine`s B-axis has 1,600 Nm of torque and a positioning accuracy of 10 arc-secs (with a repeatability of 6 arc-secs). Also featured is a zero-point clamping system that employs four radial pre-tensioned tapers to ensure alignment. Index times are 1.5 seconds, with a pallet interchange time of 7 seconds.
An integral 22 kW BIG-Plus dual-contact spindle has a speed range of between 40 and 15,000 rpm, with up to 167 Nm of torque available through a low and high range transmission. In order to minimise any deformation caused through variable cutting forces or thermal effects, the spindle head is mounted between twin box-type gantry columns, while the cast iron bed is supported via three-point levelling.
The machine’s 60-tool magazine is capable of carrying tools up to 80 mm diameter (or 160 mm with adjacent pockets left empty). Maximum tool length is 400 mm. Control is by Fanuc 0i-MF.
