Milltronics VM200-5X

The Milltronics VM200-5X is a compact 5-axis vertical machining center with a 7.8 in (198 mm) diameter rotary table, 21 x 16 x 19 in (533 x 406 x 483 mm) of X, Y and Z travel and a 10,000 rpm BIG-PLUS ISO No. 40 spindle. The C axis turns through 360° and the A axis tilts from +30° to -110°. That A range passes the right angle on one side, which gives the tool access to undercut faces without a second clamping.

Size the work against the table before anything else. It is 7.8 in (198 mm) across, rated for 330 lb (150 kg), and slotted with 0.39 in (9.9 mm) T-slots at 60-degree radial locations. The distance from spindle nose to table runs from 0.8 to 19.8 in (20 to 503 mm), and that gap has to hold the fixture, the part and the tool together. In practice this is a machine for small parts on a centred fixture, not for plate work.

Spindle power is listed as 10/7.5 hp (7.5/5.6 kW) and the table gives no torque figure, which puts the VM200-5X at the light end of the Milltronics verticals. The VM3018 carries the same taper and the same 10,000 rpm with 20/15 hp (14.9/11.2 kW). Expect finishing and moderate roughing with cutters sized to the motor. The 24-tool double-arm changer takes CT40 holders with MAS 60 retention knobs, and each tool can be up to 3.5 in (89 mm) in diameter, 9.8 in (249 mm) long and 15 lb (7 kg).

Linear rapids are 945 ipm (24.0 m/min), cutting feed reaches 500 ipm (12.7 m/min) and the rotary axes are listed at 25 rpm. Milltronics states positioning accuracy of ±0.0004 in (±0.010 mm) and repeatability of 0.0002 in (0.005 mm). The machine weighs 7,738 lb (3,510 kg), stands 101 in (2,565 mm) high and needs a nominal operating footprint of 76 x 101 in (1,930 x 2,565 mm). The control is the Milltronics INSPIRE+ with a 19 in colour LCD touch screen. The power requirement is listed at 18 kVA; confirm the supply voltage and breaker size with Milltronics when ordering.
