Mazak QTE-200MSY

The Mazak QTE-200MSY is the 8 in chuck QTE turning center that combines all three additions the series offers: Mazak's model list gives its configuration as milling, second spindle and Y-axis. The main spindle runs to 5,000 rpm on 11 kW (15 HP) continuous, or 15 kW (40% ED), with a maximum torque of 123 ft-lb (167 Nm). Swing is Ø27 in (686 mm), maximum turning diameter Ø13 in (330 mm) and bar capacity Ø2 in (51 mm).

The second spindle is what sets it apart from the QTE-200MY, which shares the turning envelope, the 5,000 rpm spindle and the Y-axis. It carries a 6 in chuck, turns at up to 6,000 rpm and is rated 5.5 kW continuous or 7.5 kW (40% ED), half the continuous power of the main spindle. W-axis travel is 23 in (584 mm), so the second spindle can come up to the main chuck, take the part and present its back face to the turret. Second-operation work has to suit that smaller motor and chuck: finishing cuts, drilling and light milling, with the heavy roughing done on the first side.

The 12-tool turret drives rotary tools at up to 4,500 rpm, rated 3.7 kW continuous and 5.5 kW (40% ED) with a maximum torque of 34 ft-lb (46 Nm). That covers cross holes, tapping, keyways and flats with small end mills. The Y-axis moves those tools off the spindle centreline. Mazak's table gives its travel as 3.9 without a unit, on a page otherwise in inches, and its rapid traverse as 394 ipm (10 m/min) against 1,181 ipm (30 m/min) on X and Z.

X travel is 9 in (229 mm) and Z travel 24 in (610 mm), on the bed Mazak codes 500U. For the QTE series as a whole Mazak describes a built-in motor spindle, drum turrets with non-lift indexing and a 25 mm × 25 mm tool shank, and the MAZATROL SmoothEz control. The Ez LOADER collaborative-robot system and a gantry loader are offered as optional automation for the series.
