Mazak INTEGREX j-200S NEO

The Mazak INTEGREX j-200S NEO carries an 8 in chuck at each end: a main spindle rated 11 kW (15 HP) continuous and a second spindle rated 7.5 kW (10 HP) continuous, both to 5,000 rpm, on a 1000U bed with 36 in (914 mm) of turning length and a Ø20 in (508 mm) maximum turning diameter. Mazak's model list gives its configuration as Second Spindle.

The two spindles are not equal, and that should shape the process plan. At the 40% ED rating the main spindle reaches 15 kW (20 HP) and the second spindle 11 kW (15 HP). Heavy stock removal therefore sits best in the first operation, leaving the second spindle the lighter back-end turning and the milling that follows the transfer. Mazak notes that running first and second operations continuously through to the finished workpiece helps accuracy and cuts setup time where phase alignment matters.

The second spindle rides on a W-axis with 57 in (1,448 mm) of travel and a 1,181 ipm (30 m/min) rapid, which is the motion that brings it to the main chuck for the handover. X, Y and Z are 18 in (457 mm), 8 in (203 mm) and 38 in (965 mm), each at 1,575 ipm (40 m/min).

A single 12,000 rpm milling spindle on an HSK-A63(T63) taper serves both chucks. It is rated 5.5 kW (7 HP) continuous and 7.5 kW (10 HP) (40% ED), with 21.9 Nm (16 ft-lb) continuous and 27.5 Nm (20 ft-lb) (40% ED) of torque, and its B-axis swings from -30° to +210° at 63 rpm. Mazak says of the series that the second spindle, like the main one, can have outer diameter, end face and diagonal machining done with a single tool. The magazine is listed at 20 tools of up to Ø5 in (127 mm) and 11 lb (5 kg). Weight is 20,944 lb (9,500 kg) on a footprint of 149 in (3,785 mm) × 101 in (2,565 mm).
