Mazak INTEGREX i-250H

The Mazak INTEGREX i-250H is an 8 in chuck multi-tasking machine from the INTEGREX i-H series, the line Mazak designs with a flat machine front so that robots and stockers can be set against it. Its table gives Ø26 in (660 mm) of turning diameter, 40 in (1,016 mm) of turning length, a 5,000 rpm main spindle and a 12,000 rpm HSK-A63 milling spindle fed from a 38-tool magazine.

That front face is the reason to pick this model. For the series Mazak names a bar feeder, the Ez LOADER, which loads parts with a collaborative robot, the Mazak AUTO FLEX CELL, an articulated robot with stockers arranged across the front of the machine for part loading, chuck jaw supply and special tool exchange, and an auto jaw changer. Mazak marks all four with an asterisk, so confirm which of them a quoted machine includes.

Inside, the working envelope is 27 in (686 mm) of X, 12 in (305 mm) of Y and 42 in (1,067 mm) of Z, with the B-axis covering -30° to +210°. Mazak says of the series that its standard compact milling spindle is 17% shorter overall than the conventional one, which gives the tool more room before it meets the chuck or the tailstock. The tailstock here has an MT No.5 taper and 1,573 lb (714 kg) of thrust.

The turning spindle is rated 15 kW (20 HP) continuous and the milling spindle 22 kW (30 HP) continuous with 91.3 Nm (67 ft-lb) of continuous torque. Against the INTEGREX i-250 NEO, which shares the 28,990 lb (13,150 kg) weight and the same travels, this model lists 38 tools instead of 36 tools and HSK-A63 alone where the NEO lists HSK-T63, HSK-A63. The machine occupies 164 in (4,166 mm) × 106 in (2,692 mm) (W × L) and stands 107 in (2,718 mm) high.
