Mazak INTEGREX i-150

The Mazak INTEGREX i-150 is the compact end of Mazak's INTEGREX mill-turn range: a 6" chuck machine with a milling spindle on a swiveling B-axis, sized for small precision components where the value is in finishing the part complete rather than in removing metal quickly. Maximum machining diameter with the lower turret is Φ340 mm (Φ13 in) and maximum machining length is 385 mm (15 in).

The main spindle runs to 5000 rpm at 11 kW (15 HP) peak and 7.5 kW (10 HP) continuous. The milling spindle turns to 12000 rpm through HSK-A63 at 7.5 kW (10 HP) peak and 3 kW (4 HP) continuous, with 49.1 N·m peak and 19.6 N·m continuous torque. That continuous milling figure is the honest measure of the machine: 3 kW sustained is a finishing and feature-cutting budget, not a roughing one. The i-150 is intended for parts where the milling work consists of small holes, flats, slots and engraving on an otherwise turned component, in materials and sizes where that is enough.

Travels are 370 mm (15 in) in X, 200 mm (8 in) in Y and 435 mm (17 in) in Z, all rapiding at 40000 mm/min (1575 IPM). The B-axis swings -10° to +190° with a 0.0001° minimum increment. The relatively shallow -10° negative limit is worth noting when planning approach angles, as it restricts how far the head can lean back below horizontal compared with larger machines in the family.

Tooling is where the i-150 is unexpectedly generous. The magazine holds 36 tools taking up to Φ90 mm diameter, Φ125 mm with an adjacent pocket empty, 210 mm long and 5 kg. Thirty-six pockets on a machine this small means a complete turning and milling set for several jobs can live in the magazine at once, which is what makes short-run and unattended work practical.

At 7300 kg on a 2320 × 2500 mm footprint and 2500 mm tall, the i-150 occupies about the floor space of a mid-size lathe. It suits medical, instrument, connector and precision component work where parts are small, tolerances are tight and setups are the dominant cost.
