Mazak INTEGREX i-250 NEO

The Mazak INTEGREX i-250 NEO is the 8 in chuck model of the INTEGREX i NEO multi-tasking series: a turning center with a B-axis milling spindle, a tailstock and a 36-tool magazine. It turns up to Ø26 in (660 mm) by 40 in (1,016 mm), and the main spindle runs to 5,000 rpm.

What sets this size apart is where the power sits. The turning spindle is rated 15 kW (20 HP) continuous and 22 kW (30 HP) at 40% ED. The milling spindle runs to 12,000 rpm and is rated 22 kW (30 HP) continuous, with 91.3 Nm (67 ft-lb) of continuous torque and 124 Nm (91 ft-lb) at 40% ED. On a continuous basis the tool spindle out-rates the chuck spindle, so the machine suits parts where milling, drilling and contouring fill most of the cycle and the turning is light. A shop that mainly roughs steel at larger diameters should look at the INTEGREX i-350 NEO, which keeps the Ø26 in (660 mm) by 40 in (1,016 mm) envelope but has a 10 in chuck, 4,000 rpm and 22 kW (30 HP) continuous at the turning spindle.

X travel is 27 in (686 mm), Y is 12 in (305 mm) and Z is 42 in (1,067 mm). The B-axis swings from -30° to +210° in 0.0001° increments. Rapids are 1,969 ipm (50 m/min) in X and Z and 1,575 ipm (40 m/min) in Y. The spindle taper is listed as HSK-T63, HSK-A63, and a tool can be Ø4 in (102 mm) with a full magazine, 16 in (406 mm) long and 26 lb (12 kg).

The tailstock has an MT No.5 taper and 1,573 lb (714 kg) of thrust, which makes this the shaft-work configuration. Mazak also offers a second spindle specification in the series for parts that need back-side work. Plan for 164 in (4,166 mm) × 123 in (3,124 mm) of floor, 107 in (2,718 mm) of height and 28,990 lb (13,150 kg). The series control is MAZATROL SmoothAi.
