Mazak INTEGREX j

The Mazak INTEGREX j series puts a single B-axis milling spindle where a turret lathe would carry its turret. Four models are listed, the INTEGREX j-200, j-200S, j-300 and j-400, all with a Ø20 in (508 mm) maximum turning diameter, a 12,000 rpm HSK-A63 milling spindle and a 20-tool magazine at the front of the machine.

How the B axis works is the thing to understand before anything else. The milling head is clamped by an index coupling and positions in 5-degree increments from -30° to 190°. One tool can therefore reach outside diameters, end faces and angled features without a tool change, but only at angles that fall on those steps. The table shows two B-axis ranges across the series, -30° to +190° and -30° to +210°, so check which applies to the model being quoted.

The INTEGREX j-200 is the short machine: 20 in (508 mm) of turning length, 18 in (457 mm) of X, 8 in (203 mm) of Y and 22 in (559 mm) of Z, with a 5,000 rpm main spindle rated 7.5 kW (10 HP) continuous, at 16,314 lb (7,400 kg). The INTEGREX j-200S adds a second spindle, a built-in motor unit Mazak calls equivalent to the main spindle, and stretches to 36 in (914 mm) of turning length, 38 in (965 mm) of Z and 20,282 lb (9,200 kg). The j-300 and j-400 account for the remaining ends of the table: X travel up to 24 in (610 mm), Y up to 10 in (254 mm), main spindle power up to 15 kW (20 HP) continuous, a top speed down to 4,000 rpm and weight up to 27,778 lb (12,600 kg).

Milling capacity varies more than the shared 12,000 rpm suggests. Continuous milling power runs from 5.5 kW (7 HP) to 15 kW (20 HP) and continuous torque from 16 Nm (12 ft-lb) to 34 Nm (25 ft-lb), so compare the milling rows model by model if the work includes real stock removal with rotating tools. A tailstock with an MT No.5 centre and 1,574 lb (714 kg) to 2,248 lb (1,020 kg) of thrust supports shaft work, and Mazak states that its stroke clears both the milling spindle and the second spindle.
