Mazak INTEGREX i-350ST NEO

The Mazak INTEGREX i-350ST NEO adds a lower turret to a two-spindle, 10 in chuck multi-tasking machine; Mazak's model list gives its configuration as Second Spindle, Lower Turret. That puts a 12,000 rpm B-axis milling spindle above the part and a turret below it, on a bed that turns up to 60 in (1,524 mm) long.

The lower turret has axes of its own. X2 travel is 9 in (229 mm) and Z2 travel is 61 in (1,549 mm), nearly the full 62 in (1,575 mm) of the milling spindle's Z axis, so the turret can follow the work from the main chuck to the second chuck. Both lower axes rapid at 1,575 ipm (40 m/min). The turret takes tools with a 1 in (25 mm) shank height and boring bars of Ø1 in (25 mm) shank diameter, and its maximum machining diameter is Ø17 in (432 mm), compared with Ø26 in (660 mm) for the machine as a whole.

Those figures show what the turret is for. The tooling rows describe shank tools and boring bars, so read it as a carrier for turning tools on diameters up to Ø17 in (432 mm). It lets one spindle be cut from the turret while the milling spindle is busy at the other. Work beyond that diameter is left to the tools in the milling spindle.

The table gives a tool capacity of 12 tools in the rows that describe the lower turret, and no separate magazine count for the milling spindle on this model, so ask Mazak for the magazine size. Spindle ratings are 22 kW (30 HP) continuous at the main, second and milling spindles, with 30 kW (40 HP) at 40% ED on the main and 26 kW (35 HP) at 40% ED on the second. All this hardware weighs 37,037 lb (16,800 kg) on a 197 in (5,004 mm) × 123 in (3,124 mm) footprint.
