Mazak INTEGREX i-200ST NEO

The Mazak INTEGREX i-200ST NEO combines four cutting stations in one 8 in chuck machine: a main spindle, a second spindle, a B-axis milling spindle and a lower turret. Mazak's model list states the configuration as Second Spindle, Lower Turret. Every one of the three spindles is rated 15 kW (20 HP) continuous, which is what distinguishes it from lighter lower-turret machines such as the 6 in INTEGREX i-100ST NEO at 7.5 kW (10 HP) continuous.

Power matters more on an ST than on any other variant because two cuts overlap. When the lower turret roughs a diameter at one chuck while the milling spindle works at the other, each spindle is carrying its own load for the whole cycle. Here the main spindle has 22 kW (30 HP) (40% ED) in reserve and the second spindle 18.5 kW (25 HP) (40% ED), both to 5,000 rpm. The milling spindle matches the second spindle at 18.5 kW (25 HP) (40% ED) and runs to 12,000 rpm with 46.1 Nm (34 ft-lb) of continuous torque.

The lower turret moves 8 in (203 mm) in X2 and 35 in (889 mm) in Z2 at 1,575 ipm (40 m/min), and machines diameters up to Ø16 in (406 mm). Its holders are sized for 1 in (25 mm) shank tools and Ø1 in (25 mm) boring bars. On an 8 in chuck machine with this much spindle power, that shank size is the practical ceiling on depth of cut from below, so plan the heaviest roughing passes for tools that the turret can hold rigidly.

Mazak's table lists 12 tools in the block of lower-turret rows and gives no magazine capacity for the milling spindle on this model; the tailstock INTEGREX i-200 NEO lists 36 tools. Upper travels are 21 in (533 mm), 8 in (203 mm) and 35 in (889 mm), with 33 in (838 mm) of turning length on the 850U bed. The machine weighs 26,080 lb (11,830 kg), measures 138 in (3,505 mm) × 108 in (2,743 mm) and is 103 in (2,616 mm) high.
