Our best estimate for a mill-turn / multi-tasking machine in this class — not a quote from Yamazaki Mazak. Configuration moves it a long way.

Overview

The Mazak INTEGREX i-100ST NEO is the fullest configuration of the 6-inch chuck models in the INTEGREX i NEO range: Mazak's model list gives it as Second Spindle, Lower Turret. Below the B-axis milling spindle sits a second tool carrier with its own X2 and Z2 axes, so two tools can be in the cut at once on a machine whose chucks are only 6 in.

The lower turret has 8 in (203 mm) of X2 travel and 35 in (889 mm) of Z2 travel, the same length as the upper Z axis, so it can reach work at either spindle. Both of its axes rapid at 1,575 ipm (40 m/min). Maximum machining diameter with the lower turret is Ø16 in (406 mm), against the Ø24 in (610 mm) maximum turning diameter of the machine. Its tooling is small: a 1 in (25 mm) tool shank height and a Ø1 in (25 mm) boring bar shank. That is ample for the diameters a 6 in chuck holds, but it rules out borrowing heavier boring bars from larger lathes.

A lower turret generally earns its place in two ways: turning at one spindle while the milling spindle works at the other, or cutting a shaft from below while the upper tool cuts from above. Mazak's series page says only that the lower turret specification is offered for process integration, so ask how the two tool carriers can be programmed together. The two turning spindles are identical at 6,000 rpm, 7.5 kW (10 HP) continuous and 11 kW (15 HP) (40% ED). The 12,000 rpm milling spindle is rated 11 kW (15 HP) continuous and 12 kW (16 HP) on a 30 min. rating.

One row needs a question to Mazak. The table gives a tool count of 12 tools, placed with the lower-turret rows, and states no separate magazine capacity for the milling spindle; the INTEGREX i-100S NEO lists 36 tools. Turning length is 33 in (838 mm). The extra hardware brings the weight to 25,419 lb (11,530 kg) and the height to 103 in (2,616 mm).

Strengths & Limitations

Strengths

Lower turret with its own X2 travel of 8 in (203 mm) and Z2 travel of 35 in (889 mm), in addition to the B-axis milling spindle
Lower turret axes rapid at 1,575 ipm (40 m/min), matching the upper Y and Z axes
Second spindle equal to the main: 6 in chuck, 6,000 rpm, 7.5 kW (10 HP) continuous
Z2 travel equals the 35 in (889 mm) upper Z travel, so the lower turret can serve both spindles
Milling spindle torque of 46.1 Nm (34 ft-lb) continuous and 57.3 Nm (42 ft-lb) (40% ED) at up to 12,000 rpm

Limitations

Lower turret tooling is limited to a 1 in (25 mm) shank height and a Ø1 in (25 mm) boring bar shank
Maximum machining diameter at the lower turret is Ø16 in (406 mm), less than the Ø24 in (610 mm) maximum turning diameter
The table lists 12 tools with the lower-turret rows and no magazine capacity for the milling spindle, so that figure has to be confirmed
At 25,419 lb (11,530 kg) and 103 in (2,616 mm) high, it is heavier than the INTEGREX i-100S NEO at 23,876 lb (10,830 kg)
Turning spindles are 7.5 kW (10 HP) continuous, which limits how hard two simultaneous cuts can be pushed

Best For

Small parts in volume where two tools cutting at once shortens the cycle Overlapping operations: turning at one spindle while milling at the other Slender shafts up to 33 in (838 mm) that benefit from a second tool opposite the first Parts needing turning tools on a 1 in (25 mm) shank plus B-axis milling

Frequently Asked Questions

01 What does ST mean on the INTEGREX i-100ST NEO?

Mazak's model list gives the configuration as Second Spindle, Lower Turret. The table bears that out: a second spindle with a 6 in chuck at 6,000 rpm, and lower-turret rows for X2 travel of 8 in (203 mm), Z2 travel of 35 in (889 mm) and a maximum machining diameter of Ø16 in (406 mm).

02 What tooling does the lower turret take?

The table gives a tool shank height of 1 in (25 mm) and a boring bar shank diameter of Ø1 in (25 mm) for the lower turret. A tool count of 12 tools appears with those rows. The milling spindle taper is listed as HSK-T63 and HSK-A63, with tools up to 12 in (305 mm) long and 11 lb (5 kg).

03 How many tools does the milling spindle magazine hold?

The table for this model does not say. Its only tool count is 12 tools, which sits with the lower-turret rows. The INTEGREX i-100S NEO, the second-spindle model of the same size, lists 36 tools. Ask Mazak to confirm the magazine capacity for the ST before planning a tool list.

04 How fast do the axes move?

X rapids at 1,890 ipm (48 m/min); Y and Z rapid at 1,575 ipm (40 m/min). The lower turret's X2 and Z2 axes also rapid at 1,575 ipm (40 m/min). Upper travels are 21 in (533 mm) in X, 8 in (203 mm) in Y and 35 in (889 mm) in Z.

05 How much heavier is the ST than the other 6 in models?

The INTEGREX i-100ST NEO weighs 25,419 lb (11,530 kg). The INTEGREX i-100S NEO, with a second spindle but no lower turret, weighs 23,876 lb (10,830 kg), and the tailstock INTEGREX i-100 NEO weighs 21,892 lb (9,930 kg). Check floor loading and the 103 in (2,616 mm) height against the building.
