Our best estimate for a cnc lathes / turning center in this class — not a quote from Yamazaki Mazak. Configuration moves it a long way.

Overview

The Mazak Mega Turn 900 turns up to Ø36 in (914 mm) on a table rated for 6,614 lb (3,000 kg), with a 1,250 rpm spindle that produces 2,696 ft-lb (3,655 Nm) of torque at a 40%ED rating. It is built for heavy, slow cuts on big parts, and Mazak backs that with a published cutting example.

That example, given for the 900 series, is in S45C steel at 80 rpm with a feed of 0.03 IPR and a 0.31 in depth of cut. Mazak states a material removal rate of 58.6 in³/min for it, at the 30 kW (40 HP) (40% ED) output and the maximum torque of 3,655 Nm. The continuous rating is 22 kW (30 HP), the same continuous figure the MEGA TURN 600 carries, so what this size adds is torque at low speed, not a larger continuous motor rating.

Travels grow with the diameter. X is 19 in (483 mm) and Z is 34 in (864 mm), against 14 in (356 mm) and 20 in (508 mm) on the MEGA TURN 600, which also stops at Ø25 in (635 mm) and 1,543 lb (700 kg). Rapids are 945 ipm (24 m/min) on both axes. The 12-tool turret takes a 1 in (25 mm) shank height and Ø2 in (51 mm) boring bars.

This is also the size at which Mazak lists a two-pallet changer as an option, for the 900 and 900M. With it the next workpiece is set up while the current one is being cut, which counts when every part takes real time to load and true up. Mirror-image versions are available as well.

The machine weighs 30,864 lb (14,000 kg), stands 134 in (3,404 mm) tall and occupies 94 in (2,388 mm) × 117 in (2,972 mm) with the MAZATROL SmoothEz control. Milling is not in this model's table; the MEGA TURN 900M is the version with a rotary-tool spindle.

Strengths & Limitations

Strengths

2,696 ft-lb (3,655 Nm) of spindle torque (40%ED) with 30 kW (40 HP) (40% ED) output
Mazak's 900 series cutting example reaches 58.6 in³/min in S45C at 80 rpm
6,614 lb (3,000 kg) table load, against 1,543 lb (700 kg) on the MEGA TURN 600
Ø36 in (914 mm) turning diameter with 34 in (864 mm) of Z travel for taller parts
Two-pallet changer offered as an option on this size, so setup can overlap with cutting
Mirror-image versions are available for layouts in which one operator runs two machines

Limitations

Spindle speed stops at 1,250 rpm, where the MEGA TURN 600 reaches 2,200 rpm
Rapids are 945 ipm (24 m/min); the MEGA TURN 600 moves at 1,181 ipm (30 m/min)
The two-pallet changer is an option, not part of the base machine
No rotary-tool spindle in this model's table; milling requires the MEGA TURN 900M
At 30,864 lb (14,000 kg) and 134 in (3,404 mm) tall, it needs foundation and clearance checks before delivery

Best For

Heavy roughing of steel parts up to Ø36 in (914 mm) Workpieces up to 6,614 lb (3,000 kg) on the table Long-running jobs where a two-pallet changer keeps the spindle cutting during setup Low-speed, high-torque turning at up to 2,696 ft-lb (3,655 Nm) (40%ED)

Frequently Asked Questions

01 How much metal can the Mega Turn 900 remove?

Mazak's example for the 900 series gives a maximum material removal rate of 58.6 in³/min in S45C steel, at a spindle speed of 80 rpm, a feed of 0.03 IPR and a 0.31 in depth of cut. The same example quotes 30 kW (40 HP) at 40% ED and a maximum torque of 3,655 Nm. It is a peak figure under those conditions, not a rate to plan every cut on.

02 What are the spindle ratings?

Maximum speed is 1,250 rpm. Power is 22 kW (30 HP) continuous and 30 kW (40 HP) at 40% ED, and torque is 2,696 ft-lb (3,655 Nm) at 40%ED. The torque and the higher power figure are intermittent ratings, so sustained roughing should be sized on the continuous 22 kW (30 HP).

03 Is a pallet changer available on the Mega Turn 900?

Yes, as an option. Mazak lists a two-pallet changer for the 900 and 900M and describes its purpose as setting up the next workpiece during the machining of the current one, with continuous machining of the first and second pallets for long running periods.

04 How does the Mega Turn 900 compare with the MEGA TURN 600?

The MEGA TURN 600 turns Ø25 in (635 mm), carries 1,543 lb (700 kg), has 14 in (356 mm) of X and 20 in (508 mm) of Z and weighs 21,605 lb (9,800 kg). This model turns Ø36 in (914 mm), carries 6,614 lb (3,000 kg), has 19 in (483 mm) of X and 34 in (864 mm) of Z and weighs 30,864 lb (14,000 kg). Both have a 22 kW (30 HP) continuous spindle rating and a 12-tool turret.

05 What should be checked before installation?

Weight and height first: 30,864 lb (14,000 kg) and 134 in (3,404 mm). The footprint Mazak quotes with MAZATROL SmoothEz is 94 in (2,388 mm) × 117 in (2,972 mm). If the pallet changer option is ordered, ask Mazak for the footprint with it, since the table figure does not say it is included.
