Overview

The Mazak MEGA TURN 900M adds a rotary-tool spindle to the Ø36 in (914 mm) MEGA TURN, and Mazak's model list gives its configuration as Milling. The envelope is that of the Mega Turn 900: 19 in (483 mm) of X, 34 in (864 mm) of Z, a 6,614 lb (3,000 kg) table load and a machine weight of 30,864 lb (14,000 kg).

Read the rotary-tool ratings carefully, because they are short-time figures. The table gives 4,000 rpm, a maximum torque of 70 ft-lb (95 Nm) and a 7.5 kW (10 HP) motor, both on a 4 min rating, and a continuous output of only 1.5 kW (2 HP). A cutter that needs the full 7.5 kW (10 HP) can have it briefly. Drilling a bolt pattern or milling a short flat fits that profile. Long milling passes under load do not.

The turning side works on a different scale: 22 kW (30 HP) continuous, 30 kW (40 HP) (40% ED) and 2,696 ft-lb (3,655 Nm) of torque (40%ED) at up to 1,250 rpm. Mazak's cutting example for the 900 series, in S45C at 80 rpm with a 0.8 mm/rev feed and an 8 mm depth of cut, reaches 960 cm³/min. On a part that can weigh 6,614 lb (3,000 kg), finishing the secondary holes without lifting it onto another machine is the practical gain, and it is the case Mazak makes for milling in this series.

Mazak lists the two-pallet changer option for the 900 and 900M, and mirror-image versions are available. The 12-tool turret takes a 1 in (25 mm) shank height and Ø2 in (51 mm) boring bars. The table does not state how many positions are driven, and it has no Y-axis row. Installed, the machine is 134 in (3,404 mm) high on a 94 in (2,388 mm) × 117 in (2,972 mm) footprint with MAZATROL SmoothEz, and it rapids at 945 ipm (24 m/min).

Strengths & Limitations

Strengths

Drilling and milling on parts up to Ø36 in (914 mm) and 6,614 lb (3,000 kg) without moving them to another machine
Rotary-tool spindle to 4,000 rpm with 70 ft-lb (95 Nm) and 7.5 kW (10 HP) on a 4 min rating
Turning spindle keeps 2,696 ft-lb (3,655 Nm) (40%ED) and 30 kW (40 HP) (40% ED)
One of the two models for which Mazak lists the two-pallet changer option
Same travels and 30,864 lb (14,000 kg) weight as the Mega Turn 900

Limitations

Continuous rotary-tool output is 1.5 kW (2 HP); the 7.5 kW (10 HP) figure is a 4 min rating
No Y-axis row in the table, and the model list configuration is Milling only
The number of driven turret positions among the 12 is not stated in the table
1,250 rpm on the turning spindle, against 2,200 rpm on the MEGA TURN 600M

Best For

Large rings and housings that need bolt holes after turning Parts too heavy to re-fixture readily, up to 6,614 lb (3,000 kg) Short milling and drilling cycles within the 4 min rotary-tool rating Pallet-changer cells for long-running work

Frequently Asked Questions

01 How powerful is the milling spindle on the MEGA TURN 900M?

The rotary-tool spindle runs to 4,000 rpm. Its motor is listed at 7.5 kW (10 HP) and its maximum torque at 70 ft-lb (95 Nm), both on a 4 min rating, and the continuous output is 1.5 kW (2 HP). Plan driven-tool operations as short cycles with time between them, not as continuous milling.

02 Does adding milling change the turning capacity?

Not in the listed figures. Turning diameter is Ø36 in (914 mm), table load 6,614 lb (3,000 kg), X travel 19 in (483 mm) and Z travel 34 in (864 mm), which are the figures of the Mega Turn 900 as well. The turning spindle remains at 1,250 rpm with 22 kW (30 HP) continuous.

03 How does the 900M differ from the MEGA TURN 600M?

The MEGA TURN 600M turns Ø24 in (610 mm), carries 1,543 lb (700 kg), has 14 in (356 mm) of X and 20 in (508 mm) of Z, runs to 2,200 rpm 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 runs to 1,250 rpm.

04 Can the MEGA TURN 900M be ordered with a pallet changer?

Mazak lists a two-pallet changer as an option for the 900 and 900M. It lets the next workpiece be set up while the current one is machined. On parts of this weight, loading and truing up are slow, so overlapping them with cutting time is where the option earns its place.

05 Is there a Y-axis or a stated number of driven tools?

The table lists X and Z travels only, and Mazak's model list gives the configuration as Milling without a Y-axis. The turret holds 12 tools, but the table does not say how many of the positions take a rotary tool. Both points are worth confirming with Mazak against the part drawing.
