Overview
The Mazak Power Master series consists of two large, slow-turning, high-torque turning centers: the POWER MASTER Chucker for big-diameter chuck work and the POWER MASTER Universal for long shafts. Both use a 1,200 rpm spindle rated 45 kW (60 HP) at 40% ED and 37 kW (50 HP) continuous, with 5,369 ft-lb (7,279 Nm) of torque at 40% ED.
That torque is the reason the series exists. Large diameters with heavy machining allowances need cutting force at low speed, and the headstock delivers it through a 4-stage hydraulic shift. Mazak states that full-power cutting at 45 kW (60 HP) is available even on a Ø23.62 in workpiece. The smallest listed spindle bore is Ø4.65 in, and Mazak also lists Ø10.24 in, Ø12.6 in and Ø14.76 in bores, which open the machine to pipe and other hollow work.
The two models differ in turret and bed. Mazak gives the Chucker a maximum machining diameter of Ø39.37 in with standard indexing tooling on its octagonal turret, which indexes in 3.2 seconds per step. The Universal pairs a front 8-station disc turret, holding 8 tools of 1.26 in × 1.26 in × 6.30 in, with a rear hexagonal boring turret for 6 tools. Only the Universal takes the tailstock: a 5.91 in quill with a built-in MT No.5 centre, clamped to the bed with 12 tons of force and able to support workpieces up to 3 tons.
In the table, maximum turning diameter runs from Ø33 in (838 mm) to Ø39 in (991 mm), swing is 34 in (864 mm) over the bed and 42 in (1,067 mm) over the gap, and Z travel runs from 45 in (1,143 mm) to 121 in (3,073 mm). A single bed class appears, 3000U, with a maximum turning length of 118 in (2,997 mm). Rapids are 472 ipm (12 m/min) in both axes and weight runs from 23,336 lb (10,585 kg) to 32,838 lb (14,895 kg). The bed uses equal-angle V-shaped slideways that are heat treated and ground, with inclined chutes to clear chips.

Strengths & Limitations
Strengths
- 5,369 ft-lb (7,279 Nm) of spindle torque at 40% ED through a 4-stage hydraulic shift
- 45 kW (60 HP) at 40% ED and 37 kW (50 HP) continuous, with full-power cutting stated on a Ø23.62 in workpiece
- Spindle bores of Ø4.65 in, Ø10.24 in, Ø12.6 in and Ø14.76 in are listed for the series
- The Chucker reaches a maximum machining diameter of Ø39.37 in with standard indexing tooling
- The Universal carries an 8-station disc turret plus a rear turret for 6 tools, and a tailstock that supports workpieces up to 3 tons
- Optional steady rests span Ø0.79 in to Ø21.65 in across four overlapping ranges
Limitations
- Spindle speed is limited to 1,200 rpm, so small diameters cannot reach an efficient surface speed
- Rapid traverse is 472 ipm (12 m/min) in X and Z, slow over a Z travel of up to 121 in (3,073 mm)
- The table lists an 8-tool turret; the extra 6 tools of the rear boring turret belong to the Universal
- The tailstock is compatible with the Universal only
- Steady rests and rear chuck mounting preparation are options

Frequently Asked Questions
01
The Chucker is the big-diameter machine: an octagonal turret, a maximum machining diameter of Ø39.37 in and a turret index of 3.2 seconds per step. The Universal is for long shafts: a front 8-station disc turret, a rear hexagonal boring turret for 6 tools, and a tailstock that Mazak says is compatible with the Universal only.
02
45 kW (60 HP) at 40% ED and 37 kW (50 HP) continuous, at up to 1,200 rpm. Torque is 5,369 ft-lb (7,279 Nm) at 40% ED, which Mazak describes as twice that of conventional machines, delivered through a 4-stage hydraulic shift in the headstock.
03
Mazak lists four: Ø4.65 in, Ø10.24 in, Ø12.6 in and Ø14.76 in. The three larger bores carry an asterisk on Mazak's page, so confirm how each is supplied. Rear chuck mounting preparation is an option, with covers that open for access and a switch that prevents operation while they are open.
04
The tailstock has a 5.91 in quill with a built-in MT No.5 centre, is clamped to the bed with 12 tons of force and supports workpieces up to 3 tons. Optional steady rests are available for Ø0.79 in to Ø9.84 in, Ø5.91 in to Ø13.78 in, Ø9.84 in to Ø17.72 in and Ø13.78 in to Ø21.65 in.
05
The SLANT TURN 500 turns Ø36 in (914 mm), runs to 1,600 rpm with 37 kW (50 HP) continuous, has a 12-tool turret and rapids of 787 ipm (20 m/min) in X and 945 ipm (24 m/min) in Z, with 46 in (1,168 mm) of Z travel. The Power Master matches its continuous power at a lower 1,200 rpm, carries 8 tools and offers up to 121 in (3,073 mm) of Z travel.
