How much does the Mazak SLANT TURN 550M cost?
Estimated price range
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
Mazak lists the SLANT TURN 550M as the Milling configuration of its Ø11 in (279 mm) bore turning center. A 21 in chuck and a 1,000 rpm main spindle are joined by a 4,000 rpm rotary tool spindle in the turret, on a machine that turns up to Ø36 in (914 mm).
Work for a lathe of this bore tends to be big and hollow: couplings, valve bodies, flanged tube. Much of it finishes with holes, such as a bolt circle on a flange face or a row of tapped ports. Cutting those on the lathe avoids lifting a heavy part onto a second machine and picking it up again. The rotary tool motor is listed at 7.5 kW (10 HP) and 70 ft-lb (95 Nm) on a 4 min rating, with 1.5 kW (2 HP) continuous. It is sized for drilling and tapping cycles, in other words, and less for long slotting passes. Mazak notes that a high-torque milling spindle is optionally available.
For turning, the spindle is rated 37 kW (50 HP) continuous and 45 kW (60 HP) on the 30 min. rating. Intermittent torque is 5,163 ft-lb (7,000 Nm) on the low speed winding in low range. Those match the SLANT TURN 550, which shares the 37 kW (50 HP) continuous rating, so the milling turret does not come at the expense of the main drive.
The table is for the Chucker bed. Maximum turning length is 41 in (1,041 mm), where the SLANT TURN 550 lists 40 in (1,016 mm). X travel is 18 in (457 mm) and Z travel 46 in (1,168 mm); no Y-axis travel is given. Weight is 30,864 lb (14,000 kg).

Strengths & Limitations
Strengths
- Ø11 in (279 mm) spindle bore and a 4,000 rpm rotary tool spindle on the same machine
- Hole patterns and ports can be drilled and tapped in the turning setup, with 70 ft-lb (95 Nm) and 7.5 kW (10 HP) on the 4 min rating
- Main spindle rated 37 kW (50 HP) continuous, with 5,163 ft-lb (7,000 Nm) of intermittent torque in low range
- Ø36 in (914 mm) maximum turning diameter in a 21 in chuck
- A high-torque version of the milling spindle is available as an option
Limitations
- Continuous power at the rotary tool spindle is 1.5 kW (2 HP), far below its 7.5 kW (10 HP) 4 min rating
- Main spindle speed stops at 1,000 rpm, where the SLANT TURN 500M reaches 1,600 rpm
- The table gives X and Z travel only, with no Y-axis row
- The Chucker bed limits turning length to 41 in (1,041 mm)

Frequently Asked Questions
01
The 550M is the Milling configuration. Its table adds a rotary tool spindle: 4,000 rpm, 7.5 kW (10 HP) and 70 ft-lb (95 Nm) on a 4 min rating, 1.5 kW (2 HP) continuous. It also lists 41 in (1,041 mm) of maximum turning length, where the SLANT TURN 550 lists 40 in (1,016 mm). Bore, chuck, main spindle speed and weight are the same in both tables.
02
Work that fits the motor ratings. The rotary tool spindle has 7.5 kW (10 HP) and 70 ft-lb (95 Nm) for 4 min at a time and 1.5 kW (2 HP) continuously, at up to 4,000 rpm. Drilling, tapping and short milling cuts fall inside that. Heavy or prolonged milling does not, unless the optional high-torque milling spindle changes the picture, so ask Mazak for its ratings.
03
Up to Ø36 in (914 mm) in diameter and 41 in (1,041 mm) in turning length on the Chucker bed, in a 21 in chuck. The spindle bore is Ø11 in (279 mm). Travels are 18 in (457 mm) in X and 46 in (1,168 mm) in Z.
04
Mazak lists a footprint of 224 in (5,690 mm) × 96 in (2,438 mm) for the MAZATROL SmoothG configuration, a height of 103 in (2,616 mm) and a weight of 30,864 lb (14,000 kg). Parts of this size are loaded by crane, so check the lifting route to the chuck as well as the floor loading.
