Overview

The Mazak Slant Turn series is a line of large-bore, high-torque turning centers for big shafts and hollow parts. Seven models are listed, the SLANT TURN 500, 500M, 550, 550M, 600, 600M and 800, around a Ø36 in (914 mm) maximum turning diameter, with spindle bores from Ø7 in (178 mm) to Ø15 in (381 mm) and chucks from 18 in to 21 in.

Through the 500, 550 and 600 the bore grows and the speed falls, on the same 37 kW (50 HP) continuous motor and the same 18 in (457 mm) of X travel. The SLANT TURN 500 has an 18 in chuck, a Ø7 in (178 mm) bore and 1,600 rpm. The SLANT TURN 550 has a 21 in chuck, a Ø11 in (279 mm) bore and 1,000 rpm. The SLANT TURN 600 keeps the 21 in chuck, opens the bore to Ø15 in (381 mm) and runs to 500 rpm. So the model number is chosen by what has to pass through the spindle, and what a bigger bore gives up is surface speed on small diameters. Mazak fits these three with a two-step gear shift.

The SLANT TURN 800 stands apart. Mazak gives it a maximum machining diameter of Ø33.86 in, machining lengths of 118.62 in to 158.78 in, a 4 step hydraulic gear shift in the headstock and a tailstock with up to 35 kN of thrust. Whichever model they belong to, the top ends of the power and torque rows show how far the series extends above the SLANT TURN 500: 45 kW (60 HP) continuous, 60 kW (80 HP) on a 30 min. rating and 8,979 ft-lb (12,174 Nm) in the low range.

Bed length is the other choice. The table lists Chucker, 2000U and 3000U classes, with turning lengths of 40 in (1,016 mm) to 80 in (2,032 mm) and Z travel of 46 in (1,168 mm) to 85 in (2,159 mm). Mazak's series text goes further, quoting machining lengths up to 161.38 in for the 500, 550 and 600 and naming a 4000U bed, so ask about longer beds if the table's range is too short.

M models add a milling spindle, with a high-torque version as an option. An optional self-propelled steady rest takes work up to Ø16.14 in; on the 500, 550 and 600 it is compatible only with the 2000U, 3000U and 4000U beds.

Strengths & Limitations

Strengths

Spindle bores from Ø7 in (178 mm) to Ø15 in (381 mm) for pipe, tube and hollow shaft work
Spindle torque of 5,163 ft-lb (7,000 Nm) to 8,979 ft-lb (12,174 Nm) in the low range of the low-speed winding
37 kW (50 HP) to 45 kW (60 HP) continuous, and 45 kW (60 HP) to 60 kW (80 HP) on a 30 min. rating
Bed classes from Chucker to 3000U in the table, with machining lengths up to 161.38 in quoted by Mazak for the 500, 550 and 600
500M, 550M and 600M models add a milling spindle, with a high-torque version optional
Optional CNC-positioned steady rest for work up to Ø16.14 in

Limitations

Spindle speed is 500 rpm to 1,600 rpm, and the SLANT TURN 600 with its Ø15 in (381 mm) bore runs to only 500 rpm
X travel is 18 in (457 mm) on every model
The steady rest is an option, and on the 500, 550 and 600 it fits only the 2000U, 3000U and 4000U beds
No milling model is listed for the SLANT TURN 800
Machines weigh 30,423 lb (13,800 kg) to 49,720 lb (22,553 kg) and stand 103 in (2,616 mm) tall, so plan foundation and rigging

Best For

Pipe, tube and other hollow parts that pass through a large bore Heavy roughing of large-diameter shafts at low speed Long shafts on the 2000U and 3000U beds with tailstock and steady rest Large flanges and discs up to Ø36 in (914 mm) on the Chucker bed Turned parts with milled features on the 500M, 550M and 600M

Frequently Asked Questions

01 How do the SLANT TURN 500, 550 and 600 differ?

Mainly in spindle bore, chuck and top speed. The SLANT TURN 500 has a Ø7 in (178 mm) bore, an 18 in chuck and 1,600 rpm. The SLANT TURN 550 has a Ø11 in (279 mm) bore, a 21 in chuck and 1,000 rpm. The SLANT TURN 600 has a Ø15 in (381 mm) bore, a 21 in chuck and 500 rpm. All three turn Ø36 in (914 mm) with 18 in (457 mm) of X and 37 kW (50 HP) continuous.

02 What is different about the SLANT TURN 800?

Mazak states a maximum machining diameter of Ø33.86 in and machining lengths of 118.62 in to 158.78 in for it. Its headstock uses a 4 step hydraulic gear shift where the 500, 550 and 600 use a two-step gear shift. The tailstock provides up to 35 kN of hydraulic thrust and its quill extends 9.84 in. Mazak's list shows no M version of it.

03 What bed lengths does the Slant Turn series come in?

The table lists Chucker, 2000U and 3000U, with maximum turning lengths from 40 in (1,016 mm) to 80 in (2,032 mm). The SLANT TURN 500 has 41 in (1,041 mm) of turning length on 46 in (1,168 mm) of Z. The SLANT TURN 600 has 79 in (2,007 mm) on 85 in (2,159 mm) of Z. Mazak's series text quotes machining lengths up to 161.38 in for the 500, 550 and 600 and mentions a 4000U bed.

04 How fast are the axes on a Slant Turn?

Rapid traverse runs from 472 ipm (12 m/min) to 787 ipm (20 m/min) in X and from 551 ipm (14 m/min) to 945 ipm (24 m/min) in Z. The SLANT TURN 500 is at the upper figure on both axes, 787 ipm (20 m/min) and 945 ipm (24 m/min).

05 What tooling and work support does the Slant Turn take?

The turret holds 12 tools to 15 tools depending on the model, with a 1 in (25 mm) tool shank height and Ø2 in (51 mm) boring bars. On the 500, 550 and 600 the tailstock quill extends 250 mm, so long and short shafts can be supported without removing the steady rest. The self-propelled steady rest is optional and takes work up to Ø16.14 in.

06 How heavy is a Slant Turn?

Machine weight runs from 30,423 lb (13,800 kg) to 49,720 lb (22,553 kg). The SLANT TURN 500 sits at the light end with 30,423 lb (13,800 kg). The SLANT TURN 550 weighs 30,864 lb (14,000 kg). The SLANT TURN 600, on its longer bed, weighs 39,242 lb (17,800 kg). Machine height is 103 in (2,616 mm).
