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 SLANT TURN 550 is chosen for its spindle bore. At Ø11 in (279 mm), the hole through the spindle sits between the Ø7 in (178 mm) of the SLANT TURN 500 and the Ø15 in (381 mm) of the SLANT TURN 600, and it comes with a 21 in chuck and a 1,000 rpm top speed.

A bore that size changes how long hollow work is held. Pipe, tube and forgings that fit the bore can pass back into the headstock, so the end being machined stays close to the chuck instead of hanging out over the bed. The chuck and draw tube fitted will reduce the usable opening, so settle that with Mazak. What is given up is speed: 1,000 rpm here against 1,600 rpm on the SLANT TURN 500. On large diameters that rarely costs anything. It matters when the same part has small bores or a face that runs to the center.

Mazak's table for this model covers the Chucker bed. Maximum turning diameter is Ø36 in (914 mm), maximum turning length is 40 in (1,016 mm), and the travels are 18 in (457 mm) in X and 46 in (1,168 mm) in Z. Across the SLANT TURN 500, 550 and 600 series Mazak quotes machining lengths from 40" to 161.38", so longer center distances exist in the family. The figures on this page are for the shortest.

The drive is rated 37 kW (50 HP) continuous and 45 kW (60 HP) on the 30 min. rating, with 5,163 ft-lb (7,000 Nm) of intermittent torque on the low speed winding in low range. A 12-tool turret takes 1 in (25 mm) shanks and Ø2 in (51 mm) boring bars. The machine weighs 30,864 lb (14,000 kg).

Strengths & Limitations

Strengths

Ø11 in (279 mm) spindle bore, against Ø7 in (178 mm) on the SLANT TURN 500
21 in chuck with a Ø36 in (914 mm) maximum turning diameter
5,163 ft-lb (7,000 Nm) of intermittent torque (low speed winding, low range) for heavy cuts at large diameter
37 kW (50 HP) continuous and 45 kW (60 HP) on the 30 min. rating, the same continuous rating Mazak lists for the SLANT TURN 500
Rapids of 787 ipm (20 m/min) in X and 945 ipm (24 m/min) in Z

Limitations

Top speed is 1,000 rpm; the SLANT TURN 500 reaches 1,600 rpm with its smaller bore
Maximum turning length on the Chucker bed is 40 in (1,016 mm), and the table shows no tailstock rows
No rotary tools in this table: the Milling configuration is the SLANT TURN 550M
Boring bars are limited to a Ø2 in (51 mm) shank in the turret, which restricts how deep a large bore can be reached rigidly

Best For

Couplings, sleeves and tube ends that pass through an Ø11 in (279 mm) bore Large rings and flanges held in a 21 in chuck Low-speed roughing of diameters up to Ø36 in (914 mm) Chucking work no longer than 40 in (1,016 mm)

Frequently Asked Questions

01 What is the spindle bore of the SLANT TURN 550?

Mazak lists a Ø11 in (279 mm) spindle bore with a 21 in chuck. That is the middle size of the family: the SLANT TURN 500 has Ø7 in (178 mm) and the SLANT TURN 600 has Ø15 in (381 mm). The usable through-hole depends on the chuck and draw tube fitted, so confirm it for the stock you plan to run.

02 Why is the top speed of the SLANT TURN 550 only 1,000 rpm?

Speed falls as the bore grows in this family. The SLANT TURN 500 runs to 1,600 rpm with a Ø7 in (178 mm) bore, this model to 1,000 rpm with Ø11 in (279 mm), and the SLANT TURN 600 to 500 rpm with Ø15 in (381 mm). A larger bore means larger spindle bearings, which is the usual reason for a lower speed limit.

03 How long a part can the SLANT TURN 550 turn?

The table on this page is for the Chucker bed and lists a maximum turning length of 40 in (1,016 mm) with 46 in (1,168 mm) of Z travel. Mazak quotes machining lengths from 40" to 161.38" across the SLANT TURN 500, 550 and 600 series, so ask about the longer center distances if the work is shaft-like.

04 Is there a SLANT TURN 550 with rotary tools?

Yes. Mazak configures the SLANT TURN 550M with Milling, and that model's table adds a 4,000 rpm rotary tool spindle and lists 41 in (1,041 mm) of turning length. Bore, chuck and main spindle speed match this model: Ø11 in (279 mm), 21 in and 1,000 rpm.

05 Can a steady rest be fitted to the SLANT TURN 550?

Mazak offers a self-run automatic steady rest as an option in the series, with a maximum size of Ø16.14". It states that on the SLANT TURN 500, 550 and 600 series the option is only compatible with the 2000U / 3000U / 4000U beds. The table on this page is for the Chucker bed, so a steady rest means choosing one of the longer beds.
