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 names four machines in its QRX two-turret series, and the QRX-50MSY SG is the one configured with milling, a second spindle and a Y-axis together. It is a 6 in chuck machine at both ends, 6,000 rpm on either spindle, weighing 17,637 lb (8,000 kg).

A part moves through it like this. Bar stock is turned in the main spindle while the upper and lower turrets cut together, the part is passed to the second spindle, and the back is finished there while the main spindle starts the next piece. Mazak calls this simultaneous left and right hand machining and aims the second-spindle QRX models at mass production of bar shapes. Because the second spindle has the same 11 kW (15 HP) continuous, 15 kW (20 HP) (40% ED) motor as the main, work can be divided between the two sides by cycle time instead of by which side has the power.

Two turrets in one work area make interference the main risk during prove-out, and much of what Mazak says about the series control addresses it. The display is divided into two columns, one per turret. In inter-grid single block operation, every turret stops when one of them completes a process. Override applies to standby time as well as operating time, so the turrets stay synchronised when the operator slows the program down, and the program can be stepped through by turning the handwheel. Balance cutting and simultaneous machining are programmed in conversational MAZATROL.

Rotary tools run to 6,000 rpm on 1.8 kW (2 HP) continuous, 5.3 kW (7 HP) short-time, and the Y-axis traverses at 709 ipm (18 m/min). X and Z rapids are 1,181 ipm (30 m/min) and 1,575 ipm (40 m/min). The table stops there: it states no turning diameter, length, bar capacity or travels, so ask Mazak for the envelope.

Strengths & Limitations

Strengths

Second spindle matches the main spindle: 6 in chuck, 6,000 rpm, 11 kW (15 HP) continuous and 15 kW (20 HP) (40% ED) on each
Two turrets and two spindles let front and back operations overlap, which Mazak says shortens cycle time across the QRX series
Series control functions aimed at two-turret prove-out: a two-column display, inter-grid single block operation and override that keeps the turrets synchronised
Y-axis with a 709 ipm (18 m/min) rapid and rotary tools to 6,000 rpm for off-centre features
BMT45 tool holders on the series' 12 station drum turret (24 position) can be mounted reversed by 180°

Limitations

With 1.8 kW (2 HP) continuous at the rotary tool spindle, milling is limited to small cutters and light passes
A 6 in chuck on each spindle sets the part size; the QRX-50 has an 8 in chuck but no second spindle
No turning diameter, turning length, bar capacity or travel figures are given in Mazak's table for this model
The unloader, bar feeder and parts catcher that make unattended running possible are all optional

Best For

High-volume bar parts needing front and back machining in one handling Splitting work between two equally rated 11 kW (15 HP) continuous spindles Parts with off-centre drilled or milled features that need a Y-axis Automatic production cells built around a bar feeder and workpiece unloader

Frequently Asked Questions

01 Can both turrets of the QRX-50MSY SG cut at the same time?

Yes. Mazak describes the QRX series as using upper and lower turrets together to reduce cycle time, and says the two-turret, two-spindle construction of the QRX-50MS SG and QRX-50MSY SG allows simultaneous left and right hand machining. Balance cutting and simultaneous machining are programmed with the conversational MAZATROL program.

02 How is a two-turret program proved out on the QRX series?

Mazak lists several functions for it. The display is split into two columns so each turret's operation can be followed, and the EIA/ISO programming screen shows waiting command positions side by side. Inter-grid single block operation stops all turrets when one completes a process. Override is applied to standby time as well as operating time, which keeps the turrets synchronised, and the program can be run at any speed by turning the handwheel. Safety Shield checks a 3D model for interference during manual axis moves.

03 What are the milling figures for the QRX-50MSY SG?

The rotary tool spindle runs to 6,000 rpm. Its motor is rated 1.8 kW (2 HP) continuous with a short-time rating of 5.3 kW (7 HP). Y-axis rapid traverse is 709 ipm (18 m/min). Those figures suit drilling, tapping and light milling on turned parts; the two turning spindles, at 11 kW (15 HP) continuous each, do the heavy cutting.

04 How do finished parts leave the machine?

Two optional systems are described for the series. A workpiece unloader, offered for the QRX-50MS SG and QRX-50MSY SG as a hand type or a bucket type, takes the finished part from the second spindle while the main spindle is machining. The auto parts catcher uses a bucket attached to the lower turret to carry finished parts from either spindle, and bar remnants, out of the work area.

05 Which QRX model is meant for shafts instead of bar parts?

Mazak lists the QRX-50 SG and QRX-50MY SG as tailstock-specification machines for mass production of shaft shapes. The QRX-50 has an 8 in chuck, a 6,000 rpm spindle rated 11 kW (15 HP) continuous and weighs 16,534 lb (7,500 kg), against 17,637 lb (8,000 kg) for the QRX-50MSY SG.
