Overview

The Mazak QRX-50M is listed as an 8 in chuck turning center with two drum turrets and driven tools on both. Mazak's own list for the QRX series names four models: the QRX-50 SG, the QRX-50MY SG (milling, Y-axis), the QRX-50MS SG (milling, second spindle) and the QRX-50MSY SG (milling, second spindle, Y-axis). A plain M model is not on it, so treat the figures on this page as listed values to confirm with Mazak.

The listed envelope is a maximum machining diameter of Φ245 mm and a machining length of 552 mm, with 52 mm (2.05 in) bar capacity through a Φ61 mm spindle bore. Spindle speed and power appear only as estimates, 5,000 RPM and 18.5 kW (25 hp). The QRX-50, by comparison, has a 6,000 rpm spindle rated 11 kW (15 HP) continuous, so both estimates deserve a check. Listed weight is 8,500 kg (18,739 lb) approx.

What can be said with confidence is what the series is. QRX machines cut with an upper and a lower turret at the same time, and balance cutting and simultaneous machining are programmed in conversational MAZATROL. The series turret is a 12 station drum (24 position) with BMT45 tool holders. Bar feeders, workpiece unloaders and an auto parts catcher are optionally available.

Strengths & Limitations

Strengths

Upper and lower turrets cut together, which Mazak says reduces cycle time across the QRX series
Listed with driven tools on both turrets and BMT45 tool mounting
Listed bar capacity of 52 mm (2.05 in) through a Φ61 mm spindle bore for bar-fed work
Bar feeders, workpiece unloaders and an auto parts catcher are offered as options in the series

Limitations

Spindle speed (5,000 RPM) and spindle power (18.5 kW (25 hp)) are listed as estimates only
Mazak's QRX series list does not include a plain M model, so every listed figure needs confirming for the machine on offer
Listed machining diameter is Φ245 mm and length 552 mm, which rules out larger chuck work and long shafts

Best For

Turned parts with milled or drilled features inside the listed Φ245 mm by 552 mm envelope Bar work up to the listed 52 mm (2.05 in) capacity Simultaneous two-turret cutting on volume parts

Frequently Asked Questions

01 Which models does Mazak list in the QRX series?

Four: the QRX-50 SG, the QRX-50MY SG (milling, Y-axis), the QRX-50MS SG (milling, second spindle) and the QRX-50MSY SG (milling, second spindle, Y-axis). Mazak describes the first two as tailstock-specification machines for shafts and the last two as second-spindle machines for bar shapes. A plain QRX-50M does not appear on the list.

02 What are the listed capacities of the QRX-50M?

The listed figures are an 8 in chuck, a maximum machining diameter of Φ245 mm, a machining length of 552 mm, bar capacity of 52 mm (2.05 in) and a Φ61 mm spindle bore. The listed rapid traverse is 30 m/min (X/Z) and the listed weight 8,500 kg (18,739 lb) approx. Spindle speed and power are given as estimates.

03 What do two turrets add on a QRX lathe?

Mazak's description of the series is that the upper and lower turrets together reduce cycle time. Both can cut one part at once (balance cutting), or work at the same time on the left and right of the machine, and these operations are programmed with the conversational MAZATROL program. The series display is divided into two columns so each turret's operation can be followed.

04 How does the QRX-50M compare with the QRX-50 and QRX-50MSY?

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). The QRX-50MSY has 6 in chucks, the same 6,000 rpm and 11 kW (15 HP) continuous, a Y-axis and weighs 17,637 lb (8,000 kg). The figures listed for the QRX-50M, 5,000 RPM and 18.5 kW (25 hp), are estimates and differ from both.
