Overview

The Mazak QTE-300MY is listed as a single-spindle turning center whose live tooling turret has a Y-axis. The listed figures give 100 mm (±50 mm) of Y travel, twelve tool stations, rotary tools at 6,000 RPM, and a 4,000 RPM main spindle of 22 kW (30 hp) with an A2-8 nose and 80 mm (3.15 in) bar capacity.

Why the Y-axis matters on a machine like this: with C-axis positioning alone, a rotary tool can only cut on a line through the spindle centre. Y travel lets the tool step sideways, so a flat comes out flat, a keyway has parallel walls and hole patterns can sit off centre. The listed stroke allows 50 mm either side of centre, and the listed Y rapid of 10 m/min (394 ipm) is a third of the 30 m/min (1,181 ipm) on X and Z. With 5.5 kW (7.4 hp) listed for the rotary tools, expect drilling, tapping and moderate end milling.

There is no second spindle in the listed figures, so the cut-off face or back of a part is a separate operation. Listed travels are 230 mm (9.06 in) in X and 620 mm (24.41 in) in Z, and listed weight is 5,600 kg (12,346 lb).

A caution on the model itself. Mazak's QTE series list names eight models in the 100 and 200 sizes, and its Y-axis entries without a second spindle are the QTE-100MY SG and QTE-200MY SG, both configured as Milling, Y-axis. A 300 size is not among them, and the power figures here come without duty ratings. Confirm the specification with Mazak before planning work around it.

Strengths & Limitations

Strengths

Y-axis listed at 100 mm (±50 mm) for flats, keyways and off-centre holes
Rotary tools listed at 6,000 RPM and 5.5 kW (7.4 hp)
Listed bar capacity of 80 mm (3.15 in) with an A2-8 spindle nose
Main spindle listed at 22 kW (30 hp)
620 mm (24.41 in) of listed Z travel

Limitations

No second spindle in the listed figures; the second side of the part needs another setup
Y-axis rapid is listed at 10 m/min (394 ipm) against 30 m/min (1,181 ipm) on X and Z
Not named on Mazak's QTE series list, where the comparable entries are the QTE-100MY SG and QTE-200MY SG
Listed top speed is 4,000 RPM; the QTE-100MY table shows 6,000 rpm for small-diameter work

Best For

Bar parts up to a listed 80 mm (3.15 in) with milled flats or keyways Shafts with off-centre cross holes within 50 mm of centre Turn-mill work completed from one end of the part Chucking work that calls for the listed 22 kW (30 hp) spindle

Frequently Asked Questions

01 What does the Y-axis add on the QTE-300MY?

It lets rotary tools move off the spindle centreline, by a listed 100 mm (±50 mm). That makes true flats, parallel-sided keyways and off-centre hole patterns possible within the turning setup. The listed Y rapid traverse is 10 m/min (394 ipm), and the turret is described as a live tooling turret with Y-axis.

02 Does the QTE-300MY have a sub-spindle?

No sub-spindle figures are listed for it. On Mazak's QTE series list the MY models are configured as Milling, Y-axis, and the second spindle belongs to the MSY models: Milling, Second Spindle, Y-axis. A part that needs back-face machining would be re-chucked.

03 What are the listed spindle and bar figures?

Main spindle speed 4,000 RPM, power 22 kW (30 hp) with no duty rating given, nose A2-8 and bar capacity 80 mm (3.15 in). Mazak states that QTE machines have a built-in motor spindle designed to give high torque in the low-speed range.

04 Is the QTE-300MY on Mazak's model list?

Mazak's QTE series list names QTE-100 SG, QTE-100M SG, QTE-100MY SG, QTE-100MSY SG, QTE-200 SG, QTE-200M SG, QTE-200MY SG and QTE-200MSY SG. There is no 300 size on it. Treat the figures here as listed figures and ask Mazak for its own specification.
