Overview

The Mazak QTE-300MY SG carries the SG suffix that Mazak attaches to every model on its QTE series list, from the QTE-100 SG to the QTE-200MSY SG. That list ends at the 200 size, however. A 300 does not appear on it, so what follows describes the listed figures for a Y-axis milling lathe one size up, and Mazak should be asked to confirm them.

The listed envelope is 620 mm (24.4 in) of swing over the bed, 230 mm (9.06 in) of X travel and 620 mm (24.41 in) of Z travel. Set beside the QTE-200M table, which shows 9 in (229 mm) of X and 24 in (610 mm) of Z, the travels are nearly the same. The listed difference is at the spindle: 4,000 RPM against the 5,000 rpm of the QTE-200M, with an A2-8 nose, 80 mm (3.15 in) bar capacity and 22 kW (30 hp) listed.

The turret is listed as a live tooling turret with Y-axis: twelve stations, rotary tools at 6,000 RPM and 5.5 kW (7.4 hp), and Y travel of 100 mm (±50 mm) moving at 10 m/min (394 ipm) in rapid. C-axis resolution is listed at 0.0001 degrees. Mazak says the drum turrets of the series use non-lift rotary indexing and a 25 mm × 25 mm tool shank.

Programming is on MAZATROL SmoothEz, which Mazak describes as having touch-panel program creation at the machine and a digital setup function that replicates the machine on an office PC. Loading can be automated with the optional Ez LOADER or gantry loader. Listed machine weight is 5,600 kg (12,346 lb).

Strengths & Limitations

Strengths

Travels listed at 230 mm (9.06 in) in X and 620 mm (24.41 in) in Z, close to the 9 in (229 mm) and 24 in (610 mm) of the QTE-200M table
A2-8 spindle nose with a listed 80 mm (3.15 in) bar capacity
Live tooling turret with Y-axis: 12 stations and a listed 100 mm (±50 mm) of Y travel
MAZATROL SmoothEz control, with the digital setup function Mazak describes for the series

Limitations

Mazak's QTE list ends at the QTE-200MSY SG; no 300 size is named on it
Listed main spindle speed of 4,000 RPM, below the 5,000 rpm shown for the QTE-200M
Single spindle: nothing in the listed figures provides for back-face machining
Ez LOADER and gantry loader automation are options in the series and not standard equipment

Best For

Turn-mill parts with Y-axis features inside the listed 100 mm stroke Bar work up to the listed 80 mm (3.15 in) Shafts within 620 mm (24.41 in) of listed Z travel Cells built around the optional gantry loader of the QTE series

Frequently Asked Questions

01 Which QTE models does Mazak list with the SG suffix?

All eight on its QTE series list: 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. The QTE-300MY SG is not one of them, so its availability and specification should be confirmed with Mazak.

02 How do the listed travels compare with the 200-size machines?

Listed travels are 230 mm (9.06 in) in X and 620 mm (24.41 in) in Z. The QTE-200M table shows 9 in (229 mm) and 24 in (610 mm), so the working strokes are almost equal. Listed rapids of 30 m/min (1,181 ipm) on X and Z also match the QTE-200M.

03 What tooling does the turret take?

The listed turret has 12 stations with live tooling and a Y-axis, and rotary tools are listed at 6,000 RPM and 5.5 kW (7.4 hp). For the QTE series Mazak states that 8 and 12 position drum turrets are available, with non-lift rotary indexing and a 25 mm × 25 mm tool shank.

04 Which control does the QTE-300MY SG use?

MAZATROL SmoothEz, the control Mazak names for the QTE series. Mazak says programs can be created at the machine with touch-panel controls while checking the workpiece shape and process, and that the digital setup function can replicate the machine on a PC in the office to cut down on-machine setup work.
