Overview

The Mazak QT-Ez series is a family of twelve turning centers built on one platform: a Ø27 in (686 mm) swing, 9 in (229 mm) of X travel and a 12-tool turret on every model. What changes from one to the next is the chuck, from 8 in to 12 in, and the letters after the number.

The number is the chuck size. The QT-Ez 10 has a 10 in chuck, turns Ø16 in (406 mm) by 23 in (584 mm) and runs to 4,500 rpm on 25 in (635 mm) of Z travel. The QT-Ez 12 has a 12 in chuck, the same Ø16 in (406 mm) diameter and Z travel, 21 in (533 mm) of turning length and a 4,000 rpm spindle. Across the series, top speed runs from 3,300 rpm to 6,000 rpm, bar capacity from Ø2 in (51 mm) to Ø3 in (76 mm) and spindle power from 15 kW (20 HP) to 22 kW (30 HP) on a 30 min. rating.

Each chuck size comes as a plain model and as M, MY and MSY models. Mazak's model list does not spell the letters out, so go by what the rows show. The QT-Ez 10M turns Ø14 in (356 mm) by 20 in (508 mm) at 4,200 rpm with 24 in (610 mm) of Z, a smaller envelope than the plain QT-Ez 10. The QT-Ez 10MY adds 4 in (102 mm) of Y travel to those figures. The QT-Ez 10MSY has the same Y travel and a turning length of 22 in (559 mm). The table has no further rows that tell the variants apart, so ask Mazak exactly what each suffix adds before comparing models.

Mazak's series page names a set of equipment for the QT-Ez: automatic tool eye, high/low chuck pressure switching, automatic door, extra work light, 3-color signal tower, chip conveyor, air hose prep, coolant system, an additional head-side coolant nozzle, mist collector, Mazak SUPERFLOW 1000 psi high-pressure coolant and coolant temperature control. The page does not mark which are standard and which are options, so have each one itemised on the quotation.

Strengths & Limitations

Strengths

One platform for twelve models: Ø27 in (686 mm) swing, 9 in (229 mm) of X and a 12-tool turret throughout
Chuck sizes from 8 in to 12 in with bar capacity from Ø2 in (51 mm) to Ø3 in (76 mm)
Spindle power of 15 kW (20 HP) to 22 kW (30 HP) on a 30 min. rating, with top speeds from 3,300 rpm to 6,000 rpm
MY and MSY models carry 4 in (102 mm) of Y travel
Mazak SUPERFLOW 1000 psi high-pressure coolant, automatic tool eye and automatic door are named for the series

Limitations

The table gives spindle power on a 30 min. rating only; no continuous rating or torque figure is listed
The QT-Ez 10M turns Ø14 in (356 mm) against Ø16 in (406 mm) on the QT-Ez 10, so the suffixed models have the smaller envelope
Turning length stops at 23 in (584 mm) and X travel at 9 in (229 mm) on every model
Mazak's equipment list does not say which items are standard and which are options
No rapid traverse, weight or floor-space figures are listed for the series

Best For

General chuck and bar turning with 8 in to 12 in chucks Bar work up to Ø3 in (76 mm) on the larger models Parts within Ø16 in (406 mm) by 23 in (584 mm) on the plain models Shops standardising on one platform across several chuck sizes Turned parts needing off-centre features, on the models with 4 in (102 mm) of Y

Frequently Asked Questions

01 Which models are in the QT-Ez series?

Twelve: the QT-Ez 8, QT-Ez 10 and QT-Ez 12, each as a plain model and as M, MY and MSY models. All share a Ø27 in (686 mm) swing, 9 in (229 mm) of X travel and a 12-tool turret. Chuck sizes run from 8 in to 12 in and Z travel from 24 in (610 mm) to 25 in (635 mm).

02 How does the QT-Ez 10 differ from the QT-Ez 12?

The QT-Ez 10 has a 10 in chuck, a 4,500 rpm spindle and 23 in (584 mm) of turning length. The QT-Ez 12 has a 12 in chuck, a 4,000 rpm spindle and 21 in (533 mm) of turning length. Both turn Ø16 in (406 mm) with 9 in (229 mm) of X and 25 in (635 mm) of Z, and both carry 12 tools.

03 Which QT-Ez models have a Y axis?

The table shows Y travel of 4 in (102 mm), and among the 10 in machines it appears on the QT-Ez 10MY and the QT-Ez 10MSY. The plain QT-Ez 10 and the QT-Ez 10M list no Y travel. The 8 in and 12 in sizes repeat the same four model names.

04 How much turning capacity is lost on the suffixed QT-Ez models?

In the 10 in size, the plain QT-Ez 10 turns Ø16 in (406 mm) by 23 in (584 mm) with 25 in (635 mm) of Z. The QT-Ez 10M turns Ø14 in (356 mm) by 20 in (508 mm) with 24 in (610 mm) of Z and a 4,200 rpm spindle. The QT-Ez 10MSY turns Ø14 in (356 mm) by 22 in (559 mm).

05 What equipment does Mazak list for the QT-Ez?

Automatic tool eye, high/low chuck pressure switching, automatic door, extra work light, 3-color signal tower, chip conveyor, air hose prep, coolant system, additional head-side coolant nozzle, mist collector, Mazak SUPERFLOW 1000 psi high-pressure coolant and coolant temperature control. The series page does not say which are standard, so confirm each on the quotation.
