How much does the Mazak QT-Ez 10 cost?
Estimated price range
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
The Mazak QT-Ez 10 is a two-axis turning center with a 10 in chuck, a 4,500 rpm spindle and Ø3 in (76 mm) bar capacity. It turns up to Ø16 in (406 mm) in diameter over 23 in (584 mm) of length and carries 12 tools. That is a larger turning envelope than the QT-Ez 10M, QT-Ez 10MY or QT-Ez 10MSY list.
Its figures sit between those of its neighbours. The QT-Ez 8 spins to 6,000 rpm but passes only Ø2 in (51 mm) bar. The QT-Ez 12 brings a 12 in chuck and a 22 kW (30 HP) (30 min. rating) motor but tops out at 4,000 rpm and turns 21 in (533 mm) in length. The QT-Ez 10 matches the bar capacity of the larger machine and keeps a spindle motor of 15 kW (20 HP) (30 min. rating), the rating the QT-Ez 8 also carries.
Axis travel is 9 in (229 mm) in X and 25 in (635 mm) in Z, under a swing of Ø27 in (686 mm). The 23 in (584 mm) turning length compares with 20 in (508 mm) on the QT-Ez 10M and QT-Ez 10MY, so parts near the long end of the range are a reason to stay with this model.
The table lists X and Z only. If a part needs work off the centreline or a finished back end in the same cycle, the rows to look at are on other models: the QT-Ez 10MY lists 4 in (102 mm) of Y travel, and the QT-Ez 10MSY lists a second spindle with a 6 in chuck. On the plain QT-Ez 10 such features mean a second operation.
Mazak's series page lists an automatic tool eye, high/low chuck pressure switching, an automatic door and a chip conveyor among the QT-Ez equipment, without saying which are part of the base machine. Have the quotation state each item.

Strengths & Limitations
Strengths
- Ø16 in (406 mm) by 23 in (584 mm) turning envelope, against the Ø14 in (356 mm) turning diameter of the QT-Ez 10M, QT-Ez 10MY and QT-Ez 10MSY
- Ø3 in (76 mm) bar capacity, against Ø2 in (51 mm) on the QT-Ez 8
- 4,500 rpm spindle with a 15 kW (20 HP) (30 min. rating) motor
- 12 tools in the turret and 25 in (635 mm) of Z travel
Limitations
- X and Z axes only: no Y-axis, rotary-tool or second-spindle rows in the table, so milled features and back-end work need another setup
- Top speed is 4,500 rpm where the QT-Ez 8 reaches 6,000 rpm, which matters on small-diameter bar
- Motor is 15 kW (20 HP) (30 min. rating); the QT-Ez 12 lists 22 kW (30 HP) (30 min. rating) for heavier cuts
- No continuous power or torque figure is given for the spindle

Frequently Asked Questions
01
Maximum turning diameter is Ø16 in (406 mm) and maximum turning length 23 in (584 mm), with a swing of Ø27 in (686 mm). X travel is 9 in (229 mm), Z travel 25 in (635 mm), and the spindle passes bar up to Ø3 in (76 mm).
02
Both turn Ø16 in (406 mm) and pass Ø3 in (76 mm) bar. The QT-Ez 12 has a 12 in chuck and a 22 kW (30 HP) (30 min. rating) motor, with a 4,000 rpm top speed and 21 in (533 mm) turning length. The QT-Ez 10 has a 10 in chuck, 15 kW (20 HP) (30 min. rating), 4,500 rpm and 23 in (584 mm). Pick the QT-Ez 12 for heavier cuts and larger blanks, the QT-Ez 10 for speed and length.
03
Spindle speed: 4,500 rpm against 6,000 rpm on the QT-Ez 8. In return it has a 10 in chuck in place of the 8 in chuck of the QT-Ez 8 and passes Ø3 in (76 mm) bar where the QT-Ez 8 passes Ø2 in (51 mm). The turning envelope and the 15 kW (20 HP) (30 min. rating) motor are the same.
04
No such rows appear in Mazak's table for the QT-Ez 10, which lists X and Z travel only. The QT-Ez 10MY lists Y travel of 4 in (102 mm). The QT-Ez 10MSY lists the same Y travel plus a second spindle with a 6 in chuck. The QT-Ez 10MY and QT-Ez 10MSY both turn a smaller diameter, Ø14 in (356 mm).
05
The spindle motor is listed at 15 kW (20 HP) (30 min. rating) and the top speed is 4,500 rpm. Mazak's table does not give a continuous rating or a torque figure. For long roughing cuts, size the job to the continuous output, which has to be requested from Mazak.
