How much does the Mazak QT-Ez 10MSY 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 10MSY puts a second spindle and a Y-axis on the 10 in chuck QT-Ez turning center. The main spindle runs to 4,200 rpm on a motor rated 15 kW (20 HP) (30 min. rating). The second spindle has a 6 in chuck, runs to 6,000 rpm and is rated 8 kW (10 HP) (30 min. rating).
The layout exists to finish both ends of a part without an operator turning it around. The first side is cut in the 10 in chuck, the part is handed across, and the back is machined in the second spindle while it is still on the machine. W-axis travel is 23 in (584 mm), which on a two-spindle lathe is the stroke that brings the second spindle up to the main chuck for the handover.
The two spindles are not equals, and the process should be planned around that. On the same 30 min. basis the second spindle's 8 kW (10 HP) is a little over half the main motor's 15 kW (20 HP), and its chuck is 6 in against 10 in. Heavy stock removal belongs on the first side. The second spindle is for facing, finishing and whatever the first clamping could not reach, and whatever is handed over has to be a diameter a 6 in chuck can grip.
Y travel is 4 in (102 mm), X travel 9 in (229 mm) and Z travel 24 in (610 mm). The turning envelope is Ø14 in (356 mm) by 22 in (559 mm) with Ø3 in (76 mm) bar capacity, so bar-fed parts can go in as stock and leave complete. The QT-Ez 10MY lists the same Y travel with a 20 in (508 mm) turning length.
Two things are absent from Mazak's table for this model: a tool capacity figure and any rotary-tool speed or power. Both shape what can be done in one cycle, so obtain them from Mazak. The series equipment list includes high/low chuck pressure switching, which is worth asking about for parts gripped on a finished diameter.

Strengths & Limitations
Strengths
- Second spindle with a 6 in chuck, 6,000 rpm and 8 kW (10 HP) (30 min. rating) for back-end machining in the same cycle
- W-axis travel of 23 in (584 mm) for part transfer between spindles
- Y travel of 4 in (102 mm) alongside 9 in (229 mm) X and 24 in (610 mm) Z
- Main spindle rated 15 kW (20 HP) (30 min. rating) at up to 4,200 rpm with a 10 in chuck
- 22 in (559 mm) turning length, longer than the 20 in (508 mm) of the QT-Ez 10M and QT-Ez 10MY
Limitations
- Second spindle motor is 8 kW (10 HP) (30 min. rating), a little over half the main spindle's rating, so heavy cuts must be done on the first side
- Parts handed to the second spindle must fit a 6 in chuck
- Mazak's table lists no tool capacity and no rotary-tool speed or power for this model
- Turning diameter is Ø14 in (356 mm), against Ø16 in (406 mm) on the QT-Ez 10

Frequently Asked Questions
01
A 6 in chuck, a top speed of 6,000 rpm and a motor rated 8 kW (10 HP) (30 min. rating). The W-axis travel listed with it is 23 in (584 mm). The main spindle has a 10 in chuck, runs to 4,200 rpm and is rated 15 kW (20 HP) (30 min. rating).
02
The QT-Ez 12MSY has a 12 in main chuck, a 3,300 rpm main spindle rated 22 kW (30 HP) (30 min. rating) and a second spindle rated 11 kW (15 HP) (30 min. rating). The QT-Ez 10MSY has a 10 in chuck, 4,200 rpm, 15 kW (20 HP) (30 min. rating) and an 8 kW (10 HP) (30 min. rating) second spindle. Both second spindles have a 6 in chuck and run to 6,000 rpm.
03
The table supports it: Ø3 in (76 mm) bar capacity, a second spindle to take the part for back-end work, and 4 in (102 mm) of Y travel. What the table does not give is the tool capacity or the rotary-tool figures, so check that the turret can hold the tools for both sides of the part.
04
Maximum turning diameter is Ø14 in (356 mm) and maximum turning length 22 in (559 mm), with a swing of Ø27 in (686 mm). Travels are 9 in (229 mm) in X, 4 in (102 mm) in Y and 24 in (610 mm) in Z, plus 23 in (584 mm) on the W-axis.
