Overview
The Mazak Quick Turn 250MSY is the 10 in chuck Quick Turn with everything fitted: Mazak's model list gives it milling, a second spindle, a Y-axis and a VDI turret. The main spindle turns at up to 4,000 rpm with 26 kW (35 HP) on a 30 min. rating. Facing it is a 6 in second spindle that reaches 6,000 rpm with 11 kW (15 HP) on the same 30 min. rating.
The envelope is short and stout. Maximum turning diameter is Ø15 in (381 mm) under a Ø27 in (686 mm) swing, maximum turning length is 21 in (533 mm), and bar capacity through the main spindle is Ø3 in (76 mm). X travel is 9 in (229 mm) and Z is 23 in (584 mm). The W axis, the one a second spindle normally rides on, has the same 23 in (584 mm), so the pick-off is not what limits part length.
The two spindles are not equals. The second one has well under half the main spindle's power on the same rating and a 6 in chuck against 10 in, so heavy roughing belongs in the first operation. The second side is for finishing, back-facing, drilling and the milled features that could not be reached before the transfer. Its higher speed helps there, because second-side work tends to sit on smaller diameters.
Y travel is 4 in (102 mm), enough for off-centre holes, flats and keyways on parts of this size, and all of the work has to be served from 12 tools. A turret that carries turning tools for two spindles plus live tools fills quickly, so count stations before assuming a job runs complete. For the series, Mazak states C-axis indexing in 0.0001° increments as standard on the main and the second spindle; contouring is optional, and standard on the main spindle of M models.

Strengths & Limitations
Strengths
- Two spindles in one machine: a 10 in chuck at 4,000 rpm and 26 kW (35 HP) (30 min. rating), and a 6 in chuck at 6,000 rpm and 11 kW (15 HP) (30 min. rating)
- W-axis travel of 23 in (584 mm) equals the Z travel and exceeds the 21 in (533 mm) maximum turning length
- Y-axis with 4 in (102 mm) of travel, listed by Mazak together with milling and a VDI turret
- Bar capacity of Ø3 in (76 mm) through the main spindle, for bar-fed parts finished on both ends
- C-axis indexing in 0.0001° increments is standard on the main and second spindle in this series
Limitations
- The second spindle is rated 11 kW (15 HP) (30 min. rating) with a 6 in chuck, so second-side cuts have to be lighter than first-side cuts
- 12 tools serve two spindles and the milling work; parts with many features can run out of stations
- The main spindle stops at 4,000 rpm, where the 8 in chuck Quick Turn 200MSY reaches 5,000 rpm on the same Ø15 in (381 mm) turning diameter
- Y travel is 4 in (102 mm) in total, which limits how far off centre a milled feature can sit
- C-axis contouring on the second spindle and scale feedback on X and Z are options in the series

Frequently Asked Questions
01
Mazak's model list describes the configuration as Milling, Second Spindle, Y-axis, VDI. In the table that shows up as a 6 in second spindle running to 6,000 rpm, 4 in (102 mm) of Y travel and a 12-tool turret. VDI is the tool-holder interface; in the series the tool holder can be bolt-on or VDI.
02
The main spindle carries a 10 in chuck, runs to 4,000 rpm and is rated 26 kW (35 HP) on a 30 min. rating. The second spindle carries a 6 in chuck, runs to 6,000 rpm and is rated 11 kW (15 HP) on a 30 min. rating. Plan the heavy stock removal for the main spindle and use the second for finishing and back-end features.
03
Maximum turning diameter is Ø15 in (381 mm), maximum turning length is 21 in (533 mm) and the swing is Ø27 in (686 mm). Bar work is limited to Ø3 in (76 mm). Travels are 9 in (229 mm) in X, 4 in (102 mm) in Y and 23 in (584 mm) in both Z and W.
04
The Quick Turn 250M has the same 10 in chuck, 4,000 rpm main spindle, Ø27 in (686 mm) swing and 12 tools, with a turning length of 20 in (508 mm) and 22 in (559 mm) of Z travel. The 250MSY adds the 6 in second spindle on a 23 in (584 mm) W axis and 4 in (102 mm) of Y travel, so a part can be transferred and its back end machined without a second setup.
05
For the Quick Turn series Mazak states that C-axis positioning in 0.0001° minimum increments is standard equipment on the main spindle and the second spindle. Contouring is optionally available, and is standard for the main spindle of M models. If the second-side work needs contouring, have it written into the quotation.
