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 QUICK TURN 250MY is the long way to buy a 10 in chuck Quick Turn with a Y-axis: maximum turning length is 40 in (1,016 mm) and Z travel 43 in (1,092 mm), on a machine whose maximum turning diameter is Ø15 in (381 mm). Mazak's model list configures it as Milling, Y-axis, VDI, with no second spindle.

That ratio of length to diameter defines the work. A part that uses the full 40 in (1,016 mm) is a shaft, and a shaft that slender needs support at the free end. For the series Mazak describes an NC tailstock driven by ball screw and servo motor, with thrust set in 0.1 kN increments and a choice of dead-center or built-in-center type, along with a steady rest. The table for the 250MY does not say which of these the machine carries. It does list a W-axis travel of 42 in (1,067 mm), nearly the whole Z stroke, so ask what rides on that axis in the build you are quoted.

The spindle is no bigger for the extra length: 4,000 rpm maximum, 26 kW (35 HP) on a 30 min. rating, and Ø3 in (76 mm) of bar capacity. X travel is 9 in (229 mm) under a Ø27 in (686 mm) swing. The Y-axis has 4 in (102 mm) of travel, which is what puts keyways, flats and cross holes off the centreline onto a shaft without moving it to a mill. The turret holds 12 tools.

One row needs a question before ordering. The bed-length class in Mazak's table reads 20 in (508 mm), which does not agree with a 40 in (1,016 mm) turning length. Settle the bed length on the quotation, not from the web table.

Strengths & Limitations

Strengths

40 in (1,016 mm) of maximum turning length and 43 in (1,092 mm) of Z travel on a 10 in chuck machine
Y-axis travel of 4 in (102 mm) with milling, so keyways and off-centre holes are cut in the turning setup
W-axis travel of 42 in (1,067 mm), close to the full Z stroke
Main spindle rated 26 kW (35 HP) (30 min. rating) at up to 4,000 rpm, with Ø3 in (76 mm) bar capacity
Built-in motor spindle with no gears or belts, which Mazak fits to all models of the series

Limitations

Mazak's configuration of the 250MY has no second spindle, so the back of a part needs a second setup
Maximum turning diameter stays at Ø15 in (381 mm) however long the bed is; the added capacity is all in length
12 tools have to cover turning, boring and live tooling on long parts with many features
The bed-length class of 20 in (508 mm) in the table conflicts with the 40 in (1,016 mm) turning length and must be confirmed
Scale feedback on X and Z is an option in the series, not standard equipment

Best For

Shafts up to 40 in (1,016 mm) long with keyways or cross holes Long bar-type parts within the Ø3 in (76 mm) bar capacity Chuck work to Ø15 in (381 mm) that needs off-centre milling End-supported parts turned and milled without a transfer to a mill

Frequently Asked Questions

01 How long a part can the QUICK TURN 250MY turn?

Mazak lists a maximum turning length of 40 in (1,016 mm) with 43 in (1,092 mm) of Z travel. Maximum turning diameter is Ø15 in (381 mm) and the swing is Ø27 in (686 mm). The same table gives the bed-length class as 20 in (508 mm), which does not match the turning length, so confirm the bed with Mazak before relying on either figure.

02 Does the QUICK TURN 250MY come with a tailstock?

The model's table has no tailstock row. It lists a W-axis travel of 42 in (1,067 mm), and for the series Mazak describes an NC tailstock with ball screw and servo motor drive whose thrust is set in 0.1 kN increments, in dead-center or built-in-center type. Have the tailstock type and any steady rest stated in the quotation.

03 What is the difference between the QUICK TURN 250MY and the Quick Turn 250M?

The Quick Turn 250M shares the 10 in chuck, the 4,000 rpm spindle and the Ø15 in (381 mm) turning diameter, with a turning length of 20 in (508 mm) and 22 in (559 mm) of Z travel. The 250MY described here turns twice that length and adds 4 in (102 mm) of Y travel for off-centre milling.

04 How much Y-axis travel is there, and what does it allow?

Y travel is 4 in (102 mm). With live tools in the turret that is what lets the machine cut a keyway with parallel walls, drill a hole off the centreline or mill a flat at a set distance from centre. Features that sit further off centre than the stroke allows are outside the machine.

05 What spindle does the QUICK TURN 250MY have?

A 10 in chuck spindle with a 4,000 rpm maximum, rated 26 kW (35 HP) on a 30 min. rating, with Ø3 in (76 mm) of bar capacity. Mazak states that every model of the series has a built-in motor spindle, which has no gears or belts.
