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 450MY is a long-bed, 18 in chuck turning center with milling and a Y-axis: 80 in (2,032 mm) of maximum turning length, Ø24 in (610 mm) of turning diameter and 84 in (2,134 mm) of Z travel. Mazak's model list gives the configuration as Milling, Y-axis, VDI.

The spindle is slow and wide by design. It tops out at 2,000 rpm, is rated 37 kW (50 HP) on a 30 min. rating, and has Ø7 in (178 mm) of bar capacity. At the diameters this machine is meant for, 2,000 rpm is ample surface speed; on a small journal at the end of a long shaft it is not, and finishing passes there will run below the speed carbide prefers. The bore matters as much as the power, because it lets long tube and heavy bar pass through the spindle instead of hanging entirely between chuck and tailstock.

Y travel is 8 in (203 mm) and X is 13 in (330 mm) under a Ø33 in (838 mm) swing. On a part this long, the Y-axis earns its place with keyways, wrench flats and offset drilling done while the shaft is still supported, which avoids rigging a multi-metre part onto a second machine. Mazak groups the model with the 18 / 21 inch chuck sizes and gives that group a Ø50 boring bar shank and a 32 mm turning tool shank. The turret holds 12 tools.

What the length adds shows against the QUICK TURN 450M, which lists 42 in (1,067 mm) of Z, Ø23 in (584 mm) of turning diameter and 14 in (356 mm) of X on the same 18 in chuck and 2,000 rpm spindle. Mazak's table for the 450MY gives no machine weight, floor space or tailstock row, and all three are needed before a machine of this length can be planned into a building.

Strengths & Limitations

Strengths

80 in (2,032 mm) of maximum turning length with 84 in (2,134 mm) of Z travel
Bar capacity of Ø7 in (178 mm) through an 18 in chuck spindle
Y-axis travel of 8 in (203 mm) for keyways, flats and offset holes on long parts
Main spindle rated 37 kW (50 HP) on a 30 min. rating
Turning diameter of Ø24 in (610 mm) under a Ø33 in (838 mm) swing

Limitations

Spindle speed is limited to 2,000 rpm, which holds back surface speed on small diameters
No second spindle in Mazak's configuration, so both ends of a shaft mean turning the part around
Only 12 tools for turning, boring and milling on parts with many features along 80 in (2,032 mm)
Mazak's table gives no weight, floor space or tailstock data for planning the installation

Best For

Shafts and rolls up to 80 in (2,032 mm) long and Ø24 in (610 mm) in diameter Tube and heavy bar within the Ø7 in (178 mm) bar capacity Long parts needing keyways or flats cut with 8 in (203 mm) of Y travel Large-diameter roughing with 37 kW (50 HP) on a 30 min. rating

Frequently Asked Questions

01 How long and how large a workpiece does the Quick Turn 450MY take?

Maximum turning length is 80 in (2,032 mm) and maximum turning diameter is Ø24 in (610 mm), under a Ø33 in (838 mm) swing. Z travel is 84 in (2,134 mm) and Mazak gives the bed-length class as 80 in (2,032 mm). Bar capacity is Ø7 in (178 mm).

02 Why is the spindle limited to 2,000 rpm?

The table lists 2,000 rpm for the 18 in chuck spindle, the same figure as on the QUICK TURN 450M. A large chuck and a Ø7 in (178 mm) bar capacity go with a low top speed. For work near the Ø24 in (610 mm) limit that is no handicap; for small diameters it restricts cutting speed, so check the smallest diameter you intend to finish.

03 What chuck does the Quick Turn 450MY use?

The table lists an 18 in chuck. On Mazak's series page the model sits in the 18 / 21 inch chuck group, which carries a 37 kW (50 HP) spindle, a Ø50 boring bar shank and a 32 mm turning tool shank. If a 21 inch chuck is wanted, raise it at the quotation stage.

04 How does it compare with the QUICK TURN 450M?

The QUICK TURN 450M has the same 18 in chuck, 2,000 rpm, Ø33 in (838 mm) swing and 12 tools, with 42 in (1,067 mm) of Z travel, Ø23 in (584 mm) of turning diameter and 14 in (356 mm) of X. The 450MY covered here has 84 in (2,134 mm) of Z and adds a Y-axis with 8 in (203 mm) of travel.

05 Is a tailstock or steady rest included?

The model's table does not list either. For the series Mazak describes an NC tailstock whose thrust is set in 0.1 kN increments, in dead-center type for light-duty work or built-in-center type for heavy-duty cutting, together with a steady rest. On an 80 in (2,032 mm) machine both should be specified in the quotation.
