Overview

The Mazak Quick Turn Nexus 450MY is a heavy turn-mill lathe: an 18 in chuck on an A2-11 nose, a 2,000 RPM spindle, a milling spindle listed at 4,500 RPM and a Y-axis of ±80 mm (±3.15 in). It is not in Mazak's current lineup, and the table on this page is a listed table, part of it from a QUICK TURN 450MY-80 listing. Read it as a guide to an existing machine, not as a specification.

Length is the row to settle first, because the table holds two answers. Maximum turning length is listed as 1,524 mm (60 in) with 1,570 mm (61.8 in) of Z travel, while the 450MY-80 rows give a machining length of 80.31 in. The same happens on a smaller scale with diameter, 600 mm (23.62 in) in one row and 23.83 in in another. The two sets of rows cannot both describe one bed, so measure the machine you are looking at.

The spindle figures are consistent. Power is listed at 37 kW (50 hp) at 25% ED and 22 kW (30 hp) continuous, with 2,450 Nm (1,807 ft-lb) of torque at 25% ED. Bar capacity is listed at 7.2 in, a large bore that takes heavy tube and pipe through the spindle. X travel is 350 mm (13.78 in) and the swing over the bed is listed at 33.07 in.

The turret has 12 positions with the VDI 60 interface, a size of holder matched to the cutting forces involved. Rapids are listed at 25 m/min (984 ipm) in X and 30 m/min (1,181 ipm) in Z, a tailstock is listed, and the weight is given as 14,500 kg (31,967 lb). Mazak's present Quick Turn 450MY, for comparison, has an 18 in chuck, 2,000 rpm, 8 in (203 mm) of Y travel and 80 in (2,032 mm) of turning length.

Strengths & Limitations

Strengths

Listed bar capacity of 7.2 in through an 18 in chuck spindle
Listed torque of 2,450 Nm (1,807 ft-lb) at 25% ED, with 37 kW (50 hp) at 25% ED and 22 kW (30 hp) continuous
Y-axis listed at ±80 mm (±3.15 in) with a 4,500 RPM milling spindle
Turret of 12 positions with the VDI 60 interface
A tailstock is listed, for shaft work over the long bed

Limitations

Not in Mazak's current lineup, so there is no current Mazak table to confirm the listed figures
The table gives two lengths, 1,524 mm (60 in) of turning length and 80.31 in of machining length
Spindle speed is listed at 2,000 RPM maximum
No power or torque is listed for the milling spindle
Listed weight of 14,500 kg (31,967 lb) makes moving and foundations a real part of the purchase

Best For

Long, heavy shafts with keyways or flats milled within ±80 mm (±3.15 in) of Y Tube and pipe work within the listed 7.2 in bar capacity Large-diameter turning to the listed 600 mm (23.62 in) Buyers assessing an existing machine against listed figures

Frequently Asked Questions

01 How long a part does the Quick Turn Nexus 450MY turn?

The table is not consistent on this. One row lists a maximum turning length of 1,524 mm (60 in) with 1,570 mm (61.8 in) of Z travel; the rows for the QUICK TURN 450MY-80 list a machining length of 80.31 in. Treat the bed length as unknown until it has been measured or read from the machine's documents.

02 Is the Quick Turn Nexus 450MY the same as the current Quick Turn 450MY?

It is not in Mazak's current lineup under the Nexus name. Mazak's table for the present Quick Turn 450MY gives an 18 in chuck, 2,000 rpm, Ø24 in (610 mm) of turning diameter, 80 in (2,032 mm) of turning length and 8 in (203 mm) of Y travel. The listed Nexus machine is similar in size, but the tables should not be mixed.

03 What are the listed spindle ratings?

37 kW (50 hp) at 25% ED and 22 kW (30 hp) continuous, with 2,450 Nm (1,807 ft-lb) of torque at 25% ED and a 2,000 RPM maximum on an A2-11 nose. For long roughing cuts plan with the continuous figure. The milling spindle is listed at 4,500 RPM with no power figure.

04 What does the Y-axis offer on a machine this size?

The listed Y-axis is ±80 mm (±3.15 in). On long shafts that allows keyways, wrench flats and offset holes to be cut while the part is still held between chuck and tailstock, which saves moving a heavy part to a second machine.

05 How does it differ from the Quick Turn Nexus 550-II?

The Quick Turn Nexus 550-II is listed as a larger machine without the 450MY's Y-axis rows: 830 mm (32.68 in) of turning diameter, a 610 mm (24 in) chuck, 1,500 RPM, 4,800 Nm (3,540 ft-lb) at 25% ED and 22,000 kg (48,502 lb). The 450MY is listed at 14,500 kg (31,967 lb) with a 2,000 RPM spindle.
