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 Nexus 250MY is listed as a 254 mm (10 in) chuck turning center with a milling turret and a Y-axis of ±52.5 mm (±2.07 in), offered in two bed lengths. The figures below are listed figures. The Nexus name is not on Mazak's QUICK TURN model list, which in this size has the QUICK TURN 250MY (Milling, Y-axis, VDI), so a quotation or the machine's own plate should settle anything that matters.

The two beds are the main choice. The standard bed is listed with 510 mm (20.08 in) of turning length and 560 mm (22.05 in) of Z travel; the long bed with 1,011 mm (39.8 in) and 1,060 mm. Maximum turning diameter is listed at 366 mm (14.41 in) under a 580 mm (22.8 in) swing on either, with 215 mm (8.46 in) of X travel. A chucking shop and a shaft shop would order different machines under this one name.

The spindle rows are more complete than on most listed tables. Power is given as 22 kW (30 hp) at 25% ED and 15 kW (20 hp) continuous, torque as 626 Nm (462 ft-lb) at 25% ED, and top speed as 4,500 RPM on an A2-6 nose. The gap between the two power figures matters on long roughing passes, which is exactly what the long bed invites: size those cuts on the continuous 15 kW (20 hp). Bar capacity is listed at 65 mm (2.56 in).

Milling is listed at 6,000 RPM from a turret of 12 positions (VDI 40), with no power or torque figure for the live tools. Rapids are listed at 30 m/min (1,181 ipm) in X and Z, the weight at 6,500 kg (14,330 lb) and the control as MAZATROL SmoothG CNC, the control Mazak describes for the series.

Strengths & Limitations

Strengths

Listed in two bed lengths: 510 mm (20.08 in) or 1,011 mm (39.8 in) of turning length
Spindle power listed with both ratings: 22 kW (30 hp) at 25% ED and 15 kW (20 hp) continuous
Listed torque of 626 Nm (462 ft-lb) at 25% ED with a 4,500 RPM maximum
Y-axis listed at ±52.5 mm (±2.07 in) with a 6,000 RPM milling spindle
Turret of 12 positions listed with the VDI 40 interface

Limitations

The Nexus name is not on Mazak's model list, which shows a QUICK TURN 250MY (Milling, Y-axis, VDI) in this size
Continuous spindle power is listed at 15 kW (20 hp); the 22 kW (30 hp) figure applies only at 25% ED
No power or torque is listed for the 6,000 RPM milling spindle
No second-spindle row, so back-end work needs another setup

Frequently Asked Questions

01 What are the two bed lengths of the Quick Turn Nexus 250MY?

The table lists a maximum turning length of 510 mm (20.08 in) on the standard bed and 1,011 mm (39.8 in) on the long bed, with Z travel of 560 mm (22.05 in) and 1,060 mm respectively. Turning diameter, 366 mm (14.41 in), and X travel, 215 mm (8.46 in), are listed once for both.

02 Which spindle power figure should I plan with?

The listed 22 kW (30 hp) and 626 Nm (462 ft-lb) are at 25% ED, a short-duty rating. The continuous figure is 15 kW (20 hp). For long roughing cuts, as on a shaft filling the long bed, work from the continuous figure and treat the 25% ED rating as a reserve for brief heavy cuts.

03 How much Y-axis travel is listed?

±52.5 mm (±2.07 in) about the spindle centreline. With the 6,000 RPM milling spindle that covers keyways, flats and offset holes on parts within the 366 mm (14.41 in) turning diameter. The table lists no power for the milling spindle, so ask for it if the milling is more than light work.

04 Is this the same machine as the QUICK TURN 250MY?

Mazak's model list has a QUICK TURN 250MY, configured as Milling, Y-axis, VDI, and no model with Nexus in the name. The listed Nexus 250MY table shows the same kind of build, a milling turret with a Y-axis and VDI 40 holders, but it should not be assumed that every figure carries over. Compare the two tables row by row.
