Frequently asked questions

Specifications and capacity
Q: What are its maximum dimensions?
A: Φ420 mm maximum swing and machining diameter, Φ126 mm over the toolholder and 270 mm maximum machining length.
Q: What bar size can it accept?
A: Maximum bar capacity is Φ46 mm; spindle bore is Φ56 mm, with a 6-inch hydraulic collet.
Q: What is the spindle output?
A: Up to 4,500 rpm, with a 7.5 kW motor and 35 N·m maximum torque.

Machine selection
Q: Gang-tool or turret lathe?
A: Gang tooling changes tools quickly and suits repeated operations on batch parts. A turret has more tool positions for complex multi-operation work. Select according to the number of operations and production volume.
Q: QPR-46L or QPR-36L?
A: The 46L offers Φ420 mm capacity, Φ46 mm bar capacity and a 7.5 kW/35 N·m spindle for larger or heavier work. The 36L is more compact and economical for smaller parts.

Production and service
Q: Can it use an automatic bar feeder?
A: Yes. A feeder can support continuous production with Φ46 mm bar capacity.
Q: What parts suit it?
A: Precision shafts and discs, automotive components and construction machinery parts.
Q: How is accuracy supported?
A: 30 mm ball-type linear guideways, precision ball screws, a rigid bed and stable servo feed; X/Z rapid traverse is 24 m/min.
Q: What service and training are included?
A: The machine is offered with warranty, on-site installation and commissioning, and operation and maintenance training. Specific warranty terms are subject to the contract.
