Frequently asked questions

Specifications and capacity
Q: What are its maximum dimensions?
A: Φ580 mm swing over bed, Φ420 mm maximum machining diameter, Φ370 mm over the toolholder and 510 mm maximum length.
Q: What bar size can it accept?
A: Maximum bar capacity is Φ52 mm; spindle bore is Φ65 mm, with an 8-inch hydraulic collet.
Q: What operations can it perform?
A: Its 12-position live turret supports turning, milling, drilling and tapping in one setup.
Q: What is the spindle output?
A: Up to 4,000 rpm, 11 kW and 72 N·m maximum torque, with A2-6 nose.

Machine selection
Q: How does a turning center differ from a conventional CNC lathe?
A: A turning center’s live turret can rotate tools for milling, drilling and tapping as well as turning, reducing additional setups where these operations are required.
Q: HMS-550M or HMS-750M?
A: Both list 510 mm machining length. The 550M has 600 mm Z travel and an 11 kW spindle; the 750M has 800 mm Z travel and a 15 kW/98 N·m spindle. Assess shaft length and cutting load when selecting.

Production and service
Q: Can it machine long shafts?
A: Yes. The standard Morse No. 5 tailstock has a Φ80 mm quill and 80 mm travel.
Q: Can it use a bar feeder and chip conveyor?
A: Yes. Both can be configured for continuous batch production.
Q: How is accuracy supported?
A: 45 mm ball-type linear guideways, precision ball screws, SYNTEC servo drive and reliable turret positioning reduce repeat setup errors.
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.
