Frequently asked questions

Specifications and capacity
Q: What are the maximum machining dimensions?
A: Swing is Φ500 mm over the bed and Φ290 mm over the cross slide, with 1,000 mm between centers.
Q: What is the spindle bore?
A: The A2-8 spindle has a Φ82 mm bore and can be fitted with a chuck or collet.
Q: What is the speed range?
A: 65–1,600 r/min in three geared ranges, with stepless servo adjustment within each range.
Q: Can it support long shafts?
A: Its Φ75 mm tailstock quill has 150 mm travel and an M5 taper; distance between centers is 1,000 mm.

Machine selection
Q: How do flat-bed and slant-bed lathes differ?
A: Flat-bed guideways are horizontal, with a simple, rigid and economical structure suited to general and heavier machining. Slant-bed machines offer convenient chip removal and suit high-speed precision work.
Q: How does the CK-6150B compare with the CK-6140?
A: The 6150B has Φ500 mm swing, 1,000 mm between centers and a Φ82 mm bore. The more compact 6140 has Φ420 mm swing, 750 mm between centers and a Φ66 mm bore. Consider the 6150B for parts exceeding the 6140’s dimensions.

Production
Q: Can it machine bar stock?
A: Yes. The Φ82 mm spindle bore accepts bar stock with a suitable chuck or collet; the tailstock supports long shafts.
Q: What parts suit it?
A: Medium and large shafts and discs, automotive and general machinery parts, and mold spares.

Accuracy and support
Q: How is machining stability maintained?
A: The cast-iron bed, straight guideways and geared spindle provide rigidity and low-speed torque.
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.
