CKY6140-6150 Slant-bed Lathe

Swing over bed is clearance — twice the distance from spindle centreline to the bed ways — not the working limit. Quote your largest finished diameter plus workholding, and check it against that second number, not the headline swing.

The CKY6140-6150 is catalogued with distance between centres options of 500, 1000, 1500 and 2000 mm. Work from your longest finished part plus chucking and parting allowance, and remember slender work on the longer beds wants steady rests quoted with the machine. Buying excess bed costs floor space and money every day after delivery.

The CKY6140-6150 carries a Metric 80 spindle bore taper. Remember usable bar capacity always runs smaller than the bore itself once the chuck or collet mechanism is in place, so check your maximum bar stock against the workholding you intend to run, not against the bore figure alone.

Both sit in the slant-bed lathe group, so the decision is capacity and duty, not kind: put your largest part dimensions, material and yearly quantity against each specification table and one of the two will run out of a figure first. Send the drawing and we will name which of the two fits — including the case where the smaller machine does the job.

Every CKY6140-6150 is laser-measured to ISO 230-2 over its travels, cuts a test piece that is measured rather than admired, and ships with a serial-numbered report carrying the measured values. If any line misses, the machine goes back into the shop until it passes — the report is a record, not a promise.
