CKY4240–CKY4263 Crankshaft Main Journal Lathe

The CKY4240–CKY4263 is catalogued with distance between centres options of 500, 1000, 750, 1000, 1500, 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 CKY4240–CKY4263 carries a Metric 80 / Metric 100 / Metric 100 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.

The catalogued range is Stepless / Hydraulic 2 gears + stepless. The span matters more than the top figure: large diameters and tough materials live at the low end where torque does the work, while small-diameter finishing wants the top end. A range that covers both ends is what lets one machine carry mixed work.

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.

Standard configurations generally ship within 30 to 60 days of a confirmed order, with the date written into the contract. The CKY4240–CKY4263 then carries a 12-month warranty on main components, handled by the plant that built it, with lifetime technical support and spare parts identified by part number at handover.
