CKY6146YG–CKY6171YG Hydraulic Cylinder Lathe

The catalogued range is 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.

Two build points matter most on this machine: one-piece bed in high-strength iron for rigidity and precision; and slant bed with linear guideways for process speed and accuracy. Structure decides how a machine ages — the specification table tells you what it does new, the build tells you what it does in year five.

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.

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 CKY6146YG–CKY6171YG 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.
