CNC pipe threading lathe
QKY (slant bed) CNC Pipe Threading Lathe
Built for oilfield tubulars: cutting and recutting internal and external pipe threads on drill pipe, tool joints and casing. It also works as a general CNC lathe on shaft and disc parts between threading jobs.

Model FAQs
Questions Engineers Ask About The QKY (slant bed)
Is the QKY (slant bed)’s 630 / 630 / 660 / 630 mm swing the real working diameter?
Swing over bed is clearance — twice the distance from spindle centreline to the bed ways — not the working limit. The working figure on the QKY (slant bed) is the 560 mm maximum turning diameter, measured with the tooling in place. Quote your largest finished diameter plus workholding, and check it against that second number, not the headline swing.
How large a bar passes through the QKY (slant bed)’s spindle?
The QKY (slant bed) carries a 120 / 150 / 206 / 225 mm spindle bore. 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.
What spindle speeds does the QKY (slant bed) run, and why does the range matter?
The catalogued range is 1000 / 800 / 550 / 550 r/min. 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.
QKY (slant bed) or QK13 (550 guideway) — which fits my work?
Both sit in the cNC pipe threading 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.
What acceptance testing does the QKY (slant bed) go through?
Every QKY (slant bed) 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.
