Model FAQs
Questions Engineers Ask About The QK13 (755 guideway)
What spindle speeds does the QK13 (755 guideway) run, and why does the range matter?
The catalogued range is VF, 4 steps / VF, 3 steps / VF, 3 steps. 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.
What is built into the QK13 (755 guideway) that keeps it accurate?
Two build points matter most on this machine: large spindle bore with high pass-through, twin chucks holding the work steady; and one-piece bed in high-strength cast iron for rigidity 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.
What does the 1000 mm swing on the QK13 (755 guideway) actually let me turn?
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.
QK13 (755 guideway) or QKD13 (755 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.
How is a new QK13 (755 guideway) proven before it ships?
Every QK13 (755 guideway) 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.
