CK6185B Flat-bed CNC Lathe

The CK6185B carries a Φ130 mm main 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.

The catalogued range is 40-75; 75-150; 150-290; 290-620 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.

Two build points matter most on this machine: one-piece resin-sand cast bed, aged before machining; and way faces hardened by ultrasonic-frequency quenching. 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.

Both sit in the horizontal CNC 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 CK6185B 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.
