Heavy horizontal CNC lathe
CK61200G Heavy CNC Lathe
A heavy CNC horizontal lathe developed with 3D modelling, simulation and finite element analysis, and configured in modules so the mechanical, electrical and hydraulic systems work as one package. It turns outside and inside diameters, faces, cones, arcs and threads, and does grooving and parting. The bed carries two or three integral ways, medium-frequency hardened, with a steel-inlaid option; the headstock runs a through-shaft on two short bearings; the frame-type tool post has two vertical tool plates that retract freely; the feed box uses twin-gear backlash elimination for load capacity and drive rigidity. The tailstock is split upper and lower with automatic movement and sleeve clamping. Twin tool posts, milling-boring, grinding and coolant units are available, and the range and number of steady rests is configured to the work.

Model FAQs
Questions Engineers Ask About The CK61200G
What spindle speeds does the CK61200G run, and why does the range matter?
The catalogued range is 1–180 / 1–160 / 1–160 / 1–160 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.
What is built into the CK61200G that keeps it accurate?
Two build points matter most on this machine: two- or three-way integral bed, medium-frequency hardened, steel-inlaid optional; and through-shaft headstock on twin short bearings. 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 1250, 1600, 2000, 2500 mm swing on the CK61200G 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.
What separates the CK61200G from the CK61315F in this group?
Both sit in the heavy 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.
What acceptance testing does the CK61200G go through?
Every CK61200G 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.
