Gang-tool CNC lathe
SKD-J20-30 Gang-tool CNC Lathe
SKD-J30 CNC lathe is a high precision and high performance small precision CNC lathe independently developed by our company. The machine tool has good dynamic performance, accurate control of motion accuracy, stable and consistent processing accuracy, and can be continuously controlled in two coordinates. It is used for processing various short axis and disc parts, and can automatically complete the processing of rotation surfaces such as inner and outer circular surfaces, conical surfaces, arc surfaces, end faces, and thread turning. Suitable for mass and efficient process of various high precision, complex small rotating parts in industries such as instruments and meters, electronic communication, medical equipment, aerospace, automotive parts, etc. SKD-4OL High Precision Spindle the machine adopts imported sleeve type spindle and Japanese ultra high precision spindle bearings, ensurin

Model FAQs
Questions Engineers Ask About The SKD-J20-30
What should I look at inside the SKD-J20-30 beyond the spec table?
Two build points matter most on this machine: nsk/ntn ultra-precision angular contact spindle bearings, run-out under 2 µm; and gang tool holder removes turret indexing error and saves cycle time. 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.
SKD-J20-30 or C61200A — which fits my work?
Both sit in the gang-tool 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.
How is a new SKD-J20-30 proven before it ships?
Every SKD-J20-30 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.
What is the lead time and warranty on the SKD-J20-30?
Standard configurations generally ship within 30 to 60 days of a confirmed order, with the date written into the contract. The SKD-J20-30 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.
