Gang-tool CNC lathe
SKD-40L Gang-tool CNC Lathe
A small precision lathe with a gang tool holder rather than a turret, for short shaft and disc parts in instrument, electronic, medical and automotive component work. Repeat tool-change error is minimal because the tools do not index.

Model FAQs
Questions Engineers Ask About The SKD-40L
Why does the SKD-40L hold its geometry under real work?
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.
What separates the SKD-40L from the SKD-J20-30 in this group?
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 soon can the SKD-40L ship, and what covers it afterwards?
Standard configurations generally ship within 30 to 60 days of a confirmed order, with the date written into the contract. The SKD-40L 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.
How is a new SKD-40L proven before it ships?
Every SKD-40L 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.
