Gang-tool CNC lathe
SKD-20-30F Gang-tool CNC Lathe
High Precision Spindle The machine spindle bearing adopts Japanese NSK/NTN ultra high precision angular contact ball bearings, ensuring high rigidity and long lasting accuracy retention of the spindle, with spindle runs out <2µm. -20/30F Efficient Processing The max speed of the machine spindle is 6000 revolutions per/min, and the fast moving speed of X and Z axis can reach 20m meters per/min. automatic feeding machines can be configured to achieve high speed and efficiency automated processing. High Precision Feeding Full servo drive for each feed axis, using Japanese NSK/THK high precision ball screw to ensure machining accuracy and long term accuracy maintenance, and repeated positioning accuracy for each feed axis< ±1µm. Bed Structure Adopt high quality densely baked integral cast iron bed Gang Tool Holder The new blade arrangement tool holder min the error of repeated tool changes,

Model FAQs
Questions Engineers Ask About The SKD-20-30F
What should I look at inside the SKD-20-30F 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-20-30F or SKD-40L — 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.
What acceptance testing does the SKD-20-30F go through?
Every SKD-20-30F 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.
How soon can the SKD-20-30F 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-20-30F 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.
