Slant-bed CNC lathe
SKD-550 Slant-bed CNC Lathe
The unique design concept of SKD-550 comes from the world famous brand machine tool 1. Adopting an advanced 30°combined inclined bed structure, the machine achieves the min floor area while maintaining excellent rigidity and precision performance. 2. The spindle of the machine is designed with the concept of high speed, heavy duty, and high precision, which can easily achieve strong heavy cutting. 3. The machine adopts a 12 station hydraulic/servo turret to ensure the speed exchange accuracy, and rigidity of the tool change. X/Z axis is driven by Japanese THK precision ball screws, combined with Japanese THK linear rolling guide way, and has good dynamic characteristics. The machine is equipped with a hydraulic tailstock.

Model FAQs
Questions Engineers Ask About The SKD-550
What spindle speeds does the SKD-550 run, and why does the range matter?
The catalogued range is 35–4000 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 SKD-550 that keeps it accurate?
Two build points matter most on this machine: one-piece 30° or 45° slant bed for rigidity and accuracy retention; and spindle designed for high speed, heavy duty and high precision. 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.
How do I choose between the SKD-550 and the SKD-560?
Both sit in the slant-bed 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-550 proven before it ships?
Every SKD-550 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.
