I. Scale of Time: Natural Ageing

Every JSWAY Swiss-type lathe first undergoes several weeks of constant-temperature resting. No heating, no cutting—only time and temperature slowly release casting stresses, eliminating “invisible deformation” of the bed and guideways. This is JSWAY’s first time insurance for micron-level accuracy.

II. Scale of Space: Side-Master-Line Calibration

After resting, a laser interferometer scans the bed side-master-line—the “invisible spine” that determines transverse tool-post accuracy. We adjust guideway clamping forces point by point to lock side-master-line error within tolerance, then recheck with a wireless rotary-axis calibrator—any drift triggers an alarm. A stable side-master-line means no chatter on long shafts.

III. Scale of Motion: Running-in + Three Checks & Two Tests
• Running-in: high-speed idle cycles + simulated cutting loads bring bearings, guideways and ball screws to optimal磨合.
• Three Checks: self-check, mutual check, specialist check—every cut and every bore is signed off.

• Two Tests: on-line laser detection + finished running-in test—only when all data are “green” is the machine allowed into the container.

IV. Scale of Data: Zero-Defect Report

Each Swiss-type lathe is accompanied by a “zero-defect report” — natural-ageing curve, side-master-line scan, running-in temperature graph, laser test data — all scannable for traceability. Customers receive not a sheet of paper but a traceable “accuracy journey”.

V. Scale of Commitment: Lifetime Companionship
• Factory-equipped “Equipment Health ID” — scan to view production, inspection and running-in data.
• On-site side-master-line re-calibration service to restore factory accuracy.
• Common clamping blocks and tailstock pins shipped within hours, eliminating downtime waiting.

One-Sentence Summary
Write “micron” into the scale of time — let natural ageing, side-master-line, running-in and laser detection become the “birth certificate” of every Swiss-type lathe. This is the lifetime accuracy insurance JSWAY provides for your precision manufacturing.
