Introduction
STAR CNC Swiss-type lathes are imported high-precision shaft machining equipment widely used in mass production of precision electronics, medical devices, and miniature automotive components. Compared to standard domestic Swiss-type lathes, they are more sensitive to maintenance details and operating conditions. Maintenance must follow manufacturer standards across four dimensions: daily inspections, core components, auxiliary systems, and electrical precision calibration.
1. Daily Cleaning and Startup Inspection
- Before shift: Check air pressure, cutting fluid level, lubricating oil level. Confirm no residual alarms.
- After shift: Clean spindle guide bushing, bar feeder, tool holder chips. Inspect guards and pipelines.
2. Core Precision Component Maintenance
Guide bushing, collet, and spindle system are the precision core and fastest-wearing parts.
- Clean spindle taper bore and sub-spindle collet surfaces regularly.
- Replenish main and sub-spindle gripper lubrication on schedule.
- Test guide bushing concentricity periodically; replace when wear exceeds specs.
3. Auxiliary Systems Maintenance
- Lubrication: Use STAR-spec guideway oil and spindle oil. Replace hydraulic oil and filters regularly.
- Cutting fluid: Test concentration, clean tank, prevent odor and corrosion.
- Pneumatics: Clean filters and silencers. Maintain stable air pressure.
4. Electrical System and Parameter Protection
- Monthly: Clean cabinet dust, tighten terminals and encoder connectors.
- Annually: Replace absolute encoder battery to prevent zero-point data loss.
- Back up system parameters and programs regularly.
5. Monthly Precision Calibration
- Recalibrate machine origin, axis backlash, spindle runout, tool position accuracy.
- Correct deviations from long-term operation promptly.
- Standardized maintenance maximizes precision, reduces downtime, extends service life.
