Scientific Maintenance Guide for Mirror Polishing Machines (With Operational Optimization Tips)

I. Core Maintenance Essentials

1. Precision Speed Control

• Optimal RPM Ranges:

  Material	Rough Polishing (RPM)	Fine Polishing (RPM)
  Stainless Steel	1200–1800	800–1200
  Aluminum Alloy	1000–1500	600–1000
  Optical Glass	500–800	300–500

• Operational Tips:

  • Use gradual acceleration via frequency converter (≥15 sec from 0 to full speed).

  • For mirror finishes, adopt "Low-Speed High-Precision" mode.

2. Angle Standardization

• Ideal Contact Angle: 3°±2° (perpendicular to workpiece).

• Consequences of Deviation:

  • >5°: Wheel uneven wear (↓40% lifespan).

  • Angle errors: Increased surface waviness (↑30% Ra value).

II. Three-Level Maintenance System

III. Critical Component Lifecycle Management

1. Consumable Replacement Standards:

• Polishing wheel: Replace if thickness < 1/3 original or radial cracks appear.

• Carbon brushes: Replace if length < 1/2 original (check every 200h).

• Drive belts: Replace immediately if >3 transverse cracks.

2. Precision Maintenance:

• Monthly: Measure spindle runout with dial indicator (≤0.01 mm).

• Quarterly: Calibrate worktable level (≤0.02 mm/m).

IV. Fault Early Warning & Troubleshooting

V. Smart Maintenance Upgrades

1. IoT Monitoring:

• Install vibration sensors (real-time bearing health tracking).

• Receive APP alerts (e.g., "Carbon brush life remaining: 10%").

Key Notes:

• Store polishing wheels in dark, dry conditions (<60% RH).

• Release hydraulic pressure if idle >72 hours.

• Factory recalibration recommended every 2000h (laser alignment).

Results: Proper maintenance extends machine life by 3–5 years and reduces costs by 40%. Maintain an Equipment Health Log for all service records.
