Mastering Polishing Machine Operation: A Scientific Approach to Perfect Surface Finishing

Understanding the Core Polishing Mechanism

Polishing machines operate on a fundamental principle of controlled abrasion, where material removal must balance speed and precision. The process involves two critical phases:

1. Coarse Polishing

   • Purpose: Rapidly eliminate grinding marks

   • Parameters:
     • Wheel speed: ≤600 RPM
     • Abrasive: Diamond/CBN compounds (#80-#120)
     • Pressure: 3-5 kg/cm²

2. Fine Polishing

   • Purpose: Eliminate subsurface damage

   • Parameters:
     • Wheel speed: 800-1200 RPM
     • Abrasive: Colloidal silica (0.05μm)
     • Pressure: 1-2 kg/cm²

5 Professional Techniques for Optimal Results

✅ Parallelism Control

• Use laser alignment tools to ensure specimen-platen parallelism (≤0.01mm deviation)

✅ Suspension Management

• Maintain ideal slurry viscosity (30-50 cP measured by viscometer)

• Automatic dispensing systems recommended (flow rate 5-10ml/min)

✅ Temperature Regulation

• Infrared monitoring keeps surface temp <50°C (prevents alloy distortion)

✅ Pattern Optimization

• Programmable X-Y oscillation (5-10mm amplitude, 10-15 cycles/min)

✅ Wheel Maintenance

• Diamond dressing tools renew surface texture (Ra 2-3μm optimal)
