- Axial alignment: ±0.01mm
- Measurement tools:
- Dial indicators (0.001mm resolution)
- Laser alignment systems
- Precision straight edges
- Conduct laser alignment of saw wheels:
Tension Optimization Protocol
-
- Proper tensioning procedure:
- Measure blade thickness with micrometer
- Calculate required tension (N/mm²) based on blade width
- Use strain gauge tension meter for verification
- Recommended tension values:
- Carbon steel blades: 250-300 N/mm²
- Bimetal blades: 300-350 N/mm²
- Carbide-tipped blades: 350-400 N/mm²
- Proper tensioning procedure:
