Relationship Between Blade Thickness and Grinding Wheel Thickness:

To properly regrind HSS circular saw blades, the grinding wheel thickness should be slightly thinner than the blade thickness to ensure correct tooth sharpening without damaging the sidewalls.

Recommended Matching Rule:

Grinding Wheel Thickness ≈ 60%–80% of Blade Thickness

This ensures:

• The grinding wheel enters the tooth gullets smoothly
  
  
• No grinding marks on the blade flanks
  
  
• Accurate tooth shape and proper cutting geometry
  
• 
  

Example Calculation:

If your saw blade thickness is 3.5 mm, then:

Recommended wheel thickness: 2.2 mm – 2.6 mm

This ensures efficient tooth profiling without risk of overheating or flank damage.

Notes:

• A wheel thicker than the blade can cause side burn marks and tooth deformation
  
  
• A wheel too thin may vibrate or cause uneven sharpening
  
  
• CBN or resin-bonded wheels are recommended for durability and precision
  
  
• Avoid high-speed dry grinding; always use coolant to prevent annealing or softening

Additional Tips:

• Grinding wheel speed: 30–35 m/s is optimal
  
  
• Grinding depth per pass: 0.02–0.05 mm
  
  
• Tooth inspection interval: Every 200–300 meters of cutting
  
  
• In case of major chipping, consider full regrinding of the tooth profile
  
  
• Ensure consistent tooth depth and max height difference ≤ 0.02mm
