⚠️ Common Sheet Metal Processing Pain Points

Burrs on Stainless Steel Chamfers

Standard tools lack hardness, stainless steel cutting produces burrs requiring secondary deburring

Short Tool Life

Frequent tool changes in mass production reduce efficiency and increase tooling costs

Uneven Countersunk Holes

Inaccurate tool angles prevent screw heads from seating fully, affecting assembly quality

✅ Lihao Technology Solutions

Cobalt HSS Material

HRC67 hardness with toughness - no chipping on stainless steel, smooth burr-free surface

TiAlN Composite Coating

0.15 friction coefficient, no chip welding, smooth chip evacuation, 40% higher efficiency

Precision Grinding

Angle tolerance +/-0.1 degrees, flat countersunk holes, screw heads fully seated
