CNC Milling Machining Shear Blades

These machined precision parts are mainly used to cut materials, ensuring precise dimensions and shapes.

Product Pain Points:
The blade edges are prone to dulling or chipping due to wear, which reduces cutting accuracy and requires frequent replacements, increasing downtime and production costs.

Improvement Solutions:
1. Material Selection: Use high-carbon high-chromium cold working die steel Cr12/1.2080 (DIN standard) with high wear resistance.
2. Heat Treatment: Use vacuum quenching and three tempering to balance hardness (HRC62) and toughness.
3. Precision Machining: Use cnc wire edm to ensure profile accuracy and surface finish (Ra ≤ 0.8 μm) of the blade edge.

Effects:
The blade life is extended by 67%, cutting efficiency is improved by 20%, and production cost is reduced by 15%.
