Product Details

1. The material is 35CrMo, and the product is primarily hydraulic components for a shipyard, with dimensional accuracy to Grade 6 and surface roughness of Ra 0.4.
2. Challenges: These parts feature high dimensional accuracy for both the outer diameter and inner bore, narrow sealing grooves, and multiple narrow sealing grooves distributed within the inner bore as well.
3. Primarily employs CNC turning for rough and finish machining, followed by precision grinding of the outer diameter and inner bore to ensure dimensional accuracy and surface roughness.
