CNC Turning Machining Precision Punch

CNC turning machining parts for Pressure Bushings, also known as Precision Guide Sleeves.
This component provides guiding support for high-precision moving parts such as custom metal punch and mold ejector pins.

Customer Pain Points:
The wear/deformation of guiding components and movement jamming, directly affecting production yield and efficiency.

Our Analysis:
(1) Insufficient dimensional accuracy of the inner hole step size.
(2) Inadequate precision of the radius transition.
(3) Insufficient surface finish of the inner hole (not reaching Ra0.4).

Our Solutions:
(1) Precision Machining: CNC turning to ensure the outer dimensional accuracy, while inner hole grinding and punch grinder precision processing to guarantee tolerannce.
(2) Surface Treatment: Inner hole polishing to achieve a finish of Ra≤0.4, and TiALN coating to reduce friction coefficient by 60%.

Customer Verification Results:
The smoothness of guiding components improved by 90%.
Customer production efficiency increased by 22%.
