Equipment: knife-edge ruler, shaping fixture
Within 0.25mm of the front plane of the product
CNC (CNC machining + Deburring + Full material inspection)
A. CNC machining: Process the end face of the inner cavity, the end face of the surrounding heat dissipation tooth surface, and the through holes of the tooth holes.
Equipment: CNC machine, flat-bottomed cutter, drill bit, tap processing fixture.
B. Deburring: The sharp corners of the product are chamfered, deburred, non-machined ejector pins are sharpened, and polished to smooth the appearance.

C. 100% material inspection: Appearance visual inspection.
a. Do not over-cut or miss processing;
b. Be careful not to scratch or burr the surface;
c. Ensure the finish of the processed surface is Ra0.8, and the size and shape tolerances. No processing should be missed, no sharp corners or burrs should be removed, and the R corners should be connected smoothly.
d. The surface of the product must be free of overcutting, sand holes, lack of material, burrs, and other undesirable phenomena.
e. Via pass and stop gauge detection.
f. Check the flatness of the product according to the drawings.
g. Handle the product gently to prevent deformation.
IPQC Inspection
Visual inspection of appearance
Polish (Manual Removal)
Remove product clamping line caps, surface particles, slag bags, and gate residues.
