c: 100% inspection
Use of equipment and tools: CNC machine / Flat-bottomed cutter / Drill bit / Tap processing fixture / File / Wind grinder / 120# sandpaper
Precautions
a. Do not over cut, no sand holes, no sharp corners, miss processing; without scratch, no burr; and the R corners should be connected smoothly.
b. Ensure the finish of the processed surface is Ra 0.8, control the size and shape tolerances.
c. Inspection by go gauge and no-go gauge.
d. Check the flatness of the product according to the drawing.
e. Handle the product gently to prevent deformation.
Step 06
Polishing, (manual removal)
Remove product clamping line caps, surface particles, slag bags, and gate residues.
Precautions
a. No processing be missed, no sharp corners, no sharp edges and the mold closing line should be connected smoothly.
b. Ensure the finish of the processed surface is Ra 0.8, control the size and shape tolerances.
c. Inspection by go gauge and no-go gauge.
d. Check the flatness of the product according to the drawing.
e. Handle the product gently to prevent deformation.
Step 07

Tools: Dispensing machine, dispensing fixture
Precautions
1. Glue strips must be uniform, no breakage, accumulation, drawing, glue overflow, deviation, bubbles, falling off, etc.
