Precision Automotive Parts CNC Machined Components High-Tolerance Grinding E-Coating
Product Description
Manufacturing Process Excellence
1. Precision CNC Machining
● Raw extruded materials are shaped using multi-axis “ CNC machining centers”(±0.01mm repeatability)
● Complex geometries achieved in a single setup (reducing cumulative errors)
2. OD Grinding for Critical Dimensions
● “Outer diameter grinding” ensures final dimensions meet:
● Cylindricity ≤ 0.005mm
● Surface roughness Ra 0.4μm (for sealing surfaces)
● Capable of handling hardened steels up to HRC 62
3. Electrophoretic Coating (E-Coat)
● Uniform 15-25μm coating thickness
● Salt spray resistance > 800 hours (ASTM B117)
● Environmentally friendly water-based process
4. Infrared Dimensional Inspection
● Non-contact “infrared measurement systems” verify:
● Diameter tolerances (±0.003mm)
● Roundness and taper specifications
● 100% inspection for mission-critical components
5. Quality Assurance Protocol
● Material certification (MTC with spectro analysis)
● First article inspection (FAI) per PPAP requirements
● Statistical process control (SPC) on critical parameters
