CNC Parts - Automatic Positioning Fixture

The automatic positioning fixture for mobile phone assembly is mainly used to ensure the accurate positioning of mobile phone components during the assembly process, as well as to provide stability and safety during operation.

Pain Points:
– Insufficient Machining Accuracy: Low accuracy (±0.1mm), leading to component misalignment, with a yield rate of only 87%.
– Rapid Material Wear: Frequent friction, resulting in a fixture life of less than 5 months.

Solutions:
* Precision Machining: Use precision CNC machining solutions (surface grinding → CNC milling → precision grinding → EDM wire cutting) to ensure that the dimensions and shape accuracy of the fixture reach ±0.01.
* Material Upgrade: Choose SKD11 tool steel to enhance wear resistance by 100%.
* Heat Treatment Optimization: Achieve stable hardness of HRC58-60 through vacuum hardening and triple tempering.
* Surface Optimization: Apply chrome plating (thickness of 10μm) to reduce the friction coefficient by 40%.

Effectiveness Verification:
1. Yield Improvement: Assembly qualification rate reaches 99.5%.
2. Lifespan Extension: Lifespan extends to 13 months.
3. Increased Production Efficiency: Production efficiency of the automated production line increases by 59%.
