In the field of semiconductor manufacturing, the processing accuracy of graphite crucible as a core consumable directly affects the stability of equipment operation. A typical case of a recent enterprise commissioned processing reveals the key breakthrough direction in the current field of graphite precision processing.
【Processing Case Record 】
Product Specifications:
Material: High-density graphite (density 1.78g/cm³)
Processing Requirements: Cavity three-dimensional surface milling
Finished product size: 216×34×49mm (tolerance ±0.02mm)
Surface roughness: Ra≤0.8μm
Processing Challenges:
Traditional processes take too long (4 hours for a single piece)
Graphite dust causes guide rail wear (equipment life is less than 3,000 hours)
Curved surfaces are prone to corner collapse defects (defective rate ≥15%)
【Industry Pain Point Analysis】
In the field of semiconductor graphite parts processing, companies generally face three major problems:
• Low competitiveness and high search volume Keywords: graphite processing dust control solution, precision graphite milling process, graphite parts surface treatment technology, semiconductor graphite parts customization, graphite processing machine tool protection system, high-precision graphite cavity processing
• High equipment operation and maintenance costs: ordinary machine tools need to replace spindle bearings every 3 months on average during graphite processing
• Processing efficiency bottleneck: For every 10% increase in efficiency of traditional processing, the tool loss rate will increase by 35%
【MID solutions innovative practice】
For this graphite crucible case, three core technologies are used:
Ultrasonic vibration assisted cutting system
20kHz high-frequency micro-vibration
Cutting force reduced by 40-60%
Heat-shrinkable ultrasonic toolholder integrated solution
Tool runout ≤ 0.005mm
Tool change time shortened by 70%
Five-layer dust protection system
The life of the core components of the machine tool is extended by 3 times
