graphite

1. Efficient forming of EDM electrodes

 

Scenario pain points:

Graphite electrode processing dust accumulates seriously, traditional tools wear quickly (life < 4 hours), and edges and corners are prone to chipping (tolerance >± 0.05mm).

 

Solution:

Tool technology: diamond-coated end mill (grain size 5μm) + spiral chip removal groove design, integrated high-pressure air cooling system (pressure 0.8MPa).

Technical parameters: Tool life extended to 20 hours, edge chipping < 0.01mm, surface roughness Ra0.8μm.

Application case: EDM electrode processing of automotive covering parts, the number of electrodes per day has been increased to 200 pieces, and the dust collection efficiency has reached 95%.

 

2. Microstructure processing of glass molds

 

Scenario pain points:

The surface micro-texture (depth of 0.05-0.1mm) on the surface of the glass bottle mold is prone to burrs and needs to be trimmed many times.

 

Solution:

Tool technology: multi-edged nano-grain diamond engraving knife (edge width 0.1mm) + five-axis linkage dynamic focus control.

Technical parameters: Texture depth consistency ±0.005mm, single processing and molding, efficiency increased by 70%.

Application case: High-end wine bottle mold processing, texture clarity up to ISO 1302:2002 standard, yield rate 99.5%.

 

 

3. Anti-chipping processing of thin-walled graphite parts

 

Scenario pain points:

The edge chipping rate of the thin-walled structure (thickness 0.5mm) of the injection mold of the mobile phone frame is > 10% during processing.

 

Solution:

Tool technology: Negative rake carbide milling cutter (30° helix angle) + layered cutting strategy (0.02mm depth per layer).

Technical parameters: The edge chipping rate is reduced to 0.5%, the wall thickness tolerance is ± 0.003mm, and the processing speed is 150m/min.

Application case: 3C product graphite mold processing to achieve mass production of 0.3mm ultra-thin wall structure.

 

 

4. Deep cavity mold dust control

 

Scenario pain points:

The deep cavity structure (diameter ratio >10:1) makes it difficult to discharge machining dust, resulting in abnormal tool wear.

 

Solution:

Tool technology: internally cooled deep cavity milling cutter (dual-channel chip evacuation) + electrostatic adsorption dust removal system.

Technical parameters: Dust residue < 5mg/m³, tool life increased by 3 times, and processing efficiency increased by 50%.

Application case: Aerospace composite molding mold processing, cavity depth 80mm processing without dust accumulation.
