How does RuiXing MFG deal with CNC machined heat sink with high requirements

×

Challenges:

The part in question presented several challenges that impacted both time and resource efficiency in the CNC machining process:

 

 

1. Material Removal and Prolonged Machining Time:

   - The requirement to remove a significant amount of raw material extended machining times considerably.

2. Fine Machining of Heat Sink Fins:

   - The narrow gap of 3mm between heat sink fins, each 30mm in height, mandated the use of slender and elongated cutting tools. However, this compromised tool rigidity, slowing down machining speeds.

 

3. Single-Pass Machining for 1mm Thick Fins:

   - Achieving the specified tolerance in the first machining operation is essential because there is no opportunity for rework. The thinness of the heat sink poses a high risk of fracture upon contact with the cutting tool, making it imperative to ensure accuracy and stability during the initial machining.

Results:

The optimization strategies implemented yielded notable outcomes:

 

- Reduced Machining Time:

The introduction of 3+2 axis milling for side holes led to a remarkable 10% reduction in machining time, streamlining the overall production process.

 

- Enhanced Precision:

The optimized approach not only lowered costs but also improved the precision and accuracy of the machined components, mitigating errors introduced during the clamping process.

 

- Improved Tool Utilization:

By addressing the challenges associated with fine machining of the heat sink fins, the optimization ensured better tool utilization, minimizing wear and enhancing efficiency.
