Customer Overview and Project Need


Precision CNC Machining Solution

The customer, a leading semiconductor manufacturer based in Europe, specializes in producing high-precision components for the semiconductor industry. Their production line faced increasing demand for multi-cavity vacuum shells, which are critical components in semiconductor fabrication equipment. The challenge was twofold: the components had to meet stringent dimensional tolerances while being produced in high volumes. Additionally, the customer needed to optimize their production costs without sacrificing quality.

As the semiconductor industry evolves, it faces several technical challenges, including the need for higher precision and faster production cycles, alongside materials that can withstand extreme operating conditions. The client's project required a solution that could not only meet these high standards but also be scalable for mass production.


Project Description and Technical Challenges


The customer's primary challenges included:

  • Precision Requirements: The multi-cavity vacuum shells needed to be manufactured with an extremely tight tolerance, requiring precision machining techniques.

  • Material Complexity: The parts were to be made from high-performance materials, which required specialized tools and machining strategies.

  • Complex Geometry: The multi-cavity design introduced complexities in machining due to the need for precise alignment and internal features.

  • Volume and Time Constraints: The project also demanded rapid production to meet growing market demands, without compromising quality or increasing costs.

The project's objective was to manufacture these vacuum shells with high precision and within an expedited timeline, while ensuring that the parts could be scaled up for large-scale production.


Solution and Implementation Process


To meet the customer's high standards, Xiamen Prime KunWu Technology Co., Ltd. implemented the following solutions:

  • Advanced CNC Machining: The project was tackled using state-of-the-art CNC machining technology, which ensured the parts were manufactured with high accuracy. We utilized 5-axis CNC machines, which provided flexibility and precision, especially for complex geometries.

  • Wire-cut EDM (Electrical Discharge Machining): To achieve the intricate internal cavities and sharp edges, Wire-cut EDM was employed. This method ensured high precision in delicate areas, which were critical to the overall design integrity.

  • Material Selection: The customer’s vacuum shells required a material that could withstand both high temperatures and mechanical stress. We selected titanium alloy due to its excellent thermal stability and strength-to-weight ratio. This material choice ensured that the final product could perform reliably in the harsh conditions of semiconductor fabrication environments.

  • Quality Control and Testing: Stringent quality control procedures were applied at every stage of production. After machining, each component underwent CMM (Coordinate Measuring Machine) inspection to verify dimensional accuracy, ensuring that every part met the customer’s tight tolerances.

  • Optimization for Mass Production: Given the customer’s need for high-volume production, we optimized the manufacturing process by fine-tuning machining parameters to maximize efficiency without sacrificing quality. This included adjusting feed rates, tool paths, and using advanced cutting fluids to extend tool life.


Results and Achievements


The project successfully met the customer’s demanding requirements. Key outcomes include:

  • Production Time Reduction: The implementation of CNC machining and Wire-cut EDM helped reduce the overall production time by 30%, allowing the customer to meet tight delivery deadlines.

  • Enhanced Precision: The use of high-precision machining methods resulted in components being produced within 0.01mm tolerance, surpassing the initial specifications.

  • Cost Optimization: By optimizing the production process and materials, we were able to reduce manufacturing costs by 15% without compromising quality.
