Case Background
A manufacturer specializing in high-performance automotive components faced a challenge: they needed to produce a series of high-precision aluminum alloy pistons for a new sports car. These pistons must not only withstand extreme thermal stress and mechanical loads, but also have excellent surface finish to ensure optimal engine performance.
Customer Requirements
The pistons required by the customer must meet the following standards:
Extremely high dimensional accuracy and shape consistency.
Surface roughness Ra value less than 0.2 microns to reduce friction and improve wear resistance.
The processing must be environmentally friendly and meet the latest industrial emission standards.
Solution
We proposed a solution that combines CNC turning and advanced polishing technology. CNC turning is used to quickly remove material and form the basic shape of the piston, while polishing is used to improve the surface finish.
Processing process
Material selection: A high-strength aluminum alloy was selected for its light weight and good thermal conductivity.
CNC turning: In a constant temperature and humidity environment, our CNC turning machine accurately processes the pistons, ensuring dimensional accuracy and shape consistency.
Polishing: The machined pistons were professionally polished using an environmentally friendly polishing compound to achieve a mirror-like surface finish.
Quality Inspection: The parts were rigorously quality inspected using a coordinate measuring machine (CMM) to ensure that each part met the design specifications.
Customer Feedback
The customer was very satisfied with our service. They particularly appreciated the customized solutions we provided in a short time, as well as the excellent quality and unique appearance of the products. The precision and surface quality of the pistons exceeded their expectations, and our delivery time was even faster than expected.
Project Results
By using CNC turning technology and precision polishing processes, we not only improved the quality and performance of the parts, but also helped the customer maintain a leading position in the fierce market competition.
Conclusion
This case demonstrates the application of CNC turning technology combined with polishing technology in the manufacture of automotive parts, and how it helps customers achieve high standards of production requirements. Through precise processing and strict quality control, CNC turning technology provides a reliable solution for the manufacture of automotive parts
