Introduction
Semiconductor manufacturing is one of the most demanding industries in modern precision engineering.
Unlike general industrial parts, semiconductor equipment components require ultra-high precision, excellent flatness, superior surface finish, tight geometric tolerances, excellent thermal stability and long-term dimensional consistency.
Even a tiny dimensional deviation may affect vacuum performance, equipment stability, wafer yield and production efficiency.
As the semiconductor industry continues to grow rapidly, the demand for precision CNC machining is increasing worldwide.
Today, CNC machining is widely used for vacuum chambers, precision aluminum plates, structural frames, electrostatic chucks, semiconductor fixtures, cooling plates and process equipment components.
