The processing of copper round bars requires precise machining technology, particularly focusing on the use of 5-axis machining centers and NC lathes. In screw machining, there are two types: rolling and cutting, each with its own advantages, but some methods may take longer. Additionally, strict quality control is implemented, and only products that pass inspections using ring gauges are shipped. This ensures the high quality of copper products.
