Improving Surface Precision in Precision Machined Parts

The precision achievable through precision machining serves as a key indicator of a nation's manufacturing capabilities. As machining accuracy continues to advance, the demands on the machine tool's surrounding environment grow increasingly stringent. Beyond fluctuations in hydraulic and pneumatic systems during precision machining, factors such as ambient temperature, cleanliness, and vibration significantly impact processing quality. To enhance the surface precision of precision mechanical components, multiple-pass cutting technology has emerged.

Multiple-pass cutting technology serves as the fundamental approach for enhancing the precision and surface quality of precision mechanical parts through wire electrical discharge machining (EDM). Typically, the initial pass achieves basic shaping, the second pass refines dimensional accuracy, and subsequent passes improve surface finish quality.
