Various typical precision parts processing techniques in Dalian, including shaft parts, sleeve parts, piston parts, disc parts, cylindrical gear parts, bevel gear parts, end gear disc parts, worm gear parts, and box parts, totaling 9 chapters. For each type of component, the structural characteristics and technical requirements of the component, processing technology analysis and selection of positioning benchmarks, materials and heat treatment, testing, and other contents were first introduced; Then, taking the machining process as the main line, some typical machining examples were introduced from three aspects: part drawing analysis, process analysis, and machining process. This book can provide readers with a comprehensive understanding of the mechanical processing techniques for various typical precision parts, which can be applied in production practice with strong practicality and pertinence.
