    All aspects of machine tool casting quality

    Release date:2017-12-12 Publisher:Yongxing

    The quality of machine tool castings mainly includes appearance quality, intrinsic quality and quality of use. Machine tool casting appearance quality refers to the machine tool casting surface roughness, surface defects, size deviation, shape deviation, weight deviation; the inherent quality of machine tool castings mainly refers to the chemical composition of the machine castings, physical properties, mechanical properties, microstructure and exist Machine tool casting holes, cracks, inclusions, segregation and so on.

    The quality of use of machine tool castings refers to the durable work ability of machine tool castings under different conditions, including wear resistance, corrosion resistance, heat shock resistance, fatigue, shock absorption and other properties as well as machinability, weldability and other process performance. Machine tool casting quality has a great influence on the performance of mechanical products. For example, the wear resistance and dimensional stability of machine tool castings, a direct impact on the accuracy of the machine to maintain life.
