机械加工产品的质量主要受零件的加工质量和产品的装配质量的影响最为关键,零件加工质量是保障机械加工产品质量的前提,制约零件加工质量的因素有加工精度和表面质量两方面内容。现分析了机械加工精度的基本内容、工艺系统中的加工原理误差和机床的几何误差。通过这些影响机械质量的问题进行分析,对提高机械加工质量提供参考依据。 The quality of machining products is mainly affected by the processing quality of the parts and the assembly quality of the products. The processing quality of the parts is the premise of guaranteeing the quality of the machining products. The factors that restrict the processing quality of the parts are the machining accuracy and the surface quality. Now analyze the basic content of machining accuracy, processing system in the process of error and machine geometry error. Through these problems that affect the quality of machinery for analysis, to improve the quality of machining provides a reference.
