随着工业的发展,对产品质量的要求也日益增高。为了保证产品精度高、质量好,合理掌握零件配合尺寸精度偏差是相当重要的关键。下面就我在生产实践中的一点体会,向同志们做一介绍,供作参考。 65年,我在加工倒角机床如图1所示的零件时,球头件3压于主轴件2上, With the development of industry, the demand for product quality is also increasing day by day. In order to ensure high precision products, good quality, reasonable control of parts with the dimensional accuracy of the deviation is a very important key. The following on my experience in production practice, comrades to make an introduction for reference. 65 years, I was processing chamfering machine parts shown in Figure 1, the ball head pressure on the main shaft member 2,
