机床主轴内孔的精加工,历来成为生产关键之一。以往采用三爪卡盘夹持,搭中心架等方法,加工起来比较困难。为此,我们对该零件的加工过程,对影响加工精度的每一个环节进行了较全面的分析,设计了一种可调主轴磨架,既能适用于不同长度、不同直径零件的加工,又能方便经济地得到主轴零件的高精度。 The machining of the inner hole of the machine tool spindle has always been one of the key production points. In the past using three-jaw chuck clamping, centering frame and other methods, processing more difficult. To this end, we have carried out a more comprehensive analysis on the processing of the part and the impact on the machining accuracy of each link, designed an adjustable spindle mill, both for different lengths, different diameter parts processing, and It is convenient and economical to get the high precision of spindle parts.
