在C630车床上车削具有台阶的轴类、套类零件时,由于该车床没有纵向走刀刻度盘,很不方便。轴向尺寸须先用钢皮尺划好尺寸线,每车完一个台阶还要停车检验,既耽误时间又易产生误差。为此,我们在C630车床上安装了具有300mm刻度的纵向走刀刻度盘,又在刻度盘后盖上刻有游标,使纵向走刀量精确到0 .1mm,从而提高生产率,并保证加工质量,而且结构简单,改装及使用都很方便,现简介如下:
In the C630 lathe turning stairs, sets of parts, because the lathe does not have a vertical knife dial, very inconvenient. Axial dimensions must be first dimensioned with steel tape ruler, each car finished a stop inspection, not only the time and error prone. To this end, we installed on the C630 lathe with a vertical scale 300mm graduated dial, but also engraved with a cursor on the back cover of the dial, so that the amount of longitudinal cutting precision to 0 .1mm, thereby increasing productivity and ensure the quality of processing , But also simple structure, modification and use are very convenient, are as follows:
