过去,机修钳工在大修机床时,为配好机床上移动部件的楔铁,其斜面是用人工刮研方法加工的。特别是加工较长钢料楔铁斜面,不仅劳动强度大、效率低,而且质量也差。针对以上关键,经过机修车间广大职工的共同努力,制成了一台万能楔铁磨具(附图),实现了楔铁斜面以磨代刮,经初步试用,取得了较好的效果。
In the past, when the machine repairman overhaul the machine tool, the wedge iron used to move the part on the machine tool was machined by the manual scraping method. In particular, the longer steel wedge iron processing, not only labor-intensive, low efficiency, but also poor quality. In response to the above key, through the joint efforts of the vast numbers of workers in the mechanic workshop, a versatile wedges grinding tool (with photos) was made to achieve wedge iron scraping on behalf of scraping scraps. After preliminary trial, good results were achieved.
