在矿山机械行业中，经常运用齿条传动，而直齿齿条尤为常见。目前齿条的加工仍停留在比较初级的加工方法阶段。加工前工艺人员考虑更多的是在切齿后如何检查上，即采用齿形样板和齿距样板分别来检查齿形和齿距精度。切齿时采用指形铣刀和齿距量块，没有更准确、更科学的精度控
In the mining machinery industry, rack drives are often used, while straight-toothed racks are particularly common. At present, the processing of the rack still stays in the primary processing stage. Before processing staff to consider more is how to check after cutting teeth, that is, using tooth-shaped template and pitch model to check the tooth profile and pitch accuracy. The use of finger cutter and pitch gauge when cutting teeth, there is no more accurate and more scientific precision control
