在没有座标镗床的工厂,对孔距要求较严的零件如钻模上的钻模板等,往往只能在车床或铣床上根据划好的线来加工。这样加工的结果很难达到精度要求。现在介绍一种采用先定位后加工的方法,来加工钻模板上的各孔,一般 In a factory without a coordinate boring machine, parts that are more porous to the hole, such as a drilling template on a drilling die, can often only be machined on a lathe or a milling machine based on the line drawn. The result of such processing is difficult to achieve accuracy requirements. Now introduce a method of using the first positioning after processing, to drill each hole on the template, the general
