上海中国纺织机械厂在技术革命运动中,制成了加工四方孔和六方孔用的钻头。这种钻头虽然在某些工厂早已制成,但不如该厂完善。用钻头加工方孔和六方孔在精度、光洁度和生产率方面虽然不如拉刀和推刀,但在单件、小批生产和设备条件受限制的工厂中却是相当合理的。特别是拉刀和推刀所不能加工的不通孔以及插刀所不能加工的小方孔,采用钻头加工更能显出优越性来、由于这种钻头加工范围广,对于中小型工厂特别适用。本文附有较完整的工作图,可供大家参考。
Shanghai China Textile Machinery Factory in the technical revolution movement, made of processing four-hole and six-hole drilling bits. Although this bit has long been made in some factories, but not as perfect as the factory. Square and hexagonal holes drilled with bits are not as accurate, smooth and productive as broaches and knives, but are reasonably reasonable in single, small batch and equipment-constrained plants. In particular, broach and push the knife can not be processed through the hole and the knife can not be processed small square hole, the use of drill more shows the superiority of the work, due to the drill a wide range of processing, particularly suitable for small and medium-sized factories. This article is accompanied by a more complete work chart, for your reference.
