1970年我所“工具制造专用设备”调查组曾对各有关工具厂使用专用设备的情况作了普遍调查。其中包括钻头、丝锥、板牙、铣铰刀,冷锯片、复杂刀具、量具生产及备料、热处理和其它专用设备。这些资料巳于《工具技术》1971年2～3期刊登。 1972年该组又作了一次补充调查与整理。本刊从本期起将陆续刊登。本期选登的是有关钻头生产的专用机床,供参考。
In 1970, the survey team of our “tool manufacturing special equipment” conducted a general survey on the use of special equipment by various related tool factories. These include drills, taps, dies, milling reamers, cold saw blades, complex tools, gage manufacturing and stock preparation, heat treatment and other special equipment. This information has been published in Tools and Techniques, Issue 2, March 1971. In 1972 the group also made a supplementary investigation and arrangement. Publication from the beginning of this issue will be published. Selected for this issue is the production of special drill bit for reference.
