在现代机器制造业中没有任何一台机床、压力机或种类不用工具、卡具或冲模就能够有效地工作。这时设备的生产效率越高,所采用工具和卡具应当越完善和越精密。这种工具制备(工具装备是刀具、量具、卡具、冲模等的总称,後皆同此意。译者)的价值很高,但它会使设备生产效率大大提高 No machine tool, press or type in modern machine manufacturing can work effectively without tools, fixtures or dies. At this time, the higher the production efficiency of the equipment, the more sophisticated and precise the tools and fixtures used. This kind of tool preparation (tools and equipment is the general name for tools, measuring tools, fixtures, dies, etc., all of which are the same after this. Translator) is of high value, but it will greatly increase the efficiency of equipment production.
