在线切割机床上,早期采用煤油为工作液,其优点是不易断丝,但生产率低、切割面光洁度差、易燃并散发出有毒气体。后来改用一般乳化液,虽能提高生产率和光洁度,但容易断丝。通过实践,我们认识到线切割生产率、光洁度、钼丝损耗等均与线切割机床的性能和 On-line cutting machine tools, the early use of kerosene as the working fluid, the advantage is not easy to break, but low productivity, cutting surface finish is poor, flammable and emit toxic gases. Later switched to the general emulsion, although it can improve productivity and finish, but easy to break the wire. Through practice, we recognize that the wire cutting productivity, finish, molybdenum wire loss, etc. are all related with the performance of wire cutting machines and
