在成批生产中、对普通孔的加工尚缺乏经济有效的手段。多工位钻孔组合机床通用性差;钻削中心价格贵;普通钻床虽灵活、但停留在一刀一序的低效状态,尤以换刀耗费大量工时,劳动强度大、加工精度低。而机电部近期颁布的有关文件都提到要发展转塔系列钻床,以满足成批生产多工序加工的
In mass production, the processing of ordinary holes is still a lack of cost-effective means. Multi-station drilling machine combination of poor versatility; drilling center expensive; ordinary drilling although flexible, but stay in a knife a sequence of inefficient state, especially in exchange for a large number of working hours, labor-intensive, low precision. The Electrical and Mechanical Services Department recently promulgated the relevant documents are mentioned to develop turret series drilling machine to meet the batch production of multi-process processing
