摘　　要：现代电脑横机移圈针要求具有较高的精度和一致性,以适应电脑横机高速化的发展趋势以及对移圈针使用寿命越来越长的要求。针对以上问题,提出一种新的加工工艺。以加工中心为加工平台,配合PLC专用自动化夹具,优化刀具类型、夹持方式和加工参数,采用油雾的冷却润滑方式,从而实现了移圈针沟槽的高精度化和高自动化加工。经批量加工检验,其加工精度可达到±0.015 mm,超过传统±0.025 mm的加工精度,批量加工的尺寸一致性达到使用要求,表面粗糙度也较传统工艺提高了1个级别。High precision and consistency are demanded for transfer needles of computerized flat knitting machines in order to adapt to the rapid development trend of the machines and to meet the requirement of longer service life of needles.Therefore,this paper introduced a new processing technique,which took machining center as the processing platform,utilized a special automatic fixture with PLC,and consisted of cooling and lubrication with oil-mist,optimization of tool types,gripping style and processing parameters,thus realizing high accuracy and automatic processing of needle grooves.Results of batch processing showed that the machining precision could reach ± 0.015 mm,better than traditional precision of ± 0.025 mm,and the dimensional consistency met operating requirements.Moreover,surface smoothness was upgraded when compared with that by traditional technique.
