我厂制造大批圆盘铣刀,车削铣刀毛坯的外圆时,要把铣刀装在心轴上以铣刀的内孔定位进行加工。因为用内孔定位,所以对内孔的要求就比较严格,以前加工铣刀内孔是先钻孔然后再搪孔或铰孔,这样不仅生产效率低,而且加工后孔的尺寸也不一致,常常出现跟心轴不能很好配合的现象。后来,经过大家研究,设计一种钻铰组合刀具,如附图所示。经过使用证明用钻铰组合刀具加工,可以节省许多辅助工时,提高生产效率2倍以上,并且保证了产品质量。
I plant a large number of disc cutter, milling cutter blank cylindrical, the cutter should be installed on the spindle to the milling cutter bore positioning processing. Because with the hole positioning, so the requirements of the hole is more stringent, before the milling cutter hole is the first hole and then bored or reaming, so not only low production efficiency, and processing the hole size is inconsistent, often Appear with the mandrel can not be well with the phenomenon. Later, after all, we designed a drill-hinge combination tool, as shown in the attached figure. After the use of proven combination of drilling and drilling tools, you can save a lot of helper hours, improve production efficiency more than 2 times, and to ensure product quality.
