在普通镗床上用立铣刀或键槽铣刀进行铣削加工时,如不采取特殊措施就无法象在铣床上那样用拉杆紧固立铣刀。切削过程中往往产生铣刀松动现象(因为立铣刀的刃带是螺旋线状,切削时会产生一个将铣力拔出的力);轻者使切削过程中断,重者会损坏刀具或使工件报废。为解决这个问题、我们设计了一种镗床用的铣刀杆,结构如图所示。 制造刀杆时,刀杆与镗床主轴的配合间隙采用配
Milling on an ordinary boring machine with an end mill or a keyway mill can not be used to tighten an end mill with a tension bar, as in milling machines, without special measures. Cutting process often produce loosening of the milling cutter (because the cutter end of the spiral is the shape of the cutting will produce a milling force pulled out); light to cut off the cutting process, the weight will damage the tool or make Workpiece scrapped. In order to solve this problem, we designed a boring mill cutter bar, the structure shown in Figure. When manufacturing arbor, arbor and boring machine spindle with the use of clearance
