在镗床上用锥柄立铣刀进行铣削加工时很容易掉刀,不管铣刀装入镗杆后用多大力往里敲,也会在铣削过程中突然脱出来,造成工件报废,操作者的精神也高度紧张,不到万不得已,不愿在镗床上进行铣削工作,极大地限制了镗床的使用范围。 与铣床装刀方法相比较,镗床上掉刀的原因是铣刀与刀套及刀套与镗杆之间没有拉紧螺栓紧定,仅凭锥面摩擦力传递切削力,而铣刀在铣削时产生的轴向拉力及交变径向力很容易将铣刀从锥套里拔出来。
In the boring machine with taper shank end milling cutter is very easy to cut the knife, regardless of the milling cutter into the boring bar with more vigor in the knock, it will suddenly emerge in the milling process, causing the workpiece scrapped, the operator’s Spirit is also highly tense, less than a last resort, do not want to milling on the boring machine, which greatly limits the use of boring machine. Compared with the milling machine tooling method, the boring machine off the knife because the cutter and the sleeve and the sleeve and the boring bar between the tensioning bolt tight, only the cone friction force transmission cutting force, while the milling cutter Axial tension and radial force generated when the cutter is easy to pull out from the sleeve.
