在一般工件表面上滚花并不难,但要保证轴上滚花部位与轴各台阶的同轴度就不是那么容易,特别是小批量加工。针对这个问题,我们制作了自动定心的滚花工具,使用该工具,滚花轴的同轴度、尺寸公差、滚花精度均满足图样要求。 滚花工具的结构原理如图所示,将刀体8压在刀 Knurled on the general workpiece surface is not difficult, but to ensure that the axis of knurled parts and the axis of the concentricity of the stairs is not so easy, especially in small batch processing. In response to this problem, we made a self-centering knurled tool, the use of the tool, knurled shaft concentricity, dimensional tolerances, knurling accuracy to meet the design requirements. Knurling tool structure principle as shown, the knife body 8 pressure knife
