大型柴油机机体、液力传动装置的箱体、齿轮减速器箱体等零件的轴承座孔端面、孔内环槽及止口面的加工,由于被加工面的精度要求高,特别是当这些加工面距工件的端面距离较远,或采用专用镗模定位加工各种孔时,不能利用一般镗床的径向走刀机构,往往成为加工的关键,而采用本装置即能满足加工的技术要求。常见的径向走刀机构大多是将镗杆的轴向进给运动转化为刀具的径向进给运动。由于机构中的传动零件一般都要布置在空心镗杆的有 Large diesel engine body, hydraulic transmission box, gear reducer boxes and other parts of the bearing seat hole end hole hole ring and stop surface processing, due to the accuracy of the surface to be machined, especially when these processes Face distance from the workpiece far, or the use of special boring mold positioning various holes, you can not use the general radial boring machine radial approach, often become the key to processing, and the use of the device that can meet the technical requirements of processing. The common radial walk mechanism mostly transforms the axial feed movement of the boring bar into the radial feed movement of the tool. Because of the transmission components in the body are generally arranged in the hollow boring bar there
