SA7612螺纹磨床我厂过去生产过一些,根据使用单位所反映的问题,我室于1973年把横进给机构、砂轮主轴和砂轮修正器等几个部件作了一些改进,从改进设计制造后的情况来看,性能良好,其改进情况简述如下: 1.横进给机构: 原横进给机构系采用凸轮、杠杆和梯形丝杆螺母付结构,据用户反映,定位精度不准,铲磨及锥磨机构也较重,现采用液压油缸和滚珠丝杆螺母付结构。
SA7612 thread grinder used to produce some of our factory in the past, according to the problems reflected by the use of units, our room in 1973 to the infeed institutions, wheel spindle and grinding wheel corrector and several other parts made some improvements, from improving the design and manufacture of Situation, the performance is good, the improvement is summarized as follows: 1. Cross feed mechanism: The original horizontal feed mechanism is the use of cams, levers and trapezoidal screw nut pay structure, according to user feedback, positioning accuracy is not allowed, shovel grinding And cone grinding mechanism is also heavier, now using hydraulic cylinders and ball screw nuts to pay structure.
