Y7520W万能螺纹磨床是我厂磨削丝锥、塞规、环规、精密螺杆、滚刀的关键设备。在磨削精密螺纹塞规时,经常出现火花不匀的现象,使工件中径出现锥度,产品质量不易保证。为此,我们利用机床调整机会,从机床的静态精度和热变形影响的两个方面找原因,并采取相应的措施,解决了螺纹磨床磨削螺纹时中径超差的问题。一、调整机床1.砂轮架横进给运动(1)砂轮架导轨滚柱接触应均匀。对100件滚柱直径进行测定,误差小于0.002。(2)导轨接触应良好。检查导轨接触斑点,并调整导轨的几何精度。即:导轨在垂直面内的直线性为
Y7520W universal thread grinder is our factory grinding tap, plug gauge, ring gauge, precision screw, hob the key equipment. Grinding precision thread plug gauge, the phenomenon of uneven sparks often appear, so that the diameter of the workpiece taper, product quality is not easy to guarantee. To this end, we use machine adjustment opportunities, from the machine’s static accuracy and thermal deformation of the two aspects to find the cause, and take appropriate measures to solve the thread grinder thread diameter when the over-tolerance problem. First, adjust the machine tool 1. Wheel carrier cross feed motion (1) wheel carrier rail roller contact should be uniform. 100 roller diameter determination, the error is less than 0.002. (2) rail contact should be good. Check the rail contact spots and adjust the rail geometry. That is: the linearity of the guide rail in the vertical plane is
