我们在硬质合金刀具及模具的制造中,使用人造金刚石砂轮取代了绿色碳化硅砂轮,取得了较好的效果。下面谈谈我们在应用中的几点体会。一、在普通万能工具磨床上也能获得满意效果。我们把直径200mm的平形砂轮装在老式M5M万能工具磨床上。该磨床主轴瓦经过精心刮研调整,使主轴跳动量在0.01mm以内。磨削硬质合金铰刀外圆,将一把六个齿直径30mm左右的双联饺刀0.8mm的粗磨余量磨去,只需要30min。这种效率是
In the manufacture of carbide cutting tools and molds, we used synthetic diamond grinding wheel instead of green silicon carbide grinding wheel and achieved good results. Here to talk about our experience in the application. First, the general universal tool grinder can also get satisfactory results. We put the diameter of 200mm flat grinding wheel mounted on the old M5M universal tool grinder. The grinder main bearing after careful research to adjust the spindle runout in less than 0.01mm. Grinding carbide reamer cylindrical, a six teeth diameter of about 30mm double dumplings 0.8mm rough grinding margin worn away, only 30min. This efficiency is
