立式钢坯修磨机的磨头砂轮进给控制机构,一般都采用板式开关或旗型开关。由于板式开关和旗型开关动作时均有一个摆角,造成一段空程,所以钢坯修磨后在头部或尾部有一段漏磨,给修磨质量带来不良影响。有的立式钢坯修磨机使用光电管控制磨头进退,但由于光电管安装在砂轮修磨处的近旁,磨削时的强火花易使光电管误动作。钢坯的漏磨问题长期未能解决。 苏州冶金机械厂在研制YLM-Ⅰ型双面
Vertical billet grinding head grinding wheel feed control mechanism, the general use of plate switch or flag switch. As the plate switch and the flag switch action has a swing angle, resulting in a period of empty trip, so the billet grinding head or tail in a period of leakage, to the grinding quality adversely affected. Some vertical billet dresser with photocell control grinding head advance and retreat, but the photoelectric tube installed in the grinding wheel near the grinding Department, strong sparks grinding easy to make the photoelectric tube malfunction. Billet abrasion problems have long been unable to solve. Suzhou Metallurgical Machinery Factory in the development of YLM-Ⅰ-type double-sided
