不锈钢和钛合金是广泛应用于航天、航空、能源、化工等设备的重要结构材料,用常规的机械加工方法很难实现大余量磨削及精密加工。若用电解砂轮磨削、电解研磨、电解抛光(磨料织布物)等方法,可达到精度高、表面质量好(Ra≤0.01μm)的效果,但其加工面积小,效率低,无法满足类似大型水轮机叶片、大型化工合成塔、罐等(材料均为不锈钢和钛合金)大余量磨削和精密加工要求。砂带磨削是一种比普通砂轮磨削效率高4倍以上的加工方法,其加工效率甚至超过了车、铣、刨等常规工艺。砂带磨削的“冷态磨削效应”在加工不锈
Stainless steel and titanium alloy are widely used in aerospace, aviation, energy, chemical and other equipment, an important structural material, using conventional machining methods is difficult to achieve large margin grinding and precision machining. If using electrolytic grinding wheel grinding, electrolytic grinding, electrolytic polishing (abrasive fabric) and other methods, to achieve high precision, good surface quality (Ra ≤ 0.01μm) effect, but its processing area is small, inefficient, can not meet the similar Large hydraulic turbine blades, large chemical synthesis tower, cans, etc. (stainless steel and titanium alloy materials are) grinding and precision grinding requirements. Belt grinding is a kind of processing method that is more than 4 times higher than the ordinary grinding wheel grinding efficiency, and its processing efficiency even surpasses the conventional technology such as car, milling and planing. Belt grinding “cold grinding effect” in the processing of stainless steel
