Abstract:

An ultra-high speed grinding of stainless steel was conducted in order to avoid the wheel loading and grinding burn out,to improve efficiency, and to optimize the process. The influences of grinding parameters, including wheel speed, the depth of cut and feed rate, on the grinding force, the roughness and surface morphology were analyzed under high/ultra-high speed grinding conditions, and wheel geomorphology was detected. The results indicate that the optimized feed rate and the depth of cutting can ensure the higher efficiency and better surface integrity.

Key words: high speed grinding, stainless steel, roughness, grinding force, grinding wheel

摘要：

为避免不锈钢磨削中发生砂轮堵塞,减轻磨削烧伤的程度,提高加工效率,优化加工工艺,对不锈钢进行超高速磨削试验研究。在高速/超高速磨削条件下,研究了不同砂轮线速度、工件进给速度和进给量对不锈钢磨削的磨削力、表面粗糙度和表面形貌的影响作用,并检测了不同工况下的砂轮表面状态。研究结果表明,不锈钢在超高速磨削状态下,选择合理的工作台速度和磨削深度能有效提高加工效率,同时又能保证磨削质量。
