我们在多年的内燃机生产实践中深深地感到曲轴磨床的砂轮修整是提高曲轴加工的产量和质量的关键,同时又是一个棘手的问题,因为大多数内燃机曲轴被磨削部位的形状决定了对砂轮既要修整外圆,又要修整两侧的过渡圆弧,并且要求外圆,肩面和两侧圆弧准确相切、圆滑过渡,采用切入式磨削的曲轴磨床所要求的砂轮修整精度就更加严格。 We have deeply felt in many years of internal combustion engine production that the grinding wheel dressing of crankshaft grinding machines is the key to improving the output and quality of crankshaft machining. At the same time, it is also a thorny issue because most crankshafts of internal combustion engines are shaped by grinding parts. Grinding wheel both to trim the outer circle, but also trimming the transitional arcs on both sides, and requires the outer circle, shoulder and arc on both sides of the exact tangent, smooth transition, the use of plunge grinding grinding wheel grinding wheel required dressing accuracy Even more stringent.
