一般外圆磨削时,冷却液是送到工件和砂轮间的空隙处,粗磨工件时冷却液则不够充份。 一磨削时.由於磨料和工件摩擦使局部发生高温,砂轮变钝时温度还会升高,但在修整砂轮以後,工件的温度便显著降低,这已用自动进给的嵌入磨外圆法证实了。实验证明加工余量和相同的同样工件磨到 需 General cylindrical grinding, the coolant is sent to the gap between the workpiece and the wheel, rough grinding the workpiece is not sufficient coolant. A grinding. Due to abrasive and workpiece friction to local high temperature, the wheel will become dull when the temperature will rise, but after dressing the wheel, the workpiece temperature will be significantly reduced, which has been using automatic feeding embedded cylindrical method proved. Experiments show that the same machining allowance and grinding the same workpiece required
