由于机床卡盘承受很大的夹紧力和切削力,卡盘零件极易磨损。磨损后的卡盘主要缺陷是工作精度超差和夹紧时卡爪呈喇叭口。因此,降低加工精度、削弱了夹紧的刚性。常用的一种综合修理方法,是对已磨损的卡盘卡爪进行自身修磨。修磨工艺的关键,是卡爪修磨时的夹紧方法。由于受到卡盘结构的限制往往 As the machine chuck to withstand a lot of clamping force and cutting force, chuck parts easy to wear. The main defect of the worn chuck is that the working claw is flared when the working accuracy is out of tolerance and the claw is clamped. Therefore, the machining accuracy is reduced, and the rigidity of the clamp is weakened. A commonly used method of comprehensive repair is to self-polish already worn chuck jaws. The key to grinding process is the clamping method when clamping claw grinding. Due to the limitations of the chuck structure often
