一、前言车床溜板箱移动的操作力,是机床的一项质量指标。JB2278—78标准中规定:车床重量小于2吨,操作力小于6公斤;大于2吨,操作力小于8公斤。目前,中型以上的车床大都装有快速电动机,但是,在加工过程中,毕竟离不开频繁的手动操作。刀架移动沉重,意味着机床工作性能差,影响加工精度和光洁度,也加重了工人的劳动强度。 I. INTRODUCTION The operating force for the movement of the carriage of a lathe is a quality indicator of the machine tool. JB2278-78 standard provides: lathe weight less than 2 tons, the operating force of less than 6 kg; more than 2 tons, the operating force is less than 8 kg. At present, most medium-sized lathe equipped with fast motor, but in the process, after all, is inseparable from the frequent manual operation. Heavy knife movement, which means poor performance of machine tools, processing accuracy and finish, but also increase the labor intensity of workers.
