我国第一台每分钟可加工600个钢球的冷镦机械——ZG32-8型高速钢球自动冷镦机,最近在齐齐哈尔第二机床厂通过部级鉴定,并已投入批量生产。这种新型钢球自动冷镦机将传统设计夹持器固定在滑块上改为固定在机床上,从而消除了滑块导轨间隙对制件精度的影响,使加工精度比现有国产通用同类冷镦机提高10倍。它采用了无级调速电机加工钢球毛坯的速度可调,最高加工速度为每分钟600个,比目前普遍使用的同类冷镦机的加工速度提高4倍多。
China’s first cold-heading machine capable of processing 600 steel balls per minute - ZG32-8 high-speed steel ball automatic cold heading machine, recently passed the ministry-level appraisal at Qiqihar No.2 Machine Tool Plant and has been put into mass production. This new ball automatic cold heading machine will be fixed on the traditional design holder fixed to the machine on the slide, thus eliminating the slider rail clearance on the workpiece accuracy, the processing accuracy than the existing domestic generic Cold heading machine increased by 10 times. It uses a variable speed motor machining steel ball blanks adjustable speed, the maximum processing speed of 600 per minute, than the current common use of the same cold heading machine processing speed increased more than 4 times.
