我厂工艺试验室于一九六九年曾改装C620-1为半自动程控车床,但由于林彪反革命修正主义路线的干扰和破坏,一度下马。一九七四年,在批林批孔运动的推动下,重建了工艺试验室,组织了三结合小组,在学习兄弟厂经验的基础上,改进设计,反复试验,经过六个月的艰苦奋战,于一九七五年四月改装成功了半自动程控车床。试车结果表明,机床性能良好,工作稳定,结构紧凑,改装简便。
In 1969, the Craft Laboratory of our factory converted the C620-1 into a semi-automatic controlled lathe. However, it was disrupted and disrupted by the counter-revolutionary revisionist line of Lin Biao. In 1974, under the auspices of the Campaign for Approval of Borells and Punch holes, the Craft Laboratory was rebuilt and a three-in-team was organized to improve the design and test on the basis of learning Brother Factory’s experience. After six months of hard work , In April 1975 converted a successful semi-automatic program-controlled lathe. Test results show that the machine performance is good, stable work, compact structure, easy modification.
