机床的程序控制是世界尖端技術之一,可以用各种方式方法來進行机床的程序控制,如凸輪控制,紙带控制,磁帶控制,光电控制,数字控制等等。磁帶、光电、数字等控制需用电子管放大,改裝费用較大,使用寿命不長,維护保养不易,在目前我國中小型企業內普遍采用有一定的局限性;凸輪控制只用在自动车床和半自动车床中,因为它們每当變換一种加工另件时要制造一套孲猛馆喕蜓?既貴又费时,制造
Machine tool program control is one of the world’s cutting-edge technology, you can use a variety of ways to machine program control, such as cam control, tape control, tape control, optical control, digital control and so on. Tapes, optoelectronics, digital control required to use electronic tube amplification, modification costs more, the service life is not long, maintenance is not easy, at present our small and medium-sized enterprises generally have some limitations; cam control is only used in automatic lathes and Semi-automatic lathe, because they are each time a change in the processing of other parts to create a set of 孲 蜓 蜓 dragonfly 蜓 ?
