我们认为,先上仿型线切割,再上程序控制,这对于线切割工艺在生产中发挥作用见效较快。我们在自制仿型线切割时,原设计方案是采用双电机慢速走丝,线的移动速度为5～15毫米/秒。提高走丝速度是一个关键,我们改为单电机快速走丝,走丝速度在6～15米/秒范围内无级可调,提高了加工稳定性和生产率。我们认为快速走丝的优点是: 1.电蚀物可由高速移动的电极丝及时排出切割区,避免了因电蚀物堵塞而造成的短路。
We believe that the first imitation of the line cutting, and then on the program control, which for the wire cutting process in production play a more effective. When we make a copy of a self-made profiled wire, the original design solution is to use a double motor to slowly move the wire at a moving speed of 5 to 15 mm / s. It is a key to improve the speed of wire drawing. We change to a single motor to take the wire quickly and take the wire speed steplessly adjustable from 6 to 15 m / s, which improves the processing stability and productivity. We believe that the advantages of fast wire walking are: 1. Electro-erosion materials can be promptly removed by high-speed wire electrode cutting area, to avoid short circuit caused by the clogging of electrical erosion.
