DK3220线切割机床,共有导轮、导电轮、后导轮、排丝轮等。因导电稳定轮、导电杆等的损坏,常影响生产正常进行。又因压紧螺丝挡住视线,穿丝时不容易对准二个V形槽;加工小零件时,经常会碰断导电杆和导电杆塑料套。为此,我试着改导电轮、导电杆进电为导电块进电,经一年多运行,效果良好。方法是利用原导电轮塑料套,在塑料套与内卷铜套之间开一腰形孔,用硬质合金作导电块 DK3220 wire cutting machine, a total of guide wheel, conductive wheel, the rear guide wheel, Tire wheel and so on. Stabilized by the conductive wheel, conductive rod damage, often affect the normal production. But also because of blocking the line of sight screws, threading is not easy to align two V-groove; processing small parts, often touch the conductive rod and conductive plastic sleeve. To this end, I tried to change the electric wheel, conductive rod into the conductive block into the electricity, after more than a year running, the effect is good. The method is to use the original conductive wheel plastic sleeve, open a waist-shaped hole between the plastic sleeve and the inner roll copper sleeve, and use the cemented carbide as the conductive patch
