3.High efficiency, choice different speed upon different pcb. Vlow=150mm/s, vhigh=300mm/s
4.High accuracy, better safety; machine operation is simple and it is easy to maintain;
5.The blade has special treatment so that long lifetime;
6.During operation, keep pcb and the circular blade is moving to assure quality.
Three spec
