Machinery & Equipment

JF75G series high speed punching line is suitable for manufacturing motor rotor and microelectronic etc.
Features:
? Combined prestress frame structure and prestress of four screws, which meanas 2 times of nominal pressure and better rigidity
? 8 surface guided gib,adjust shut height thread hydraulic lock,which is high precision
? Dynamic balance structure and import counter balancer, which means better dynamic precision
? The main shaft adopts multi-bearing points and imported rolling bearing, which will enhance the rigidity and moving steadity of the press, reduce the total clearance and generated heat
? Forced cooling, good lubrication condition
? Infinitely variable speed, touch screen man-machine interface is easy for operating.
? Microcomputer control system and few peripheral electrical elements which means high stability.
? User can disassemble the board of the press, which is easy for maintenance.
