1. J31 series presses adopt steel-welded conbined structure (J31-250C base is foundry). The base, left and right uprights and crossbeam is connected through four tightening bolts, connection between the cross beam and slide adopts guide pillar and guide pillar bush structure(except630B)
2. The series presses adopt floating disk friction clutch-brake, controlled by imported safe double valve, reliable performance, high connection and long life.
3. In the slide there is import hydraulic overload protecting device (in 630B is an overload protecting formed of a shear plate).
4. Centralized lubricating system of thin oil (in 630B is centralized lubricating system of thick oil)
5. The presses are controlled by imported touchscreen, PLC and double look control system.
