Main Features
-
The whole machine has adopted imported PLC centralized control, and imported safety double valve control is applied to the gas circuit, to realize inch, single and continuous punching.
-
The key parts such as slider, guide rail, worktable plate, connecting rod, and flywheel are all cast with resin sand. Compared with common clay sand casting. the surface roughness and dimensional accuracy are improved effectively.
-
Electrical control is applied to filling height for JH21 products of 60 tons or above.
High-quality configuration and all the key components and parts such as pneumatic components, electrical apparatus elements, sealing elements, and buttons are imported.
