MainProperties | Main Features
High rigidity
1. A high rigidity and precision framework, welded with steel plates, and heat treated to eliminate pressure inside the bed.
2. The load on the structural components is uniform and the rigidity is balanced.
Stable and high-precision
The friction parts such as the crankshaft, gears, and gear shafts are all hardened and heat treated before grinding, resulting in extremely high wear resistance and balance, and stable performance.
Reliable and safe operational performance
The clutch/brake device is highly sensitive, combined with a dual solenoid valve and overload protection device, to ensure the accuracy and safety of the operation and stop of the punch slide.
Production automation and labor-saving
Can be paired with any automatic feeding mechanism to operate automated production, reduce costs, and improve efficiency.
Center of gravity balance
1. The transmission center tends to align with the overall center of the machine, ensuring the accuracy and stability of stamping.
2. This machine adopts two slider balancers to ensure that the machine maintains balanced operation.
Sliding block adjustment mechanism
Adjusting the confidentiality up to 0.1mm makes production safer and faster.
environment protection
Advanced design concepts, low noise, low consumption, and energy saving.
