The machines are used for punching shear the cold crimped engine bed with the thickness of 1.2-2.5mm, the width of 2000mm, and Material strength of 450N/mm². The specifications of punching shear are surveyed by the bit of TB5-20 mesh grid plate: if the TB, TL is increased, the punching shear strength is increased.

In order to not damage components for the excess load. The nominal tonnage is 63T. If TB, TL are reduced, the punching shear strength surpasses the nominal tonnage, you can reduce the material thickness and width to resolve.

The machines are used for punching all kinds of expand plate mesh in construction, common hardware, window and door, machine protecting etc.

Feeding mechanism passes the chain link by the main engine directly, the movement accurate is reliable.

The times of feed mechanism punching shear start from 0, it can shear at will scope.
