Full Automatic Step-lap Transformer Core Cutting Machine

Product name : compact of compact full automatic step-lap transformer core cutting machine

Full Automatic Step-lap Transformer Core Cutting Machine   is specially designed for cutting silicon steel coils into lamination strips for transformer cores, welding machine cores, and reactor cores.
This machine is specially designed with a swing shear for different angle. The angles, hole position, V notching position and cutting length can be pre-set in the PLC, full automatic.
A full automatic lamination separating & stacking device is optional.
Lamination strips can be cut by this machine:
