Compact Full Automatic Step-lap Transformer Core Cutting Machine

Clear photo of main section of compact full automatic step-lap transformer core cutting machine:

This 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:

Main features of compact full automatic step-lap transformer core cutting machine:
