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. It features a swing shear for various angles. Lamination shape, hole position, V notching position, and cutting length are all pre-set in the PLC for full automatic operation.

Main Features

✓ Delta AC servo system and PLC module achieve high precision feeding, quick response, and low noise. Starting & braking time is less than 10ms.

✓ Supports cutting various shapes: right angle, trapezoid, parallelogram, fish-head, etc.

✓ Equipped with online punching & V notching devices for high productivity.

✓ Cutting, punching, and notching are driven by servo motors for better reliability and speed.

✓ Carbide alloy blades provide long life (over 1.2 million times before grinding) and minimal burr.

✓ Step-lap function supports up to 7 steps, with each step consisting of two laminations.
