Video Description

 Step-lap CRGO Core Cutting Machine


Step-lap CRGOc core cutting machine is specially designed for cutting silicon steel coils into lamination strips used in transformer cores.


Step-lap CRGO core cutting machine adopts swing shear cutting device which is similar to Georg swing shear cutting machine.


Step-lap CRGO core cutting machine is a very small machine, main body is only about 2.2m long, including centering, notching, punching and cutting.


Step-lap CRGO core cutting machine combines V-notching, hole-punching and mitre cutting togther, high automation, high efficiency. Usually one 8-hour shift can cut 1 ton lamination strips.


Step-lap CRGO core cutting machine adopts Delta PLC, touch screen (HMI), inverter, servo motor and drive, high precision, good after-sale service.


Step-lap CRGO core cutting machine adopts special carbide alloy for cutting blade and notching blade and punching tools as well. Life can be more than 2,000,000 times before grinding and more than 20 times grinds.


Step-lap CRGO core cutting machine can cut different lamination strips:



Main features of the step-lap CRGO core cutting machine:

1) Delta AC servo system plus Delta PLC professional module achieve high precision feeding, quick response, high precision positioning, low noise; Max. feeding speed 100m/min, starting & braking time is less than 10ms.

2) Full automatic finishing cutting, swinging angle, counting, cutting right angle, trapezoid, parallelogram, fish-head, etc.

3) Equipped with online punching & V notching device, high productivity

4) Cutting, punching and notching motors are inverter control, quick and low noise

5) Screw rod center positioning, driven by step motor, automatic positioning

6) Cutting blade, notching tool and punching tool are made by special ceramic alloy from Germany, long life, less burr

7) Step-lap function, max. 7 steps

8)Automatic stacking device, no error on separating different kind of lamination strips, especially step-lap cut strips.
