CUT & STACK · SRJD SERIES

Cut-and-Stack Combined Line

One machine that shears, punches, pre-stacks and lays the core. Unwinding, servo feeding, hole and V-notch punching, pin-positioned pre-stacking and dual-robot lamination run as a single flow – two cores built at the same time, in full frame or E+I shape.

Reference build: SRJD400-224G

Sheet thickness0.18 – 0.30 mm
Sheet width60 – 440 mm
Max feeding speed210 m/min
Shearing burr< 0.02 mm

Why one machine instead of two

Cut and stack in one pass

No intermediate handling between the cutting line and the stacking bay: laminations go from the shear straight into the pre-stack and onto the core.

Only one V-notch unit needed

Because stacking happens in line, the machine does not need the symmetric double V-notch that a separate automatic stacker requires – a real cost saving on the punching section.

Two cores at once

Dual-robot lamination builds two CRGO cores simultaneously, in full frame or E+I shape.

Pin-positioned pre-stacking

Laminations are located by pins before the robot picks them, which is what holds the joint gap once the core is assembled.

Not sure between cut-and-stack and a separate stacker?

The choice depends on your core mix, volume and how many V-notch units you are willing to pay for. Send your lamination drawing and we will compare both routes for your own product.

Two cores at a time – does that fit your volume?

Tell us your lamination sizes, core shapes and monthly output. Our engineers calculate the cycle time on your own drawing before quoting.
