Sheet Metal Punching

At Stevens Rowsell we operate a Trumpf Trupunch 2020 with full automation.

Punching in terms of producing holes or cutting out pieces of sheet metal is done by a process known as shearing.

The positioning, movement and processing of the sheet is synchronised by a CNC program written using special software by an engineer.

Aside from punching openings, our machines can also be used for creating contours by a process called 'nibbling' or can be used to create special shapes by a process called 'forming'.

The punching station uses an electro-hydraulic punching head for consistently high punching power and has a rotatable single tool adapter for lowering the number of tools needed and decreasing the machine and tooling set up times. With the appropriate tooling the punching head also allows for a wide range of forms to be produced such as extrusions, louvers, beads, flanges and hinges.

The machine is support by an integrated and compact sheet handling system for automated loading and unloading of sheets 2500 x 1250mm.

We operate a two function multi too system which consist of several single tools combined in one holder. This considerably increases the number of tools available and improves efficiency thus reducing cost.

Our punch has a tapping function which allows us to form threads in mild steel, stainless steel and aluminium without producing chippings.
