Metal Punching

Red Box Engineering use a Muratec CNC Wiedeman Centrum C2500, which has 17 tool stations it also has a multi tool station. This, therefore, allows us to have 29 tools in the machine at any one time, which is ideal for all sheet metal punching tasks.

Red Box Engineering stock a wide range of tooling for this machine, whilst bespoke tooling can made to customers requirements.

We use Radan Radpunch to program our machine. Radpunch is a fast, modern programming application designed and written by Radan to assist a programmer in transferring data from CAD to NC code.

Red Box Engineering based in Southampton, Eastleigh but provide welding and CNC punching throughout the UK.

This includes Totton and throughout Hampshire and all surrounding areas.

Sheet Metal Punching Process

Sheet Metal PunchingSheet metal punching is a cutting process in which material is removed from a piece of sheet metal by applying a great enough shearing force.

CNC Punching can be used to produce holes and cutouts of various shapes and sizes.

The most common punched holes are simple geometric shapes (circle, square, rectangle, etc.) or combinations thereof.

The die, located underneath the sheet, has a cutout in the shape of the desired feature.

Punches and dies of standard shapes are typically used, but custom tooling can be made for punching complex shapes.

The punch press drives the punch downward at high speed through the sheet and into the die below.

There is a small clearance between the edge of the punch and the die, causing the material to quickly bend and fracture.

The slug that is punched out of the sheet falls freely through the tapered opening in the die.

This process can be performed on a manual punch press, but today computer numerical controlled punch presses are most common.

A CNC punch press can be hydraulically, pneumatically, or electrically powered and deliver around 600 punches per minute.
