Finished enclosure projects are punched by CNC punching machines. These are cutting down the desired forms from metal sheets. Punching machines automatically move sheets, punching various kinds of holes, including: rectangle, circle, ellipse, and others - depending on the needs. The device also allows to punch pre-embossed openings by simultaneously cutting the desired shape and and embossing the sheet. In addition, there is the possibility of stamping serial numbers / names / symbols / logos on a given part of the enclosure. The use of CNC punching machines ensiures precise cutting and repeatability of elements.
