At Humble most sheet metal cutting operations are performed using high speed, multi-tool CNC punch presses. Punching is performed by moving a sheet of metal using X and Y drives between the top and bottom tools of a punch. The punch or top tool mates with the die or bottom tool, cutting simple shapes such as (but not limited to) squares, circles, and rectangles from the sheet. The shape of the part is made by cutting many holes at high speed.  A typical sheet metal part such as an electrical box could be cut in a matter of seconds.

Modern CNC turret punches can hold over 50 different tools in the turret.  Turrets also have a number of special tool holders which are designed to rotate the tool incrementally allowing for cutting complex angles and curves. 

Humble has a broad selection of punches and dies in inventory and a tool list is available upon request.
