Punch processing

Punch processing of flat sheet or plate is commonly performed using one of two machine formats. First, stand-alone punch machines, known as turret punches, offer automated operations including punching, contour cutting (nibbling), and tapping. Because of their versatility, turret punch machines are highly effective as punch processing tools. The process delivers highly accurate holes, without exposing workpieces to damage from heat-affected zones.

A second machine format integrates punch capability into an X-Y plasma, laser, or plate processing machine. By bringing these processes together, fabricators can enjoy superior productivity thanks to reduced material handling time and improved part quality. In addition, these integrated machines save on floor space.

Combination plasma/punch and combination laser/punch typically feature a traditional cutting table with the added ability to reposition the workpiece to a dedicated punching station. (These machines are sometimes referred to as reposition machines.)

Plate processing machines combine cutting, punching, drilling and other tools in one highly versatile machine.

Typical uses include:

  • Electronics structural components and cases
  • Small appliance hardware
  • Structural bolt-hole applications

Process technologies used:

  • Punching
  • Tapping
