Our Capabilities

CNC Punching

Punching is produced quickly and efficiently on our Trumpf TC500R – CNC punching center. We use computer-assisted part nesting software, which provides the best material utilization. With automatic tool-changing options and high positioning speeds, the machine produces multiple punching, marking and embossing services. For performing automated tool sharpening, we use the specialized Trumpf Quicksharp Punch Tool Sharpener. Apart from delivering high accuracy in every punching operation, the tool sharpener improves the tool life and therefore reduces tool-replacement costs. In addition, our machine taps holes without operator intervention.

Punching abilities:

  • Countersunk or extruded  holes
  • Louvers
  • Assembly tabs
  • Pre-punched holes/knockouts
  • Beading  for part strength


We punch parts for different industry OEMs. Mainstay uses a variety of materials including stainless steel,  aluminum and copper.
