CNC Tube Punching Machines
Criterion provides CNC Tube Punching and Tube Notching Machines that permit the end user to automatically punch and notch distortion free hole patterns in long pieces of tubing.
Due to the material and dimensional variations in commercial grade welded steel tubing and aluminum extrusions, it is very difficult to punch and notch a distortion free hole using an ID mandrel if the hole is located 18 inches or more from the tube end.
Distortion free holes that are located this distance from the tube end are not normally created by traditional punch, notch and die techniques. Most often they are drilled and deburred, or laser cut.
Using proprietary punch, notch and die tooling techniques, Criterion has developed CNC Tube Punching Machines and Tube Notching Machines that can be programmed to punch and notch distortion free hole patterns in rounds and various shapes of tubing and extrusions.
Applications have ranged from automotive airbag fill tubes, to display rack tubing, fence posts, appliance burner tubes, manifold tubes, gas grill frames, video screen frames, heat exchanger tubes, office furniture, etc. Tube lengths vary from 1 to 20 feet.
This CNC Tube Punching Machine is capable of punching 2 tubes per cycle. Tubes are each punched on both sides simultaneously.
This CNC Punching Machine punches up to 34 distortion-free holes on a "teardrop" style aluminum automotive step rail.
This CNC Tube Punching Machine forms slot and hole patterns on all four sides of a rectangular tube. Two tubes are processed per machine cycle.
This 2-Axis CNC Tube Punch Machine is capable of punching complex hole patterns. All Criterion CNC Tube Punch Machines are similar in design concept and modular construction but the machine specifications vary.
Our Heavy Duty CNC Punch Machine can continuously punch 1" diameter holes in a 2.75" diameter x .165" wall tube.
