We offer punch plasma combination machines to meet a wide range of needs.

More Parts Per Hour. Period.

starting at $379,000

Producing complex, thick parts with multiple steps can take a lot of time when done on a series of machines. That’s why fabricators worldwide turn to Piranha-Whitney Punch Plasma Combination machines to produce three times as many parts per day, at one third the cost.

Proven ROI

Even as laser technology advances to cut thicker parts faster, the Piranha-Whitney combination consistently beats lasers, plasma machines, and water jet machines when it comes to ROI. Our Punch Plasma Combination will put more parts on the floor at the end of the day in steel, stainless steel, and aluminum, than any other process.

A Piranha-Whitney punch plasma machine also streamlines your operations, providing cutting, punching, countersinking, embossing and drilling capabilities – all on one machine, with one set-up. Integrating your drilling operations greatly increase efficiency and reduce costs.

 

Advantages That Make a Difference

Advantages of our Piranha-Whitney plasma-punch machine include:

  • No warped or misshapen parts: The punching cylinders on our combination machine are fully hydraulic. Our Reactive Stripping process actually grips the material, and pushes and pulls it through the material, leaving your parts flat and highly accurate. Many of our competitors use a turret style machine, which actually hammers the parts through the material. This can leave your parts warped or misshapen, leaving you with the hours and expense of rework.

  • Better edge quality: Our counter-balanced cutting head rides on the surface of the material following the contour of the plate, keeping the distance precise throughout the cutting process.

  • All the tools you need: Piranha-Whitney’s Automatic Tool Changer opens wide – up to 2-1/2″ – so that high forms or non-flat sheets can be run reliably. The Tool Caddy can add 21 additional tools to make our combination machines even more productive.

  • Ability to run long parts: The Piranha-Whitney plasma-punch combination machines only move the plate in one direction, while the machine moves over the plate in the other. This means that our machines can run very long parts—up to 24 feet. Because of Piranha-Whitney’s unique design, we can run these parts with a large clamp spread and never torque the X-axis. The result is longer parts that are more accurate.

  • The plate is always in place: When you’re running parts that are longer than the axis of the machine, the Piranha-Whitney combination machine has an automatic repositioning system. Cylinders come down and hold the plate, the work clamps release, move to a new location, and re-grip the sheet. This allows you to run twice the length of the X-axis, meaning you don’t need to invest in a larger, longer machine just because you have a part that needs it. The Piranha-Whitney combination machine can handle it all.

  • Easy-clean slag chamber: Because the Piranha-Whitney combination machine only moves the plate in one direction and the machine in the other, we can capture all your slag material in a chamber underneath the cutting-head. This keeps the cutting area clean, and your shop stays free of smoke.

  • Never mix up parts again: Many parts can look very similar and be difficult to identify for internal use. The Piranha-Whitney inkjet marking system can alleviate this problem by putting identifying numbers on parts as they come off the machine. This system can do alpha and numeric characters, as well as graphics anywhere on the plate.

  • Do more in fewer steps: In other machines, forming processes like countersinking would have to be done with a cutting tool. Piranha-Whitney combination machines first punch a hole, then use a special tool and form that counter-sink around the pilot. Our machines can make consistent countersinks very quickly. We can also do plow-bolt holes, louvering, lance and form, half-shear forms, and any type of form you can do on a turret press.

Benefits Vs. LASER and Plasma

Lower Cost per Part

  • Sometimes a difference of 50% or more of the value-added content

External Cuts

  • Plasma cutting is faster than laser cutting
  • Latest plasma-cutting technology yields cut quality comparable to laser
  • Plasma cutting is a more robust technology – not as susceptible to material chemistry and surface finish

Internal Features

  • Punching is faster than piercing and contouring
  • In thicker material, there is no concern with heat build-up as with laser
  • Quality of a punched feature is more precise; this makes punched holes conducive to processes such as:
    • Tapping
    • Using self-tapping screws
    • Press-fit fasteners and bushings
  • Holes that are pierced and contoured with a laser-cutting machine may not be suitable for these operations
  • Punching leaves no lead-in blemishes
  • Laser-cutting may leave some holes not completely cut, resulting in secondary drilling or hammering to remove the slugs or parts

Other Features

  • Punching technology allows formed features to be produced, avoiding secondary operations.
    • Countersinks
    • Dimples
    • Tread
    • Louvers
  • Holes that are pierced and contoured with a laser-cutting machine may not be suitable for these operations
  • Punching leaves no lead-in blemishes
  • Laser-cutting may leave some holes not completely cut, resulting in secondary drilling or hammering to remove the slugs or parts
  • Optional attachments such as drilling and tapping produce even more features
    • Small holes less than 50% of material thickness
    • Tapped holes

Other Materials

  • Aluminum and Stainless Steel can be processed at speeds comparable to that of mild steel
  • Excellent quality of aluminum parts make combination machines a perfect match for aluminum fabrications.
    • Trailer industry
    • Military vehicles
    • Rail car
    • Dump trucks
  • Recent developments in stainless steel plasma cutting technology provide high quality oxide-free processes

Lower Cost per Part

  • Sometimes a difference of 75% or more of the value-added content
  • Overall operating costs are significantly lower.
    • Plasma consumable life is greatly affected by the number of starts and stops. By punching internal features, consumable life is greatly improved
  • Automated small part removal feature gets parts out of skeletons as they are cut
  • Available optional material handling features on plasma-punch machines (plate loading/ skeleton removal) create much higher utilization rates than standalone plasma cutting tables

External Cuts

  • Better drive system with high acceleration results in more accurate parts with better corner definition
  • Smoother drives provide dross-free cutting

Internal Features

  • Punching yields higher quality holes–plasma cut features cannot be used in some applications
  • No blemishes at the lead-in / lead-out in punched features
  • Able to punch diameters less than material thickness; plasma is normally limited to 1.5 x material thickness

Other Features

  • Punching technology allows formed features to be produced, avoiding secondary operations.
    • Countersinks
    • Dimples
    • Tread
    • Louvers
  • Optional attachments such as drilling and tapping produce even more features.
    • Small holes less than 50% of material thickness
    • Tapped holes

Other Materials

  • Small plasma cut features in stainless steel and aluminum have marginal accuracy and definition due to lag of plasma stream and excessive blemishes from lead-ins. Punched holes provide accurate holes with no blemishes
