CNC Plasma Cutter
Manufacturer: A2 MechShop, HyperTherm
Model: CNC Plasma Cutter Gantry, Model 45 Plasma Cutter
Maker Works’ CNC plasma cutter combines the cutting abilities of a HyperTherm 45 plasma cutter with a precision CNC gantry system built at the A2 MechShop. It can cut intricate shapes out of sheet metal from very thin gauges to over 1/2″ thick. Hardness of material does not matter. LinuxCNC is used as the CNC control software, and a hardware torch height controller continuously monitors torch height. Use SheetCam to convert DXF files (generated by Inkscape, AutoCAD, CorelDraw, Adobe Illustrator, etc.) for use on the CNC plasma cutter.
|Plasma Cutter||Modified HyperTherm 45|
|Maximum thickness||3/4″ (1/2″ recommended)|
|Maximum speed||380 inch/minute|
|Kerf width||0.030″ to 0.060″ (depends on materials, etc.)|
|100% duty cycle||32A|
|50% duty cycle||45A (10 minute interval)|
|Cutting area||greater than 48″ x 48″|
- Cuts without regard to hardness of material
- Cuts any conductive material
- Minimum heat-affected zone (HAZ)
- Edges often require minimum clean-up
No hazardous materials–e.g., galvanized steel, zinc-plated.
Projects with many start/stops will increase wear on the consumable tip.
Sheet metal up to 1/2″ (or thicker, with care).
