CNC Plasma Cutting Tables: We have a model to suit your workshop…
Take control of your metal parts production with your own Plasma Table / Plasma Bed
With an “in-house” CNC plasma cutting table, you can cut what you want, when you want… instead of waiting for a contractor to do it in their time, not yours.
At Weldclass, we offer a range of CNC plasma cutting tables including Weldclass Cutforce series, PlasmaCAM and Samson to match your specific needs. All are trusted brands in the industry, so you know you’ll get years of great and reliable service whichever product you choose.
What is a CNC plasma table used for ?
CNC Plasma tables are used in metal fabrication and manufacturing industries for cutting components from flat metal sheet or plate, including steel, stainless-steel, aluminium & other metals.
How does a CNC Plasma Table work ? | What is a CNC Plasma Table ?
In short, a plasma table is the main component in a CNC plasma system used for cutting shapes from flat sheets of steel or metal. To perform this task, a plasma table must be coupled with other machinery. The main components of a CNC plasma table system and their functions are as follows;
- Table: Supports the sheet/plate metal and can include additional features such as water beds
- Gantry: Part of the table, holds & moves the torch. Gantry position is controlled by the computer/software along it’s X-axis (across the table) and Y-axis (along the table)
- Plasma Torch: Is attached to the gantry & does the actual cutting. Compressed air is forced through the torch nozzle and an electric arc is introduced to heat the metal and create ionized gas or plasma which then pierces the metal
- Plasma Cutting Machine or power source: Powers the torch
- Air Compressor / Air Supply: Feeds into the plasma cutter and torch
- Computer System: normally a PC/computer, screen and associated accessories, this hosts the operating software
- Software: Used to design the parts to be cut (CAD), Create & process cutting files (CAM), and operate the table (CNC). CAD drawings can also be imported from other computers / systems / files.
What materials can I cut with a CNC plasma ?
Plasma will cut any electrically-conductive materials, including steel, stainless-steel, aluminium and most metals. CNC plasma tables are used for a wide range of metalfab applications where versatility is critical, such as fabrication shops, manufacturing, automotive repair and restoration, training centres, and more.
How accurate is CNC plasma ?
This depends on a few factors. First the design of the table; Weldclass Cutforce series plasma tables are accurate to within 0.2mm, thanks to the direct rack & pinion drive mechanism. Next is the accuracy of the plasma arc, which will vary depending on the quality and condition of the plasma system, torch and consumable parts. We recommend allowing between 0.5-1.0mm for plasma arc deviation, noting that worn consumables and poor air quality will result in higher deviation. One of the reasons we use Hypertherm plasma machines is because they offer unmatched performance, accuracy and parts durability.
Should I consider CNC Laser, Waterjet or Oxy ?
Great question! Each system has their place. For general metalfab applications with materials of up between 1mm & 30mm thickness, CNC Plasma offers the best combination of affordability, fast cutting (productivity), low running costs and versatility.
