What is a CNC plasma cutter in gantry design?

 

Gantry with tool stations, guideways and cutting table

Plasma cutting systems in gantry design consist of a steel gantry, a so-called gantry beam, driven on both sides and mounted on guideways. The tool stations (plasma torch, drilling support, scanner, etc.) are mounted on this beam. Thanks to the solid construction, they can be positioned vibration-free and accurate to a few hundredths millimetres. A plasma cutting table is positioned within the guideways, on which the cut parts are placed and processed.

Plasma power source and gas supply for the plasma cutter

In order to initiate and perform the cutting process in a plasma cutting system, the corresponding periphery is required. A power source supplies the necessary power for the plasma system, the gases required for the plasma beam are provided by a gas supply.

Filter system

The dusts and particles occurring during cutting with a plasma system are collected either by an extraction system directly at the plasma torch or at the plasma cutting table and the air is cleaned in a filter system.
 

Touch display with machine control

A main monitor is used to control the CNC plasma cutter and program the cutting tasks for the plasma system.
 

 

Advantages of CNC cutting systems …

… compared to other cutting methods (laser, waterjet, oxyfuel)

  • High economic efficiency through fast and precise plasma technology with unrivalled cost-benefit ratio
  • High level of automation
  • Extremely flexible when cutting all electrically conductive materials
  • High cutting speeds of the plasma torch when processing thin and medium material thicknesses (significantly faster than oxyfuel and waterjet)
  • Compared to the laser, shorter processing times for medium and higher material thicknesses
  • Nearly post-processing free cutting results
  • Multi-torch operation possible for fast parallel cutting
  • Only solution for the cutting of aluminium materials and various high-alloy steel grades when processing materials in the thin and medium thickness range

… in gantry design compared to robot cutting machines

  • Individual width and length of the working area from 1 to more than 20 metres wide and 1 to more than 50 metres long
  • Depending on the working area, simultaneous loading and unloading during the cutting process is possible (pendulum operation)
  • Shorter processing times due to the option of using several gantries on one system
  • Higher cutting speeds
  • Much more flexible through the use of multiple processing options (2D cutting, bevel cutting, marking, drilling, etc.)

 

… in gantry design compared to manual plasma cutters

  • High cutting quality
  • Almost no post-processing
  • Multifunctionality: Several processing options can be realized on one system
  • Automation capability

Which materials can be processed with a plasma cutting machine?

In principle, all conductive materials can be processed with a CNC plasma cutting machine. In practice, CNC plasma cutters are used to process the following materials, among others: Mild steel (fine-grained steel, Hardox), stainless steel (V2A), chrome-nickel steel (V4A), aluminium, copper, brass, titanium, armour steel. The typical cutting range of a plasma system is between 1 mm and 50 mm here the cutting results are of high quality and economically most efficient.

Multifunctionality & automation

Today, a modern plasma cutting system enables much more than just 2D and bevel cutting of sheets, pipes, profiles and domes. Drilling, countersinking, tapping, marking and labeling are also among the options that can be realized on a CNC plasma cutting machine in addition to the cutting technology. Furthermore, technologies for scanning can be integrated, e.g. for reading barcodes or for automatic determination of the position of metal sheets.

Strengths of MicroStep plasma cutting systems

For its gantry-guided plasma systems, MicroStep relies on a steel gantry, that is stiffened and driven with AC servo motors on both sides, for high dimensional accuracy and reproducibility of the cutting results with the best dynamics and strong driving power. Due to the modular design of the CNC cutting machines, different technologies can be combined and different geometries (sheet metal, pipe, profile, beam, dome) be processed on one plasma cutting system. Due to the automatic calibration of the used tools with the patented calibration unit ACTG®, MicroStep plasma cutting machines achieve permanently precise cuts and, thanks to the best components, can be used for a long time even in three-shift operation. With the MicroStep QualityHole® hallmark you can also be sure that all decisive factors for cutting small holes and fine contours have been optimized.

Plasma cutting systems in various industries

CNC plasma cutting systems are used in all sectors and industries in which materials such as mild steel, stainless steel and aluminium in the medium material thickness range are required and factors such as high-quality cutting results at high cutting speeds and simultaneously low cutting metre costs are decisive for the cutting process. A selection of industries and possible fields of application for MicroStep plasma cutting systems is given below:
