When deciding on which CNC plasma cutting system to buy, you must consider a few critical elements like the CNC control, the fume control system and the mechanical components.
This essentially guides the motion control of the CNC plasma cutting system and converts the program for cutting to electrical instructions that direct the cutting speed and direction of the plasma machine. The CNC control also guides the operation of the other peripheral devices and the height control of the cutter.
The mechanical components of the CNC plasma cutter are the moving parts that include the torch carriage, gantry and Z-axis. These are the elements that carry out the actual physical work needed to produce the required parts.
Fume Control System
This is required to manage the fumes and smoke generated during the plasma cutting process. Most plasma cutting systems have a downdraft table that removes the smoke and fumes using exhaust ducting, fans or by using a water table that absorbs the fumes and smoke.
When it comes to industrial CNC plasma cutters, the CNC controls make use of an industrial-grade computer that is equipped with machine control and internal motion control software. The drive motors, height control, plasma cutters and other components are all controlled by a range of input and output instructions. The CNC controller gets inputs from the CAM software as well as the plasma machine operator. These instructions are converted to electrical signals that control all the functions of the plasma cutting system.
The industrial CNC controls are fabricated and engineered in such a way that they are very rugged and can operate extensively in rough, electrically noisy and dirty environments. Nevertheless, CNC plasma cutting has many advantages:
Higher Efficiency Levels
CNC plasma systems offer greater efficiency and are easy to use and require minimal training for the operators to handle.
Superior Precision and Accuracy
CNC plasma cutting systems are very accurate and they assure precision in cutting as pre-set measurement specifications are programmed into the computer control system before the cutting process.
Suitable for Cutting Many Materials
The CNC plasma cutting process can be used to get high-quality, precise cuts on a variety of materials including ferrous and non-ferrous metals. Metals that are even up to 6 inches thick can be cut using CNC plasma cutting effortlessly.
Higher Productivity and Faster Cuts
The CNC plasma cutting process does not need any complex adjustments and the cutting speed is also faster which results in increased productivity.
In the past, CNC plasma cutting was used only by high-volume large industrial setups that were able to afford the expensive price tags that accompanied these superior cutting systems. However, in recent years, innovations in technology and the advantages of CNC cutting have enabled CNC plasma cutting to become more affordable and easily accessible to a wide variety of industries.
