The precision of a plasma cutting machine has always been a top concern for users. Based on years of experience and practical use, the consensus is that the accuracy is generally ±0.5mm, similar to that of CNC cutting machines worldwide. But why does an error occur?
It seems logical that a cutting machine could achieve an accuracy of 0.01mm with no errors at all—but this is not how it works. Here’s a brief explanation of the factors affecting cutting accuracy:
1. The repeatability positioning accuracy of a CNC cutting machine is usually less than 0.1mm. However, during the actual cutting process, the size of the cutting nozzle can cause some deviation. This deviation is typically determined through trial cuts, and once set, mass production can be carried out efficiently.
2. Another source of error comes from thermal deformation of the metal plate itself. Even if there's a small movement during cutting, kerf compensation can handle it. However, when cutting different thicknesses, unpredictable deformation may occur. Mastering this requires experience from multiple cutting sessions.
Many first-time buyers of CNC cutting machines have high expectations because they are not fully aware of the limitations of cutting precision. In reality, such expectations are often unrealistic. Therefore, when purchasing a cutting machine, it's essential to clearly define the desired level of precision. Proper understanding and usage of the CNC cutting machine will help maximize its performance.
