Computer Numerical Control (CNC) Machines can best be described as complex, reliable and highly durable. However, they can start to develop complications as they age. As such, attention to detail is required when troubleshooting and repairing.
In order to fix the malfunctions, it’s essential to have a great understanding of the working of the various components. We discuss the three most common CNC machine problems experienced.
Programming Errors
Improper programming is a common problem prevalent with the newest employees and results in undesired cutting issues. Due to scanty expertise, the new members of staff tend to already face challenges tracing the source of the problem, let alone correcting it.
While it may not be the incompetence of the machine, most developers often overthink the malfunction. Although one may tend to take it for granted, a reboot of the CNC machine and restarting the process usually solves the malfunction.
Also, as you may well know, the most integral part of the CNC machine is the controller. If you note any errors, before anything else, check the controller parameters and any vital signs.
Usually, new employee training on the use of set G Codes and M Codes for cutting is all that is needed to prevent programming-related CNC machine malfunctions.
Poor or Lack of Maintenance
Most issues you run into are usually under your control when using CNC machines. Therefore, you need to make sure to have regular maintenance. Lack of or improper maintenance often results in a major problem of overheating.
Make sure you unclog the filters and AC units of the dirt and debris that cause internal overheating. Be sure to wipe off the cutting fluids and metal shavings frequently to prevent the contamination of the machine.
Improper Tools/Improper Settings
On the edges and the corners of the finished material, inspect the machine for burns, scratches, or distortions. The marks on the end product indicate several things: slow feed speed, blunt tools, improper tool positioning, and insufficient coolant or lube. Fixing this problem requires you to simply adjust the cutting tool and replace the blunt tool or lubricate it.
