What is the answer to How can we help diagnose a CNC machine problem?
A CNC machine is an electro-mechanical device used to manipulate and control machine tools and devices using computer programming. In other words, controllers program the CNC machine to tell the machine shop tools what to do. The name CNC stands for computer numerical control.
How Does CNC Machining Work?
The basic function of CNC machining is to take a blank piece of material, such as a block of plastic or a similar item, and transform it into a finished product. The CNC machine does this by telling the machine shop tool exactly how to move, and exactly what pieces of the material to cut away.
CNC Machine problems
No matter how fast and efficient CNC machines is, they’re not always dependable. They develop problems and need maintenance just like any other type of machine or tool. And like any other tool, there are certain things you can do that might inadvertently damage these machines. There are also definite steps you can take to keep them in good working order. Maintaining these machines is something many companies do not do and then of course, they do not work. This is where we come in! At Greasley Electronics we repair many of them!
While there are certainly any number of problems that can lead to issues and errors within CNC machining, some problems are more commonplace than others. These problems are also ones that are easy to overlook and easy to misdiagnose.
Relays are a common component of CNC machines. Each relay board takes an I/O signal of 24VDC or lower and converts it into a signal that’s usually either 24VDC or 110VAC.
Almost all relay boards are equipped with LED lights that turn on when the machine needs an output. When you see a light blink on, it means the output has reached the board and must be applied to the relay on the board. If the circuit is not fused correctly, this is where some problems could occur. Sometimes tampering with it, however your skill, is not the best solution!
As time-saving as it is to be able to diagnose the problems in your machine and fix them yourself, there will always be situations where the problems go beyond employee capabilities to fix. When that happens, the team at Greasley Electronics are ready to step in and help get your machine back to work.
