Modern machines with multiple constantly moving mechanical parts, CNC Machine Tools need to be regularly cleaned and maintained to keep them running optimally.įailure to clear away dirt, material and other debris could result in a build-up which over time can result in inaccuracies in machining or even machine failures. Comprehensive user manuals and training, motion sequencing, and operation of the machine should be provided to new operators by the machine suppliers or experienced operators on the shop floor. To resolve these errors, it is important for new operators to be adequately trained in the different ways in which CNC machines can be programmed. These may come from a lack of understanding of the different G and M codes used for the controller, wrong set-up, or inputting the wrong data variables into the CNC controller. #2 Errors in ProgrammingĪs highly sophisticated equipment controlled by CNC computers, much of the issues which arise in CNC machining often comes from programming. To resolve this, it is important to choose the right tool and setting for the job and material. It may also be caused by the wrong dimensions of the tool for the job at hand in terms of the sizes, quality or match with the material. Poor material finishes could be due to either bluntness in the tool used, or improper feed speed ratio. Extensive tool wear may result from this error. This could be seen as rough edges, cutter marks on the surface, raised marks, or burn marks on the material’s edges or corners. #1 Using the Wrong Cutting Tools / SettingsĬhoosing the wrong cutting tool for the job may often result in poor quality material finishes. CNC Machine Tool Mistakes – The Big Fourįrom our experience, the bulk of the problems faced by machinists in using CNC lathes, milling machines and multi-axis machining centres revolve around four main issues. In this article, we will try to answer some of the most common problems and challenges faced in CNC machining, and suggest ways for you to solve them. These run the entire gamut – from burn marks on the finishes of machined parts, power supply failure, to the “jamming” of different moving parts or inaccuracy in machined parts. What should you do when you encounter an issue with your CNC machine tool? Should you try to fix it yourself, call the supplier of the machines, or Google for answers?Īs one of Asia’s leading CNC machine tool manufacturer, we’re aware of the common problems and issues that may occur during the machining process.
