POM CNC turning common problems and solutions

Here are some common problems and their solutions:

Tool wear: Due to the relatively low wear resistance of POM material, the tool is easy to wear. Solutions include using better wear-resistant tool materials, adjusting cutting parameters, increasing tool coatings and so on.

Cutting temperature is too high: POM’s thermal conductivity is poor, easy to produce high temperatures during processing, affecting the cutting performance and processing quality. Solutions include using coolant to cool the tool and workpiece, controlling the cutting speed and feed rate, and avoiding excessive heating.

Chip handling problems: POM chips are easily adhered to the tool and workpiece, improper handling is likely to cause problems such as tool jamming. The solution includes choosing appropriate chip handling equipment and methods.

Poor surface quality: POM’s machining surface is prone to burrs, scratches and other problems, affecting the processing quality. The solution includes choosing suitable cutting tools, optimizing cutting speed and feed rate, and carrying out appropriate surface treatment.

Machining accuracy problems: POM has a high coefficient of thermal expansion, and dimensional deviations may occur during machining. Solutions include controlling the processing temperature, making appropriate compensation, and calibrating the machine tool.

Excessive cutting force: The high strength of POM makes it generate large cutting force on cutting tools. Solutions include optimizing the cutting path, choosing the right tool and cutting parameters, and reducing the cutting force.

Programming errors: Since the machining characteristics of POM are different from those of metal, errors may occur during programming. The solution includes a deep understanding of the characteristics of POM and reasonable programming and adjustment.
