PPS CNC turning common problems and solutions

Here are some common problems and their solutions:

Tool wear: The high hardness and rigidity of PPS material makes the tool easy to wear. Solutions include choosing high hardness tool materials, using tool coatings with better wear resistance, and adjusting cutting parameters to reduce tool wear.

Cutting temperature is too high: PPS has poor thermal conductivity, easy to produce high temperatures during processing, affecting the cutting performance and processing quality. Solutions include the use of coolant to cool the tool and workpiece, control the cutting speed and feed rate, avoid excessive heating.

Cutting deformation: PPS is a relatively hard plastic, but in the CNC turning process, may still produce cutting deformation. The solution includes choosing suitable cutting tools and cutting parameters, controlling the cutting speed and feed rate to minimize cutting deformation.

Poor surface quality: the processing surface of PPS is prone to burrs, scratches and other problems, affecting the processing quality. The solution includes choosing the right tool, optimizing the cutting speed and feed rate, and carrying out appropriate surface treatment.

Machining accuracy problems: PPS has a low coefficient of thermal expansion, but dimensional deviations may still occur. Solutions include controlling the machining temperature, making appropriate compensation, and calibrating the machine tool.

Excessive cutting force: PPS is prone to large cutting forces, especially at high speeds. The solution includes optimizing the cutting path, selecting appropriate tools and cutting parameters, and reducing the cutting force.
