CNC Machining PP
What is PP material and CNC machining PP parts?
PP material is the abbreviation of polypropylene, which is a common plastic material with the advantages of light weight, wear resistance, corrosion resistance, high temperature resistance, low water absorption, etc.
CNC machining of PP parts is a common manufacturing method, where CNC stands for Computer Numerical Control. This machining method uses CNC machines and PP materials to manufacture a variety of parts and products. CNC machining allows PP materials to be chipped from large blocks by rotating tools at high speeds and formed into the desired shape and size according to predetermined design specifications.

CNC machining characteristics of PP?
The CNC machining characteristics of PP material are as follows.
Less machining difficulty: the cutting force and thermal deformation of PP material are lower, so it is less difficult to process in CNC machining and less likely to produce burrs and deformation.
Lower heat deformation temperature: PP material has a lower heat deformation temperature and is easy to soften and deform at high temperatures, so the machining temperature should be controlled in CNC machining to avoid generating excessive machining heat.
Excellent cutting performance: PP material has good cutting performance and is suitable for various CNC machining methods, such as milling, drilling, turning, wire cutting, etc.
High surface finish: PP material has high surface finish after CNC machining, which is not easy to produce burrs and cracks and other problems, so it is suitable for processing various high-precision parts.
Dimensional stability after processing: PP material is suitable for processing parts with high requirements for dimensional accuracy because of its better stability and smaller dimensional changes after processing.

What are the common problems and solutions of PP material turning and milling?
The following common problems may occur in the process of turning and milling of PP material.
Chips hanging or stuck on the tool: PP material has certain stickiness, which is easy to stick on the tool or hang on the machining surface, resulting in reduced cutting effect or even tool breakage. The solution is to increase the amount of cutting fluid or use high pressure coolant to clean the cutting area.
High processing surface roughness: PP material is easy to produce burrs, thermal cracks and other defects during processing, resulting in high processing surface roughness. The solution is to use a cutting process with appropriate tool size and reasonable processing parameters, and adequate cooling of the machined surface.
Processing deformation: PP material is easy to soften and deform at high temperature, especially easy to happen during high speed turning and milling processing. The solution is to adopt low temperature processing, reduce the speed of turning and milling, increase the amount of cutting fluid, etc., and also control the heat during processing.
Fusing or hot sticking: PP material is easy to fuse or hot sticking during processing, resulting in processing difficulties or processing defects. The solution is to use cutting tools of suitable size, control the processing speed and temperature, and use cutting fluid for cooling.
Surface oxidation: PP materials are easily oxidized during processing, resulting in surface color changes or adverse chemical reactions. The solution is to use appropriate machining parameters and cutting tools, control the degree of oxidation during machining, and treat the machined surface appropriately.
To sum up, PP materials may have problems such as chip suspension, high roughness of machined surface, machining distortion, fusion or hot sticking, and surface oxidation during turning and milling, but these problems can be solved by using appropriate cutting tools, machining parameters and cutting fluids.
