CNC Machining PEEK
What is PEEK material and CNC machined PEEK parts?
PEEK material stands for polyether ether ketone, a high-performance engineering plastic with excellent mechanical strength, chemical stability, high-temperature resistance and wear resistance.PEEK material is commonly used in the manufacture of high-end machinery, automotive parts, aerospace components, medical devices and other fields.
CNC machining of PEEK parts is a common machining method, where CNC stands for computer numerical control. This machining method uses CNC machines and PEEK material to manufacture a variety of parts and products. CNC machining allows PEEK material to be chipped from large blocks with high-speed rotating tools and formed into the desired shape and size according to predetermined design specifications.
Because of the complex mechanical properties and physical characteristics of PEEK materials, special machining processes and techniques are required for CNC machining PEEK parts. For example, special coolants and cutting tools need to be used during machining to ensure the stability of the process and the quality of the machining. At the same time, PEEK materials have good resistance to heat and wear, will generate more heat and cutting waste, so the need to enhance the safety of the machining process and waste disposal.

CNC machining characteristics of PEEK?
The CNC machining properties of PEEK materials depend on their physical, chemical and mechanical properties, such as high temperature stability, hardness, strength, viscosity, coefficient of thermal expansion, etc. Overall, PEEK materials can be processed by a variety of CNC machining processes, but special attention needs to be paid to the following.
Temperature control: The processing temperature of PEEK materials should be strictly controlled within the range of 250°C to 400°C to avoid adverse effects of too high or too low a temperature on material properties.
Cutting speed: PEEK material cutting speed should be slower than the general plastic materials, to avoid excessive cutting speed caused by material deformation or cracking.
Cutting tools: PEEK materials are relatively hard and will wear machining tools, so you need to use high-quality carbide tools to ensure cutting quality and machining efficiency.
Coolant: During the processing of PEEK material, the workpiece and cutting tool should be cooled with the appropriate coolant to prevent material overheating and tool wear.
Precision control: Due to the high coefficient of thermal expansion of PEEK material, it is necessary to strengthen the precision control during CNC machining to ensure the dimensional accuracy of the final machined part.

PEEK material turning and milling of common problems and solutions?
PEEK material is a high-performance engineering plastics, which has high heat resistance, high strength, high stiffness and other excellent properties, but there are some common problems in the process of turning and milling, as follows.
Part surface burrs or burrs: PEEK materials are prone to burrs or burrs during processing, affecting the quality and accuracy of the parts.
Solution: you can properly adjust the cutting speed, depth of cut and feed and other processing parameters to avoid excessive cutting temperatures and cutting forces; use high-precision tools and fixtures, as well as appropriate lubricants, can reduce the generation of burrs and burrs.
Part deformation: PEEK materials are susceptible to thermal expansion and contraction during processing, resulting in part deformation, which affects machining accuracy and quality.
Solution: coolant can be used for cooling to reduce the processing temperature; appropriate to reduce the cutting speed and depth of cut to reduce the generation of cutting heat; the use of rigid fixtures to fix the workpiece to avoid workpiece deformation.
Serious tool wear: PEEK materials have high hardness and rigidity, easy to wear the tool, resulting in increased cutting forces, increased surface roughness, shortened tool life and other problems.
Solution: You can use high-quality tools, such as tungsten steel tools, polycrystalline diamond tools, etc., to improve cutting efficiency and tool life; use the appropriate cutting parameters, such as cutting speed, feed and depth of cut, to avoid excessive tool wear.
