Therefore, we recommend that you use carbide tooling for short runs of machining common PEEK grades. #2 Use the Carbide and Polycrystalline ToolingĪll PEEK grades are abrasive to cutting toolsㅡwhich means they can cause damage, wear, or removal of tooling material during cutting operations. One thing to note, though: you might have to perform an additional annealing process if you plan to subject your PEEK workpiece to long stretches of machining time. But before you take the plunge with machining these parts, you must relieve built-up stress through annealingㅡwhich is a heat treatment process that involves heating the plastic to a predetermined temperature, holding it for a certain period, and then cooling to room temperature.Īnnealing increases the level of crystallinity and decreases built-up internal stresses of PEEK parts, preventing the likelihood of surface cracks during CNC cutting operations. PEEK plastics typically come in rods, plates, or injection molded blanks of various sizes. 5 PEEK Machining Tips #1 Anneal PEEK Plastics Before Machining

This makes them especially useful in custom medical implants, such as articulating joints. However, in addition to all of these properties, medical-grade PEEK plastics are also chemical resistant and biocompatibleㅡwhich means they don’t have harmful effects on the human body. The medical-grade PEEK possesses all of the mechanical properties of industrial-grade PEEK. Some industrial-grade PEEK plastics are reinforced with carbon fiber, which offers higher strength and abrasion resistance than conventional PEEK plastics. Components made from industrial-grade PEEK are used in the aerospace, automotive, chemical, electronics, and energy industries. The industrial-grade PEEK is a strong, abrasion-resistant thermoplastic with a low coefficient of friction and high impact strength. Fabricating PEEK Plastic Parts: Gensun Can Help.#2 Use the Carbide and Polycrystalline Tooling.#1 Anneal PEEK Plastics Before Machining.The sliding behavior always depends on the overall sliding system, and on parameters like sliding partner, load, sliding speed, surface roughness, temperature and so on. The fillers carbon fiber and graphite make TECAPEEK PVX black a superior bearing grade with improved thermal conductivity. The better the thermal conductivity of the part, the faster the heat is dissipated and overheating can be reduced. In order to avoid thermal overload of a bearing, the resulting frictional heat should be dissipated as quickly as possible from the sliding surface of the bearing. Because of these excellent sliding characteristics, they are used in gears, bearings, sliding bearings, and many other applications. PEEK is used where conventional materials (POM, PA / Nylon etc.) would be beyond their limits. With this combination of criteria, this bearing grade material can be used in harsh environments of 100 to 300☌. Improved heat dissipation (reduced frictional heat).Still, many applications call for special PEEK bearing grades as TECAPEEK PVX black, containing a multiple filler system (graphite, carbon fiber and PTFE), to fulfill a combination of requirements: Unfilled PEEK natural is the most balanced material in high temperature environments, where non-lubricated sliding and non-contamination is required. PEEK bearing materials with excellent heat resistance and durability Polyetheretherketone is often viewed as one of the engineering thermoplastics that tends to command a high price, however experienced users have come to realise the added value that PEEK materials bring by offering the possibility of manufactured parts that are lighter, stronger and able to survive longer periods under harsh conditions. PEEK plastic is often used in hot water or steam environments because it maintains physical properties such as flexural and tensile strength at a high level despite the severe environment. Parts manufactured from high temperature plastic PEEK polymer can also operate at temperatures up to 260☌ (480☏) and have a melting point around 341☌ (646☏). PEEK is a unique semi crystalline, engineering thermoplastic that also offers excellent chemical compatibility. It is extruded in sheet, rod and tube that may use Victrex® PEEK 450G or Solvay KetaSpire® KT-820 polymer. PEEK material (chemically known as polyetheretherketone) is manufactured by Ensinger in standard stock shapes for machining.
