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.
