Machining PEEK: Tips, advantages & applications
Polyether ether Ketone (PEEK) is a thermoplastic polymer that exhibits excellent properties such as high-temperature resistance and chemical resistance. It is one of the most widely used engineering plastics due to its superior mechanical, thermal, and chemical properties. PEEK is a semi-crystalline thermoplastic material that can be machined using various techniques such as machining, drilling, milling, grinding, and sawing. This article discusses the tips, advantages, and applications of machining PEEK.
Tips for Machining PEEK
When machining PEEK, there are several tips to keep in mind to ensure a successful process. First, it is important to select the right grade of PEEK for the job. Different grades of PEEK have different properties and tolerances, so selecting the right grade is essential. Second, the cutting tools should be made from high-grade materials such as carbide or diamond. Third, the cutting speed should be kept low to avoid overheating the material. Fourth, it is important to use coolant or lubrication when machining PEEK to reduce friction and heat buildup. Finally, cooling the material with air jets or water during machining will reduce the risk of burning or melting the material.
Advantages of Machining PEEK
Machining PEEK offers several advantages over other materials. First, PEEK is a strong and durable material that can withstand extreme temperatures. Second, PEEK has excellent chemical resistance, making it suitable for use in chemically aggressive environments. Third, PEEK is lightweight and easy to machine. Fourth, PEEK is corrosion-resistant and can be machined into components with complex shapes. Finally, PEEK is a low-cost material that provides good value for money.
Applications of Machined PEEK
Machined PEEK has a wide range of applications in many industries. It is commonly used for parts and components in the aerospace, automotive, medical, and electronics industries. PEEK is also used in the manufacture of high-performance bearings, gears, and valves. In addition, machined PEEK is used in food processing and packaging equipment due to its non-toxic and non-allergenic properties. Finally, machined PEEK is used in sealing and insulation products.
Conclusion
In conclusion, PEEK is an excellent material for machining due to its superior properties and versatility. It is a strong and durable material that can withstand extreme temperatures and chemicals, making it suitable for a wide range of applications. The tips and advantages discussed in this article should be taken into consideration when machining PEEK to ensure a successful process.
