PEEK (Polyether Ether Ketone) is a high-performance engineering thermoplastic that is widely used in CNC machining due to its excellent properties. Here are some key aspects of PEEK materials for CNC machining:
Mechanical Strength: PEEK has high tensile and flexural strength, making it suitable for demanding applications.
Chemical Resistance: It is resistant to a wide range of chemicals, including acids, bases, and organic solvents.
Thermal Stability: PEEK maintains its properties at high temperatures, with a melting point around 343°C (649°F).
Wear Resistance: It exhibits low friction and excellent wear resistance, which is beneficial for components that experience constant movement.
Dimensional Stability: PEEK has low moisture absorption and good dimensional stability, even in humid environments.
Biocompatibility: It is biocompatible, making it suitable for medical and pharmaceutical applications.
Aerospace: Components such as brackets, housings, and insulators due to its lightweight and high strength.
Automotive: Parts like gears, seals, and bushings because of its durability and wear resistance.
Medical: Surgical instruments, dental devices, and implants owing to its biocompatibility.
Electronics: Insulators, connectors, and semiconductor parts due to its excellent electrical properties.
Oil and Gas: Seals, valves, and compressor components, given its chemical resistance and durability.
When machining PEEK, certain considerations ensure optimal results:
Cutting Tools: Use carbide or diamond-coated tools to handle PEEK's toughness and prevent excessive tool wear.
Coolant: Employ air or water-based coolants to manage heat generated during machining, as excessive heat can affect the material properties.
Speeds and Feeds: Adjust machining speeds and feed rates to prevent overheating and to achieve a smooth surface finish.
Fixturing: Ensure proper fixturing to avoid material deformation due to clamping forces.
Post-Machining: PEEK may require annealing post-machining to relieve internal stresses and improve dimensional stability.
Several manufacturers provide PEEK materials in various grades, including:
Victrex: Offers a range of PEEK grades tailored for different applications.
Solvay: Known for its KetaSpire® PEEK products.
Evonik: Provides VESTAKEEP® PEEK materials.
Ensinger: Supplies TECAPEEK® PEEK grades.
Each supplier offers materials with specific enhancements, such as improved wear resistance, higher strength, or better processability, to suit particular needs.
In summary, PEEK is a versatile material for CNC machining, providing high performance across a range of applications due to its unique combination of mechanical, thermal, and chemical properties.
