PEEK CNC Machining

PEEK, or Polyether ether ketone, is a high-performance engineering thermoplastic with exceptional mechanical and chemical resistance properties that remain consistent at high temperatures. PEEK is ideal for a wide spectrum of CNC machining applications where thermal, chemical, and combustion properties are critical to performance.

In a CNC machining service company, PEEK would be machined using specialized cutting tools and parameters to account for its unique properties. The process typically involves programming the CNC machine with precise instructions to cut the PEEK material into the desired shape and dimensions. This can include a variety of operations such as milling, turning, drilling, and more.

PEEK Materials Properties

PEEK, or polyether ether ketone, is a high-performance engineering thermoplastic and part of the PAEK family of materials.

Generic PEEK
Peek GF30

Generic PEEK Properties

PEEK is a type of plastic that's really tough and can handle a lot of heat, more so than most other plastics we use. It's also not a fan of water, which means it doesn't soak it up easily. This is good because it means PEEK can stay strong and keep its shape even when it gets wet or is used in damp places.

Tensile Strength, Yield (MPa) Elongation at Break (%) Hardness (Shore D) Heat Deflection Temperature (°C) Glass Transition Temperature (°C)
275-410 65-120 1.5-110 182-210 143-155

USP Class VI PEEK Properties

USP Class VI PEEK is a specialized grade of PEEK that meets stringent biocompatibility standards, making it suitable for medical applications that require a high degree of interaction with the human body. Like standard PEEK, the USP Class VI grade maintains excellent resistance to chemicals, which is important for medical devices that may be exposed to various drugs or cleaning agents.

PEEK GF30 Properties

PEEK GF30 is a type of PEEK (Polyether ether ketone) plastic that has been reinforced with 30% glass fibers. The addition of glass fibers enhances several properties of the base PEEK material, making it more suitable for certain applications, including automotive, aerospace, electrical, and medical, for components that require high strength, stiffness, and thermal stability. PEEK GF30 can be machined more easily than pure PEEK, allowing for the creation of complex parts and components with precision.

PEEK CNC Machining FAQs

  • What is PEEK in CNC machining?

    PEEK, or Polyetheretherketone, is a high-performance engineering thermoplastic often used in CNC machining for parts that need to withstand high temperatures, chemicals, and harsh environments.

  • Why is PEEK preferred for CNC machining?

    PEEK is preferred due to its excellent abrasion resistance, heat resistance, corrosion resistance, dimensional stability, biocompatibility, and non-absorption of water, making it a great replacement for metals in many applications.

  • What are the challenges of machining PEEK?

    Machining PEEK can be challenging because it is prone to cracking during processing and requires special experience and knowledge to handle, especially when it comes to stress relief through annealing.

  • Can PEEK be used in medical applications?

    Yes, PEEK is commonly used in medical applications due to its biocompatibility. It is suitable for creating custom medical implants and orthopedic instruments.

  • How does the cost of machining PEEK compare to metals?

    The cost factor for PEEK CNC machining is generally lower compared to certain metals like steel 12L14, making it a cost-effective alternative for many applications.

  • What surface treatments can be applied to PEEK parts?

    PEEK parts often don't require surface treatments due to their inherent chemical resistance. However, options like bead blasting and polishing can be used to improve the surface finish.
