As part of our services, we not only 3D print Peek, but also offer advanced CNC machining for this extraordinary material. Peek, or polyetheretherketone, emerges as a high-end choice, characterised by exceptional performance. Its processing by CNC milling and turning opens up new possibilities, allowing this semi-crystalline thermoplastic to be moulded to specific requirements.


Tight tolerances: CNC machining of Peek represents a breakthrough in achieving extremely tight tolerances. This is crucial in industrial applications that require absolute precision. Peek's ability to maintain these tolerances during the CNC milling process ensures the dimensional consistency required for the most critical applications. The resulting precision allows components with complex geometries to be manufactured, satisfying the demands of advanced designs and demanding engineering challenges.

High Temperature Resistance: Peek's remarkable resistance to high temperatures is a distinctive feature that makes it particularly suitable for extreme operating environments. CNC machining, rather than compromising these thermal properties, preserves and enhances them. This means that Peek parts, even after CNC milling, can easily withstand high thermal conditions while maintaining their stability and structural integrity. This consistent resistance to high temperatures greatly expands Peek's applications in industries such as aerospace, where extreme conditions are the order of the day.

High Mechanical Strength: CNC machining of Peek represents a stage of refinement of its already exceptional mechanical strength properties. The precision milling helps optimise the molecular arrangement of the material, further improving its strength. CNC-machined Peek is thus a material that not only retains its original strength but strengthens it, offering durability and reliability in demanding industrial environments.

Flame-retardant UL94 V0: Retaining the UL94 V0 flame-retardant rating even after CNC machining confirms Peek as a safe choice in fire-risk environments. Its ability to self-extinguish contributes significantly to safety and compliance with the highest fire standards, confirming its crucial role in applications requiring fire-resistant materials.

Food Contact Certificate: Peek's food contact certification perseveres uncompromised even after CNC machining. This is crucial in sectors such as the food industry, where safety and compliance with food regulations are priorities. Peek's ability to maintain its suitability for food contact helps ensure safe and reliable applications in contexts where hygiene is paramount.


Visible Tool Marks: Although the CNC machining of Peek offers exceptional precision, it is important to consider the possibility of visible tool marks on the surface of the material. This aspect, if not handled properly, could be an aesthetic drawback. However, it is reassuring to know that with the use of advanced machining techniques and the expertise of skilled operators, this visibility can be minimised or even eliminated. Attention to detail during machining can lead to visually impeccable results, ensuring that the surface of the CNC-machined Peek retains its aesthetic integrity.

Limited Geometric Freedom: CNC machining, while offering extraordinary precision, can present certain limitations in the geometric freedom of the shapes that can be produced. This is particularly relevant in applications requiring complex geometries or special design details. However, it should be noted that with careful analysis and the use of advanced machining strategies, it is often possible to overcome these limitations. Expert advice in the design and machining phase can help maximise flexibility in creating complex shapes while maintaining the required precision.

High Material Cost: One aspect to consider when choosing CNC-machined Peek is its high cost. Despite the superior performance offered by the material, budget consideration is crucial, especially in projects with limited financial resources. A careful cost analysis, balanced with project-specific performance requirements, is essential to ensure a considered and sustainable choice.

Maximum Size Limitations: CNC machining of Peek may result in limitations in the maximum size of parts that can be produced. This size constraint must be carefully considered in applications requiring large components. In such contexts, it may be necessary to explore alternatives or assembly strategies to meet the desired dimensions. Careful planning and collaboration with CNC machining experts can help optimise the process and find effective solutions for the limited maximum Peek dimensions.

Applications of Peek CNC

CNC machining of Peek, with its outstanding characteristics, lends itself to a wide range of applications in diverse industries. In the food industry, where hygiene regulations are strict, CNC-machined Peek is used for the production of components that come into direct contact with food, ensuring safety and compliance with industry standards. The aerospace industry benefits from Peek's properties in the manufacture of structural parts, thanks to its combination of mechanical strength, light weight and ability to maintain integrity at extreme temperatures, thus contributing to the efficiency and durability of aircraft.

In the automotive sector, CNC-machined Peek presents itself as a viable alternative to metal, providing components with superior tensile strength, heat resistance and significant weight reduction. This versatility also extends to the medical field, where CNC machining of Peek is used in the production of customised medical devices, exploiting its hygienic, strength and precision characteristics.

The chemical and nuclear industries find Peek an answer to their needs for chemical and thermal resistance. Its ability to maintain structural integrity in corrosive environments and high temperatures makes it essential for the production of critical equipment and components in these applications.

In addition, Peek's CNC machining offers a unique opportunity for rapid prototyping and the production of customised components. The flexibility of this process allows the material to be adapted to the specific needs of particular projects, further expanding its application possibilities in a wide range of industries.


Our Peek CNC machining services stand as the meeting point between innovation and the most advanced industrial requirements. Despite the challenges that can arise, such as visible tool marks and limits in geometric freedom, CNC-machined Peek maintains its leading position in the most demanding industrial applications.

The precision guaranteed by the extremely tight tolerances is crucial for projects requiring dimensional consistency in every detail. Resistance to high temperatures remains unaffected, allowing Peek to be used in extreme operating environments, from aerospace manufacturing to the most severe industrial applications.
