Process: The Step-by-Step of PAEEK CNC Machining

Our PAEEK CNC Machining process is optimized to handle PAEEK’s unique properties—including its high melting point and rigidity—ensuring efficiency, quality, and consistency at every stage.

Design & Programming: Our engineers convert your 3D models into CNC code, selecting optimal cutting techniques and tool selection (e.g., diamond-coated carbide tools for PAEEK’s abrasiveness) to minimize tool wear and maximize precision.

Machine Setup: We calibrate CNC mills, lathes, and drills to match your part’s specs—adjusting spindle speeds (2,000–12,000 RPM) and feed rates (30–600 mm/min) to avoid overheating PAEEK.

Material Loading: We use high-quality PAEEK resin (or reinforced grades like glass-filled PAEEK) cut into precise blocks to reduce waste and ensure uniform part density.

Machining Operations: We perform CNC milling (for complex shapes), CNC turning (for cylindrical parts), and drilling operations (for holes as small as 0.4mm) with real-time torque and temperature monitoring to prevent tool breakage.

Grinding Processes: For parts needing ultra-smooth surfaces, we use precision grinding to achieve Ra values as low as 0.1μm—critical for medical or optical applications.

Inspection: Every part undergoes dimensional checks using digital calipers, optical comparators, and CMMs to verify tolerance standards—we discard any parts that fall outside your required range.

FAQ

Can recycled PAEEK be used for critical applications like medical devices or aerospace parts?

While recycled PAEEK retains 85% of the strength of virgin PAEEK and works well for non-critical parts (e.g., industrial tooling), it is not recommended for critical applications like medical devices or aerospace components. These sectors require strict consistency in material properties (e.g., biocompatibility, low outgassing) that virgin or specialty PAEEK grades (e.g., ISO 10993-certified for medical use) are engineered to meet. For critical projects, we only use virgin PAEEK from certified suppliers to ensure compliance with industry standards like ISO 13485 (medical) or AS9100 (aerospace).

How does the cost of PAEEK CNC Machining compare to other high-performance plastic machining (e.g., PEEK, PAS)?

PAEEK is slightly more costly than PEEK or PAS due to its superior thermal stability and strength, but the long-term value often offsets the upfront expense. On average, PAEEK CNC Machining costs 10–15% more than PEEK machining and 20–25% more than PAS machining for equivalent parts. However, PAEEK parts have a longer service life (up to 50% longer in high-temperature environments) and require less maintenance, reducing total ownership costs. Additionally, our cost-effective production processes—such as optimizing material usage and streamlining machining steps—help lower prices by 25–30% compared to competitors.

Do you provide certification documents for PAEEK machined parts, and what types of certifications are available?

Yes—we provide comprehensive certification documents tailored to your industry’s requirements. For aerospace parts, we offer AS9100 compliance certificates, material traceability reports (linking parts to original PAEEK resin batches from suppliers like Victrex), and FAR 25.853 flame test reports (for flame-retardant PAEEK parts). For medical devices, we include ISO 13485 certificates, biocompatibility test results (ISO 10993), and sterilization validation reports (for autoclave or gamma radiation). For industrial or consumer parts, we provide ISO 9001 quality certificates and dimensional inspection reports (with CMM data).
