For decades, RAM has specialized in machining some of the world’s most advanced engineering plastics and metals for demanding industries such as aerospace, medical, defense, and industrial manufacturing. We help customers solve complex manufacturing challenges that many machine shops cannot handle. When it comes to machining PEEK parts, precision, expertise, and process control are essential.
Key Factors for Machining PEEK Parts
PEEK (polyether ether ketone) is widely valued for its exceptional strength, chemical resistance, thermal stability, and wear performance, making it one of the most sought-after engineering plastics in modern manufacturing. While PEEK delivers impressive performance advantages, achieving optimal results requires a disciplined machining approach. To consistently produce high-quality machined PEEK parts, manufacturers should follow several key machining best practices that help maximize accuracy, performance, and overall part quality:
- Use Sharp, High-Quality Cutting Tools: PEEK machines differently than many standard plastics. Sharp carbide tooling helps reduce cutting forces, minimizes material deformation, and produces cleaner edges. Well-maintained tools also reduce burr formation. This improves surface consistency throughout production runs.
- Control Heat During Machining: Although PEEK performs exceptionally well in high-temperature environments, excessive heat generated during machining can affect dimensional stability. Skilled machinists carefully manage cutting speeds, feed rates, and tool engagement. This minimizes thermal buildup and preserves part accuracy.
- Optimize Workholding Techniques: Improper clamping pressure can introduce distortion into precision components. Experienced machinists use specialized fixturing methods that securely hold the material. This prevents stress that could impact final dimensions.
- Account for Material Characteristics: PEEK offers excellent dimensional stability compared to many engineering plastics, but machining PEEK parts still requires understanding how the material responds during cutting operations. Careful process planning helps maintain tight tolerances on complex geometries and critical features.
- Focus on Surface Finish Requirements: Many aerospace, medical, and semiconductor applications require exceptionally smooth surfaces. Optimized tool paths, proper tooling selection, and secondary finishing processes can help achieve the clean, professional appearance and performance characteristics customers expect.
- Partner with Experienced Plastic Machining Specialists: Successfully machining PEEK parts requires more than modern equipment. It demands years of hands-on experience, material expertise, and a deep understanding of how engineering plastics behave under different manufacturing conditions.
