Common Grades and Applications of Machined PEEK
We machine a full spectrum of PEEK grades to match different performance requirements and regulatory standards.
| PEEK Grade | Key Properties | Typical Applications |
| Unfilled PEEK | Good wear resistance, chemical resistance, high temperature stability | General industrial components, pump parts, valve seats |
| Glass-Filled PEEK | Higher stiffness, dimensional stability, reduced creep | Aerospace brackets, electrical housings, structural parts |
| Carbon-Filled PEEK | High strength, improved thermal conductivity, low friction | High-performance bushings, seals, wear rings |
| Medical-Grade PEEK | Biocompatible, sterilizable, traceable | Surgical instrument handles, implantable device prototypes, diagnostic equipment parts |
By pairing each grade’s inherent strengths with precision machining, Beska produces PEEK components that perform reliably in real-world conditions, ranging from the operating room to the engine compartment.
Surface Finishing Options
To enhance the performance, durability, and aesthetics of PEEK parts, Beska offers a range of secondary surface treatments tailored to your project needs:
- Deburring—remove sharp edges and residual burrs for safer handling and smoother assembly.
- Polishing—achieve low-friction, visually smooth surfaces ideal for medical, aerospace, and precision industrial components.
- Custom coatings—apply specialized coatings to improve wear resistance, reduce friction, or enhance chemical compatibility.
- Coloring options—for functional coding, part identification, or aesthetic purposes.
These finishing options allow Beska to deliver ready-to-use, high-quality PEEK components that require minimal post-processing and perform reliably in demanding environments.
Why Choose PEEK for CNC Machining?
PEEK offers a rare combination of plastic versatility and metal-like strength, making it one of the most capable materials for precision CNC machining.
High mechanical strength and stiffness: PEEK maintains exceptional stability and load-bearing capacity even under continuous mechanical stress.
Thermal stability up to 250°C: It resists deformation and retains dimensional accuracy at elevated operating temperatures.
Excellent chemical resistance: PEEK withstands aggressive fluids and solvents, making it reliable in harsh industrial environments.
Low moisture absorption: It absorbs minimal moisture, ensuring parts stay precise and stable even in humid conditions.
Our PEEK CNC parts are engineered to maintain stability under thermal, chemical, and mechanical stress, giving engineers predictable performance in challenging environments.

CNC Machining Capabilities for PEEK
At Beska, we combine precision equipment, experienced machinists, and rigorous process control to handle even the most complex PEEK projects.
Advanced Multi-Axis Machining
We utilize 3/4/5-axis CNC milling and turning to handle intricate geometries, cylindrical components, and parts requiring multiple operations in a single setup.
Precision and Complex Features
Our PEEK parts routinely achieve tolerances of ±0.02 mm, including thin-wall sections, tight radii, and other complex surface features that demand careful process control.
Secondary Finishing and Production Flexibility
To enhance part performance and aesthetics, we provide deburring, polishing, and custom coatings. From rapid prototyping to full-scale production, Beska ensures a smooth workflow from CAD model to finished component.
Material & Design Guidance
At Beska, we also provide engineering support from the very beginning. Our team works closely with your designers and engineers to ensure manufacturability, performance, and compliance. We help you:
- Recommend minimum wall thickness and critical dimensional tolerances to prevent warping or deformation during machining.
- Identify geometries prone to stress, creep, or thermal distortion and suggest design adjustments to maintain stability.
- Select the appropriate PEEK grade based on mechanical load, chemical exposure, thermal requirements, and regulatory standards.
- Optimize part orientation, fixturing, and machining strategy to achieve complex features in a single setup, saving time and reducing risk.
By collaborating early, our engineers help reduce trial-and-error iterations, lower production costs, and ensure your PEEK components meet both functional and regulatory requirements from prototype to full production.

FAQ
PEEK and Delrin (acetal) each have strengths depending on the application. PEEK offers higher temperature resistance, superior chemical resistance, and better wear than Delrin, making it ideal for aerospace, medical, and high-performance industrial parts.
We can machine thin-wall PEEK parts down to 1 mm, depending on geometry and support features.
Aerospace, medical, automotive, electronics, and industrial equipment, especially for high-temperature, chemical-resistant, and precision components.
PEEK is more expensive than common plastics, can be challenging to machine thin or intricate parts, and may require specialized tooling for complex geometries.
