Why PEEK Machining is Special
PEEK is different from other plastics. With a high melting point and low thermal conductivity, machining PEEK generates heat at the tool’s cutting edge. This can cause surface cracks, tool wear and part deformation. Reinforced grades, such as glass reinforced PEEK, carbon fiber-filled PEEK or other PEEK reinforced variants, require careful process control due to their abrasive nature.
At MetalQuest we manage these challenges with:
-
Optimized feeds and high tool infeeds for stability
-
Advanced cutting tools, including coated inserts and diamond tooling when required
-
Precision workholding to reduce vibration and ensure high dimensional stability, combined with accuracy
-
High-pressure coolant and chip evacuation to dissipate heat effectively
Our PEEK Machining Capabilities
- CNC turning, milling, Swiss, and multi-spindle machining for complex geometries
- Milling and turning of PEEK parts from rods, sheets and blanks
- Tight tolerances validated through CMM inspection, including high-precision features down to ±0.0005 in. when the application allows.
- Surface finishing options to enhance mechanical properties and functionality
- Scalability from small prototype batches to industrial-grade PEEK plastic high volume production
We deliver durability, accuracy and repeatability on every project.

Industries We Serve
Medical
PEEK is used in medical grade PEEK applications such as implants, dental components and surgical tools. Its excellent mechanical properties, resistance to various sterilization methods and long term dimensional stability make it reliable inside the human body.
Defense
For defense projects, industrial grade PEEK provides high temperature resistance, abrasion resistance and chemical resistance. Components made from custom PEEK machined parts are lightweight, durable and mission ready.
Industrial
From pumps and valves to the automotive industry, PEEK performs in extreme environments with excellent wear and heat resistance. Its abrasion resistant thermoplastic nature ensures longevity in equipment exposed to elevated temperatures and harsh environments.
Quality and Reliability
Every PEEK machining project is backed by:
- ISO 9001–certified quality management supporting all machining and inspection processes
- In process monitoring to eliminate defects
- Validation of PEEK components using coordinate measuring machines (CMM)
- Consistency across production, from single prototypes to high volume runs
We know PEEK is a high performance material for mission critical applications, so every shipment is inspected and verified before delivery.
