Understanding the peek cnc machining price is critical for industries that rely on high-performance polymer components with exceptional strength, heat resistance, and dimensional stability. PEEK (polyether ether ketone) is one of the most advanced engineering plastics used today, and machining it requires specialized tools, high heat-tolerance techniques, and precision cutting strategies. In this article, we explain what determines PEEK machining cost, available material grades, key industries, and common accessories used in PEEK components.
What Determines PEEK CNC Machining Price?
PEEK is significantly harder and more heat-resistant than standard plastics, which increases machining difficulty. The peek cnc machining price depends on multiple engineering factors that influence tool wear, cycle time, and machining quality.
1. PEEK Material Grade
Different grades influence cost due to mechanical strength, additives, and performance.
Virgin PEEK
- Pure PEEK polymer
- High strength and stability
- Excellent for medical and aerospace use
Glass-Filled PEEK (GF30)
- Reinforced with glass fiber
- Higher stiffness
- Used for load-bearing components
Carbon-Filled PEEK (CF30)
- Superior strength, lower friction
- Excellent for wear-resistant applications
These grades influence tool wear and directly affect peek cnc machining price.
2. Part Complexity & Tolerances
PEEK parts with:
- Thin walls
- Multiple undercuts
- Tight tolerances (±0.01–0.02 mm)
require specialized cnc machining peek services, increasing the final price.
3. Heat Management During Machining
PEEK softens at high temperatures. Machining requires:
- Coolant strategies
- Slow feed rates
- Specialized carbide tooling
These factors add to machining time and cost.
4. Surface Finishing Requirements
Common finishes that affect peek cnc machining price include:
- Polishing
- Deburring
- Precision grinding
- Dimensional inspection
5. Production Volume
Prototype orders cost more per piece, while wholesale peek cnc machining significantly reduces unit cost.
