Undercut machining is a crucial technique used to create recessed features, grooves, and complex geometries that cannot be easily machined using standard tools. This process is widely used in PEEK and Delrin machining to achieve intricate part designs.
What is an Undercut?
An undercut refers to a feature that cannot be directly accessed by a standard milling or turning tool. It typically involves a recessed or overhanging section that requires specialized cutting tools or multi-axis machining.
Techniques for Undercut Machining:
- T-slot Cutters: Used for machining T-shaped grooves and slots.
- Lollipop Cutters (Ball-end Mills): Ideal for internal cavities and complex contours.
- Multi-axis CNC Machining: Allows for precise undercuts without repositioning the workpiece.
- Electrical Discharge Machining (EDM): Used for intricate undercuts in hard materials.
- Broaching: A process used for internal undercuts and keyways.
Applications of Undercut Machining:
- Aerospace and automotive components
- Medical implants and prosthetics
- Mold and die-making industry
- High-precision industrial parts

How Undercut Machining Benefits PEEK and Delrin Processing
- Complex Design Execution: Enables machining of intricate geometries required in high-performance applications.
- Improved Component Strength: Allows for custom reinforcement features in structural parts.
- Efficient Manufacturing: Reduces the need for multiple setups and manual post-processing.
- Optimized Surface Finish: Ensures smooth and precise finishes on machined parts.
Conclusion
Both PEEK and Delrin are excellent engineering materials with unique advantages. PEEK offers high strength, chemical resistance, and temperature stability, making it suitable for high-performance applications. Delrin, on the other hand, is cost-effective, easy to machine, and ideal for precision parts that do not require extreme temperature resistance.
Undercut machining plays a vital role in creating complex features in both PEEK and Delrin components. Advanced machining techniques like multi-axis CNC machining, EDM, and specialized cutting tools enable the production of high-precision parts.
