Precision Tungsten Carbide Hole Polishing – Ra0.015 Finish
Learn about high-precision polishing of tungsten-carbide parts to a mirror-smooth Ra 0.015 finish — ideal for holes, dies, and tooling where burr-free surfaces are critical. Ensure durability and performance with expert polishing techniques.
Tungsten carbide, used as a material for dies or mechanical parts, has excellent wear resistance and high-temperature resistance. In many cases, the parts or holes used require a mirror-like surface finish. We specialize in delivering carbide part polishing with a precision of Ra0.015, ensuring top-tier quality and performance.
Understanding Carbide and Its Polishing Needs
Carbide’s impressive hardness, typically between 85HRA to 95HRA, makes it a challenging material to work with, particularly during the finishing stages. The machining process often creates burrs that can affect the functionality and aesthetic of the part. Removing these burrs, or polishing, is therefore a critical step in the production of carbide parts.

Techniques for Achieving Ra0.015 Smoothness
Different smoothing techniques are employed based on the required finish:
- For basic smoothing needs, oilstones are utilized to grind away imperfections.
- Higher precision requirements, such as those needed for carbide parts demanding a smoothness of Ra0.015, necessitate the use of diamond paste for polishing. This method ensures an ultra-fine finish, crucial for high-performance parts.

The Importance of Expert Polishing Techniques
Handling the polishing of tungsten carbide parts, including intricate hole polishing, requires not only the right materials but also skilled technicians. Our team comprises experienced professionals adept at managing the delicate balance of achieving the desired smoothness without compromising the part’s dimensional tolerances.
