When precision is key, internal polishing plays a vital role in refining the surface finish of metal components in San Bernardino, CA. At Extrude Hone AFM, we specialize in abrasive flow machining (AFM) technology, a cutting-edge method that removes surface imperfections and leaves components with a uniform, smooth finish. Whether you operate in aerospace, medical manufacturing, or automotive sectors, our internal polishing services can dramatically improve the performance and longevity of your parts.
What Is Internal Polishing?
Internal polishing is the process of smoothing and refining the interior surfaces of metal components. It addresses imperfections left behind during the initial manufacturing stages, such as burrs, rough edges, or recast layers. These surface defects can lead to performance issues like friction, fluid inefficiency, or even stress fractures in the material.
At Extrude Hone AFM, we use abrasive flow machining to deliver high-precision internal polishing for metal components of all shapes and sizes. This process ensures consistent and predictable results, no matter how intricate the internal geometries may be.
How Internal Polishing in San Bernardino, CA Works
The internal polishing process begins with careful setup and customization to match your project’s specific needs:
- Tool Setup: We secure the part and direct the abrasive flow toward the internal passages requiring polishing.
- Abrasive Selection: Depending on the level of refinement required, we choose the right abrasive grit, from coarse particles to fine powders.
- Media Composition: We combine the abrasive grit with a specially formulated media, adjusting viscosity and concentration for optimal material removal.
- Hydraulic Pressure: Using hydraulic rams, we pressurize the media and force it through the internal passageways, effectively polishing the internal surfaces through controlled erosion.
This highly customizable process allows us to deliver uniform results that meet even the most demanding specifications. Our expertise in internal polishing extends to various metals, including titanium, aluminum, stainless steel, and copper alloys.
