Frequently Asked Questions

How do you prevent dimensional "washout" on tight-tolerance features?

We use precision-controlled mechanical laps and custom masking to ensure that polishing removes only microns of material, preserving the geometric integrity of your critical mating surfaces and sharp corners.

What is the lowest Ra value your polishing service can consistently achieve?

Our multi-stage process can reach a surface roughness as low as 0.02 µm Ra, which is essential for reducing friction in high-speed rotating motor components or gimbal assemblies.

Can you ensure surface uniformity across complex, non-planar geometries?

By utilizing five-axis centrifugal finishing and specialized media, we provide a uniform polishing finish across complex drone frames and curved aerodynamic fairings that manual methods cannot match.

How does your polishing process affect the fatigue life of aluminum parts?

Our process is designed to eliminate microscopic "notches" or stress risers created during CNC machining, which significantly delays crack initiation and extends the operational lifespan of high-stress structural components.

Do you offer different levels of reflectivity for optical sensor housings?

Yes, we provide calibrated finishes ranging from satin (diffuse) to high-mirror (specular) to meet your specific requirements for thermal emissivity and light management for onboard sensors.

Will the heat generated during polishing cause material warping?

We use liquid-cooled wet polishing techniques to manage thermal energy, ensuring that thin-walled drone components remain dimensionally stable and free from heat-induced distortion.
