FAQ - Microball answers all your questions:

Polishing balls in different processes

Polishing balls are used in various surface finishing processes
depending on the desired result and material properties. In mass
finishing, they ensure even smoothing through continuous relative
movement between workpiece and ball. In ball polishing, they create a
fine, glossy surface through targeted friction. In high-gloss densification,
polishing balls apply high energy to the workpiece surface to achieve
a particularly dense, mirror-smooth structure. In each process,
they significantly contribute to improving surface quality.

Where are polishing balls used?

Polishing balls are used in surface finishing, especially for mass
finishing, polishing, cleaning, or densifying workpieces. They are
employed in tumbling or vibration machines to smooth, refine, or
remove residues from metal, plastic, or ceramic surfaces — for example,
in jewelry manufacturing, medical technology, aerospace, or
toolmaking. Depending on the process and material, polishing balls
ensure uniform, glossy, and burr-free results.

How long do polishing balls last?

The lifespan of polishing balls strongly depends on the material used,
the processing method, and the stress in the respective process.
Stainless steel balls are particularly durable and can be used for many
years with regular cleaning and proper application. Ceramic balls are
characterized by even higher wear resistance and therefore offer an
especially long service life, even under intensive use. Early replacement
is usually only necessary in case of mechanical damage or significant
material loss.

Shine and Smoothness for Metallic Surfaces

Polishing balls are used in numerous industrial processes where smooth,
shiny, and precise surfaces are required. They play a central role in vibratory
finishing, ball polishing, and high-gloss densification. In these processes,
the balls mechanically work on the surface of workpieces, reducing
roughness, rounding edges, and bringing surfaces to a high gloss.

The polishing balls available from microball typically consist of stainless
steel or ceramic. Both materials impress with their hardness, dimensional
stability, and durability — properties essential for long-term use in abrasive
processes. Depending on the requirement, various ball diameters are
available to achieve optimal results with different workpiece shapes and
materials.

Thanks to their high resistance, polishing balls can be reused multiple
times over long periods without losing effectiveness. microball GmbH
offers a wide range of high-quality polishing balls and is happy to assist
you in selecting the right ball type for your application.
