For all kinds of surface processing, we provide a wide variety of steel burnishing media in different materials and peculiar shapes ranging from diagonal to oval to spherical, to be used in rotating horizontal barrels, vibratory tubs, trough or bowl-type finishing machines, and turret-mounted drum machines for polishing or deburing rough surface of molded, cast or forged articles.

Our burnishing media are manufactured in carbon steel, stainless steel 304, 316 and 420 or chrome alloy steel. Normally, carbon steel media are used for common surface polishing with mild chemical compounds. While stainless media are used where there is a corrosive chemical involved, some people prefer chrome alloy steel than carbon steel media for the much better durability.

The media shapes we can supply are:

Eclipses
Spherical steel balls with slight flattening at the poles are recommended wherever exact roundness is not essential, as in many grinding and steel media finishing processes. Spherical steel balls because of their excellent rolling action are most commonly used shape for polishing and grinding media. However, in some polishing applications where the component profile is not flat, the rolling of spheres is interrupted. Hence, steel spheres and eclipses provide similar results. In other applications where high luster is not required, use of eclipses is preferred. The advantage of using steel eclipse balls is its cost-effectiveness i.e., cost of an eclipse is substantially lower than spherical steel balls.

Balcones
Balcones or Satellites (variously called saturn, sputnik, planet, UFO) are mixed with round steel balls and other steel burnishing media (diagonals, pins, eclipses) to achieve overall cleaning, consistent metal polishing and excellent mirror finish all over the component profile.

Round steel balls are most widely used shape in steel media. However, it is not always versatile, as a sphere cannot access corners. It is also unable to make contact in grooves or recesses if the steel ball diameter is larger than the groove width. In such cases, milky areas become apparent on the component surface where balls are unable to provide polishing action. Steel ballcones and satellites works very well in such areas for providing uniform finishing results.

Diagonals / Pins
Steel angle cut cylinders, bevelled diagonals and pins are mixed with steel balls, eclipses, balcones and satellites in the steel polishing media for various mass finishing applications to achieve uniform cleaning, metal finishing and mirror finish all over the component profile.

Spherical steel balls are the most popular and versatile shaped media used in tumblers, barrels, harperizers, centrifugal and vibratory finishing machines. However, a round steel ball cannot access grooves, corners, collars and intricate profiles. To achieve this, a beveled diagonal (cylinder) or pin has to be used. Pins are also appropriate for deflashing holes and finishing intricate jewellery parts.
