Carbon Steel Tumbling Media

www.KramerThinksGreen.com logo

Steel shot is a polishing and burnishing media that produces a bright shine. It is available in a variety of shapes and sizes. Its substantial weight, with a density of approximately 320 pounds per cubic foot (three times the density of ceramic media), exerts added pressure to a mass of components and is especially effective in reducing finishing times.

Advantages of Carbon Steel Tumbling Media

As steel media impinges on a part, its surface is work-hardened. The working action imparts compressive stress as a beneficial byproduct of the finishing process. In many instances, the process can replace steel shot blasting as a work-hardening step. Parts processed with steel media have longer cycle lives and greater resistance to wear as a result of this compressive stress action. Most steel shot does not remove metal from parts, though our Abcut™ shape is designed for metal removal.

Steel shot is a non-consumable media, so wastewater treatment is limited to removal of the soils from your parts only, because steel does not create or absorb soils from wear, as do other media. Steel Media is considered a capitalized investment instead of a consumable expense.

Plating Preparation

Parts that appear smooth are actually characterized by micro-imperfections, which cause plating problems. The weight of steel media flattens these minute irregularities and prepares a surface for more satisfactory plating. This action is especially critical during the deposition of nickel or other solutions that typically do not fill the depressions, but follow the higher contours of the metal.

When plated parts are finished with steel media, a compacting action rolls down and spreads the surface of the softer plate to fill any "pin-point" holes. This process helps eliminate porosity and increases the corrosion resistance created by the plating process.

This design combines the burnishing abilities of balls and cones into one scientifically proportioned shape. Good burnishing action with the ability to reach corners and recesses. Tapering to pointed ends, pins reach into recesses and grooves, deflash through-holes and clean threaded areas. Strictly for reaching recesses. Must be mixed with other shapes to produce good results.

Round balls with slight flattening at pole ends. Precise roundness is not required for the majority of steel media finishing applications. Thus, two small flat spots at opposite poles are not objectionable. Pole-flattened balls are less expensive to manufacture and customers benefit from these economies through lower prices. This shape introduces an oscillating motion to the finishing mass and provides more surface-to-surface contact than balls.
