Description

Ballizing with Tungsten Carbide Balls Low-cost, high-speed hole sizing and finishing Ballizing or ball burnishing is a fast low-cost process to sizing and finishing tubing and holes in metal.  Pressing a slightly oversize tungsten carbide ball through the unfinished hole brings the hole up to desired size in seconds.  The resulting surface finish is excellent and both size and finish results are very consistent.  Industrial Tectonics can provide application assistance.

Tungsten carbide balls are used where extreme hardness and wear resistance is required; in such applications as bearings, ball screws, valves, flowmeters.  TC balls are also used for coining and pivots, detents and tips for gages and tracers.  Decimal-inch size tungsten carbide balls are widely used for ballizing or hole sizing.  TC balls are also used for gauging and checking.
