???? Ballizing

Ballizing is a method of finishing on internal diameter. It can give improvement in dimensional tolerance, roundness and surface finish.

Press a high precision ??? ???? ? through an undersized hole in metal, to eliminate tool marks and to obtain dimensional accuracy. As the ball passes through the hole it does not remove material, but compresses it to form a much improved work hardened surface and a large improvement in hole tolerance.

Ballizing with ??? ???? ?

Ballizing is a fast low-cost process to sizing and finishing tubing and holes in metal. Pressing a slightly oversized ??? ???? ? 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.

??

??? ???? ? are used in applications requiring extreme hardness and resistance to wear and abrasion; and are able to withstand hard shocks and impacts. Our balls are made with 6% nickel binder or 9% nickel binder. Common applications for ??? ???? ? include ball valves, flow meters, ball bearings, linear bearings, and ball screws. ??? ???? ? can also be used for coining and minting; as pivots, detents, and points or tips for gauges, tracers and comparators; and as metal balls for ballizing, hole sizing, gauging, and checking.

??

??? ???? ? are ideal for applications where extreme hardness must be accompanied by high resistance to wear and impact. They are well-suited to elevated temperatures, corrosion, humidity, abrasion, and poor lubrication conditions.
