We maintain a separate plant to modify our precision balls. We grind flats on balls. We drill holes in balls. We thread balls. We make balls with stems, shafts, and handles. This is a fully integrated CNC facility with machining centers, turning centers, EDM die sinkers, fast hole drilling machines and wire EDM machines. Our grinding capabilities include surface grinding, internal and external cylindrical grinding and centerless grinding.

Modified Balls of almost any configuration are manufactured in our Los Angeles facility. Our facility includes complete E. D. M. (Electrical Discharge Machining), conventional machining and grinding capabilities. Balls with flats, holes, threads, or with stems brazed, welded, glued, screwed or riveted can be produced. A fairly common modification of a ball is to have a stripe of the diameter of the sphere ground cylindrical. This is often done to provide clearance on ball plug gages. |
A wire EDM machine can be used to produce almost any contour on a ball.
Pricing available per your print, drawing or description.
Using Electrical Discharge Machining, EDM, Bal-tec can drill or otherwise modify precision balls made of hardened steel or tungsten carbide. E.D.M.ing causes very little or no change in the original quality of the precision ball.
This computer controlled equipment uses millions of tiny bursts of electrical energy to erode away selected areas of a precision ball to form almost any configuration required. Typical shapes include round holes, counter bores, conical lands, square holes, slots, and keyways.
The very simple tooling required make E.D.M.ing well suited for prototype and small quantity production.
Attaching a stem or handle to a precision ball is easily accomplished by E.D.M.ing a hole part way through the ball and gluing the handle or stem in place. Handles attached by this method resist shock and will take a strong pull. This technique eliminates the distortion and size change associated with brazing or soft soldering.
