We drill and tap balls, including balls with holes through them, balls with blind holes, balls used for jewelry, protective ends, decoration, and contact elements.

We manufacture gages, including weight standards, ball gages, go/no-go gages, and spherical masters.

We also manufacture precision valve balls. Our valve balls have superior surface finishes and roundness characteristics.

Additionally, we provide spherical grinding and lapping services. We lap balls, partial spheres, and spherical seats. We have the equipment to perform online leak tests and inspect the roundness and surface finish of spherical surfaces. Our ball manufacturing capabilities allow us to construct gaging as required to meet specific needs and circumstances.

We will custom manufacture precision metal and plastic ball products to meet your needs. Our great flexibility allows us to be competitive in small prototype runs as well as large production runs. We provide engineering services, and we can aid in the design of your products.
