  • What Is Spherical Lapping And Polishing

    What is Spherical Lapping The term lapping is used to describe a number of various surface finishing operations where loose abrasive powders are used as the grinding agent at normally low speeds. It is a process reserved for products that demand very tight tolerances of flatness, parallelism, thickness or finish.What is Spherical Lapping The term lapping is used to describe a number of various surface finishing operations where loose abrasive powders are used as the grinding agent at normally low speeds.
