Grinding Services

Lapping is the process of mixing loose abrasives with vehicle such as oil and letting it remove material from the work piece at very controlled rate. We use the "Free Abrasive " method of lapping which simply means we use a hardened table as opposed to a soft cast iron table. We can remove stock faster and still give you all the benefits of conventional lapping.
