Flat Lapping is a technique that is being used since a long time ago. The person who first sharpened a stick by rubbing it with a stone covered with sand was the first one to discover the lapping process. Lapping is a basically a manufacturing process that is a precision engineering process used to provide flatness, parallelism, size and surface finishes to extremely demanding tolerances.
The process is a manufacturing method that removes particles of an abrasive material to remove stock from a surface. It is similar to sanding or grinding technique, except that sanding and grinding use abrasives which are fixed (bonded abrasives) whereas lapping employs abrasives which are suspended in a liquid carrier, and are free to move about. Lapping is sometimes referred to as 'Free Abrasive Machining' as many precision engineering companies are using the same technique with some alternative name.
Lapping can attain a flatness rating of one millionth of an inch (0.000001"), parallelism tolerances of ten millionths of an inch (.00001") and surface finishes to 0.6Ra, using special handling and tooling techniques. We can achieve tolerances at the limits of the lapping process (down to one millionth of an inch) on a case-by-case basis to provide extensive precision engineering services.
Abrading Methods can provide lapping, free abrasive machining, flat honing, fine grinding, polishing, burnishing, precision fine grinding as well as special deburring and cleaning techniques to process your flat surfaces.
