Advantages of Lapping Polishing Machine
Thickness Identity
Lapping allows for much tighter thickness tolerance. Raw materials that have been dry pressed or tape cast, often referred to as “as-fired”, typically have a thickness tolerance of 10%. Standard lap thickness tolerance is +/-.0005”/” and can be as tight as .00005”/” depending on the length, width and thickness of the part or substrate.
Surface Finish
The surface finish of as-fired materials is usually specified in micro-inch max parameters. As a result, the manufacturer can get away with large surface finish variation within batches. Our various abrasives and unique proprietary processes allow for better control over the finish.
Part Uniformity
As we all know, having uniform parts is crucial for producing repeatable results. Precision lapping provides excellent control to ensure uniform pieces within specified parameters.
Flatness
Lapping controls the flatness of your parts or substrates. For information on flatness keep your eyes peeled for our upcoming article on camber, flatness and parallelism or contact us with questions.
Camber Reduction
Precision lapping aids in the removal of deviation, bow and warp on a substrate. Typical substrates in as-fired condition have camber specifications of .002” to .003” inch per inch. Lapping or polishing substrates will decrease camber to .0005”/”.
Parallelism
Achieving parallelism between faces on a substrate can be very important. Lapping is a great way to guarantee parallelism to extremely tight tolerances.
Preparation for Polishing
Precision lapping is used in the preparation of any part or substrate to be polished. The parts go through various lapping abrasives to reduce the subsurface damage before moving on to the precision polishing process.
