Lapping Services

Our lapping procedure is a unique process for removing material by the action of abrasive media suspended in our proprietary suspension agent, that is suspended between a rotating wheel and the workpiece.

As the wheel rotates it carries the loose abrasive across the face of the work. Media, lap size, machine speed rate and loading pressure carry combinations that determine the efficiency of the process and quality of the finished part. Lapping offers extreme accuracy and is a cost competitive process in either high or low volume workpiece requirements. This process can be used before the finished step or as the finish step. Whenever size, flatness, parallel or finish is a problem, lapping is the answer.

We work on parts .015 inch diameter through 18-inch diameter and as thin as .020 inch with a flatness of .000005 inch and parallelism of less than .0005 inch. We can produce finishes of two light bands through the selection of proper abrasive, pressure and lapping cycle times.

A water based slurry is used, not oil based.

WHAT DOES RMS MEAN?

As described in ASME B46.1, RMS is the root mean square average of the profile height deviations from the mean line, recorded within the evaluation length. Reveal the RMS formula for more insight.

Calculating RMS

L = evaluation length

Z(x) = the profile height function

The digital approximation is:
