new Technology has enabled us to eliminate the problems associated with conventional lapping
lapping has always consisted of rubbing the work piece to be finished on a flat plate using a loose abrasive and oil mixture between the plate and the workpiece.
As the plate wears with repeated use the contour of its surface must be constantly maintained through the lapping operation to maintain the plates accuracy. Maintaining the accuracy of these plates can only be achieved by pain staking, tedious and lengthy sequences to correct the wear with the use of several lapping plates anong with experienced personel.
A lapping device is only useful as long as it retains it contour to a very precise degree. When lapping with loose abrasives you are lapping the high and low areas at the same time. (Figure 1) Galling and /or scratching of the articles being lapped is a common occurrence.
The use of loose abrasives is not needed with our lapping plates. We offer a full line of lapping plates with the diamonds permantly inpregnated into the surface and retained by an extremely hard wear-resistant matrix. Uhl Technologies' diamond lapping plates lap only the higher areas down to the lower areas, (Figure 2) Galling and/or scratching are virtually non-existant due to the diamond being permanently fixed into the surface, therefor decreasing your lappping time by 50%.
Cleaning of our lapping plates is very easy. Lapped off debris is simply cleaned from the plate by adding a few drops of our lapping fluid and wiping with our industrial-lint free paper wipes.

Uhl Technologies offers five standard mesh sizes to be impregnated into the surface of your lapping plate. Shown in the table to the left are the five sizes available as well as the micron size of diamond and the micro inch finish you can expect to receive.
