Surface Plate Calibration and Lapping

Surface Plate Calibration and Lapping

Here’s an interesting video for all you “max flat” lapping freaks. Surface Plates are Calibrated and then lapped in a few minutes. OxToolCo, (Surface Plate Calibration and Conditioning).

They,(Precision Granite) are using lose Diamond grit, (60um) granted, they are removing small amounts but they lap a 3X4 foot Granite plate in minutes. Very interesting process to watch.

I will have to try some lose diamond for lapping.

What was also interesting was their discussion on surface deflection due to temperature change. It would be interesting to measure the effect of hydration on a synthetic stone.

This guy, Tom Lipton, OX Tool Co, has some very interesting videos.
