Hi All I've been looking at lapping machines, like this, <http://pimg.tradeindia.com/00308895/b/0/Lapping-Machine.jpg>
and wondered if anyone knew more about the theory of the grooves. While I understand how there is constant velocity on the conditioning ring periphery, if the plate is grooved then surely there will be more wear on the inside? The picture that I drew up, below, exaggerates the effect, but the principle remains. The load area in the centre of the plate is much smaller. http://www.fotothing.com/photos/37e/37e8a4e3e10d84bbc8e987788f150cb3.jpg I've read up some, and the grooves are never mentioned as affecting the process in terms of the loading, but if one was to use a smooth plate, or a grooved plate(radial), how can the grooves not affect the plate loading? Also, nothing is negligible when these machines lap to nanometre resolution.
