Ceramic laps have been known for sharp facets and good polishing
properties...If someone can get one to work. Rather unforgiving,
and relying on critical thin film effects, when operated by the right
person under the right conditions, most agree they produce perfect
finishes.
The rest of us would like these results with a more forgiving version
of the lap, that being a wider band of operating parameters.
The "MATRIX™" Ceramic Composite lap has a self-renewing microtexture
and surface complexity that allows better polish retention and a less
critical fluid film thickness. The MATRIX™ surface was characterized
by computer programs similar to those used in the design of all-weather
tires.(FD is 1.8927).
The 8" MATRIX™ is made on a full-thickness master lap baseplate to
emulate the heavy rigid feel of a ceramic lap. The MATRIX™concept was
suggested by Adamas Instrument, as was the suggestion of the thicker
base.
The 8" MATRIX™ price is $135.00.
Does it WORK?
