Lapping compounds can be purchased, but be sure of grit size
. Never use a grit that is too coarse as it can score the metal.
a) Small Grit b) Large Grit; Blasting pressure a) 4 bar b) 5 bar; Blasting time a) 10 sec b) 20 sec.
With the given matrix formula and diamond grade, the grit size
, grit concentration, number of water gaps at the crown, and bit wall thickness are the main bit performance parameters which can affect the wear conditions of the tools.
Decrease grit size
in small increments (don't go from 220 to 600).
The characteristic of a grinding wheel depends upon the combined elements of abrasive grains, grit size
, bond, grade and structure.
The roughness data (mean Ra and Rz values) are shown in Table 2; the grit size
of diamond discs affected both the Ra (p < 0.001) and Rz parameters (p < 0.001).
The grit size
is carefully controlled in the stone's manufacture and the steel to which the diamond is affixed is truly flat.
The studies [21, 22] indicate the strong influence of grit size
of abrasive fracture.
The starting paper grit size
will depend on the magnitude of damage created during sectioning (1) and the amount of material that needs to be removed in order to reach the target area for inspection.
There are numerous particle sizes of AO (called grit size
) that impact the depth of the peaks and valleys produced by blasting.
