To put it
out in a generalized way, diamond tools, which integrate coarse diamond
grit, usually features high
processing efficiency. However, these
diamond tools are exposed to the risk of roughness. Unlike it, diamond tools
utilizing fine diamond grit is impervious to any such risk. In order to ensure
that requirements of roughness are duly met, a coarser grit would deem fit the
need for enhanced processing efficiency. Also, it is the case that the hold
capacity to the diamond varies from one bond of diamond dressing tool
to another. Moreover, there exists certain consideration, which cannot be
overlooked while making a choice of diamond grit.
Nature of Work-piece
- In case the work piece carries high hardness, a choice of coarser grit diamonds should be made. This will ensure the less amount of heat generated in the process of cutting or grinding.
- In case the work piece has adequate stability, coarser grit lessens the chances of blocks on the surface of tool.
- In case the work piece is thin, make a choice of coarser grit. This is due to the fact that thin work pieces are susceptible to deformity as a result of heat.
Contact Area between the Workpiece and the Diamond Tool
In the
event of broadened contact area, make a choice of coarser grit. This will
ensure reduction in friction and heat.
Profile Grinding
This
order of business calls for finer grit. This is due to the fact that it will be
handy for keeping the form of working part of the diamond tool.
