The size of the diamond particle size directly affects the processing efficiency, processing effect and service life of the tool. Under normal circumstances, if the diamond particle size is coarse, the depth of the grinding workpiece will be large and the machining efficiency will be high, but the machining accuracy of the workpiece will be poor; on the contrary, if the diamond particle size is fine, the machining efficiency will be low and the machining accuracy of the workpiece will be high. The general principle for selecting the diamond particle size is: on the premise of satisfying the machining accuracy, try to use coarse-grained diamond to improve the efficiency. In actual use, the user also attaches great importance to the life of the tool, which requires consideration of the size and composition of diamond particle size, diamond quality, diamond concentration, bond formulation, and even the structural size of the tool and processing conditions. It should be said that for the diamond tools determined by the processing conditions and the formulation of the binder, there is always the best particle size and composition, at which time the processing efficiency is the highest and the consumption is the least.

It is necessary to use coarse-grained diamond to improve the efficiency of the tool, but the diamond of good quality must be selected, otherwise the diamond will be easily broken or fall off during use, and the high cutting edge cannot be maintained, and the efficiency will drop or even fail to work.

Generally, for rough machining tools such as sawing, drilling, dressing, etc., the particle size of diamond used is 30/35~70/80; 170/200; fine grinding tools mostly use 200/230~325/400 particle size.

In the actual selection of diamond particle size, the variety of tools, use conditions, diamond quality, diamond concentration and bond formulation should also be considered comprehensively.
