brasive particle size

grinding tool surface roughness easier although guaranteed, but prone to chipping blade, serrated blade degree difficult to reduce. Tool edge ultra-precision machining requirements under the microscope at 500 times without chipping, so to optimize all aspects of  the grinding process, in order to obtain a perfect straight edge.
Abrasive powder particle size and  ceramic flap disc surface condition of the grinding disc grinding quality of
As can be seen, the coarse large impact on the blade, serrated edge grinding degree is large, basically difficult to grind the cutting edge without chipping; while the use of powder, the grinding blade after a few minutes that is changed have straight, zigzag degree tends to zero.
Newly manufactured grinding disc machining accuracy due to limitations of its disk roughness greater stability  cut off wheel for grinding have a certain influence. In addition, just coated abrasive particles in the disk itself is also poor contour. After a period of grinding, the high point on the disk surface is ground flat, the larger abrasive particles may also be broken or shovel from the disk, so that the contour of the abrasive grains is improved, the blade serrated reduced degree of stability. So for the blade or diamond tool grinding and other key processes, grinding disc must be in a stable on the disk.
