Attention must be paid to the accurate selection of grinding wheels and trimming wheels.
In the process of internal grinding, the machining quality is affected by small grinding wheel and long grinding rod. In order to facilitate the smooth surface of the inner hole, the following two points should be paid attention to when trimming the grinding wheel:
1) the diamond tip must be sharp, in order to trim the smooth and multi edged abrasive particles, so that the cutting is brisk and the surface roughness of the grinding surface is reduced.
2) if the cylindrical grinder is used to grind the inner hole, the height of the grinding wheel dresser center shall be as the standard of the cylindrical grinding wheel center, and it is 1 to 2 mm lower than the center. Among the use of the internal grinding, because of its rotation direction is opposite to the direction of the cylindrical grinding wheel head, therefore, must take the diamond knife 1 to 2mm higher than the Center, so as to maintain the stability in the trimming, avoid eating knife phenomenon, and it is also beneficial to the smoothness of the wheel rim, improve the accuracy and reduce the surface roughness.
