Abstract

Reasonable terms to reduce the surface roughness of the hole through the use of internal grinding circuit with the location of the axis of rotation of the circle perpendicular to the axis of rotation of the hole. Calculations revealed that in this case, repeatedly increases the number of simultaneous abrasive grains participating in the formation of surface roughness, as compared with conventional internal grinding circuit - with the location of the axis of rotation parallel to the axis of rotation of the circle of the hole, which leads to a decrease in the surface roughness of the machined hole. Revealed regularities of processing errors hole at internal grinding and honing, due to the appearance in the technological system of elastic movements. Showing considerable technological capabilities honing holes in terms of improving the accuracy of processing is achieved by creating an elastic system in the construction of an abrasive tool - hone. The effectiveness of increasing the accuracy of the processing hole by using a flexible grinding wheel for internal grinding.
