Rolling the inner hole with a rolling bearing

The hole in the cylinder of the motor brake produced by our factory is Φ80_0~(+0.03)mm, the boring hole of 187mm, and the bottom has an empty sipe with a width of 8mm, and the surface roughness is required to be R_a0.8. After turning, our factory does not have a dedicated internal grinding machine for internal hole grinding. Due to the tight time and small batch size, there is no need to make a special inner hole rolling tool or honing head. So we used a rolling bearing to make a simple inner hole rolling tool for the test roll, the effect is good, it is introduced as follows.
