Reasons for poor surface roughness of steel balls
1. The processing volume is small and the
processing time is short.
2. The groove of the grinding disc is
shallow, and the contact surface between the groove and the workpiece is small.
3. The hardness of the grinding disc is too
high or uneven, and maybe there are trachoma and pores.
4. The added amount of abrasive paste is
too much, or the particle size of the abrasive is too coarse.
5. The groove of the grinding disc is too
dirty (there are iron filings or other debris).
The reasons for the poor local surface
roughness are: the groove of the rotating grinding disc is too shallow, and the
contact area of the workpiece is too small; the angle of the groove of the
grinding disc is too small, making the rotation of the workpiece inflexible;
the pressure applied by the upper grinding disc is too small, making Slippage
occurs between the workpiece and the grinding disc.
