Five major factors affecting poor surface roughness of metals

Metal surface roughness refers to the small spacing and small peak valley roughness of the processed surface. The roughness of its metal surface has a significant impact on the performance and use of mechanical components. Therefore, when producing metal workpieces, attention must be paid to surface roughness. There are five factors that affect metal surface roughness.
1. The processing quantity is too small, and the processing time is too short.
2. The groove of the grinding disc is too shallow, and the contact surface between the groove and the workpiece is too small.
3. The hardness of the grinding disc is too high or uneven, as well as sand holes and pores.
4. Excessive amount of grinding paste added or abrasive particles too coarse.
5. The groove of the grinding disc is too dirty, with iron filings or other debris.
