Evolution of Surface Roughness of Ti Plate in Abrasive and Abrasive-Less Polishing

Polishing the titanium plate is commonly necessary step before being used in many fields. Experiments of the titanium plate polished in the condition of including abrasive and existing abrasive are carried out to study the roughness of polished surface in given state. Surface roughness and morphology were investigated in experiments and experimental results were analyzed. In both experiments, the polished surface roughness value reduces with increase in processing time, and the detects on titanium plate before polishing decreases, which attributes to the mechanical and chemical tooth rising from lap between workpiece and polishing machine with the help of energy required. Material removal block in abrasive polishing is higher than that in case of existing abrasive. This helps to deepen the understanding of change in roughness of surface polished and indicates the promising operation technology for processing titanium in factory and workroom.
