This paper deals with the wear of the cutting edge, formation of chips and surface integrity of a workpiece turned in order to clarify the generation of mirrorlike surfaces (Al-Mg Alloy) with a relative long cutting distance. The tested diamond tools each have 2mm, 6mm and 10mm of the nose radius, As the experimental results showed, the wear of the cutting edges increases linearly during the first 100kms of the cutting distance, and afterward increases more gradually. After 900 km of the cutting distance. the main cutting edge is very blunt, but the tip of the tool remains somewhat sharp. Therefore, the surface roughness is still good, and the mirror finishing is possible. Such a thing can also be inferred from the observation of chips. On other hand. as to the surface integrity, the residual stress increases due to the wear of the cutting edge which intensifies the burnishing effect.
