The invention discloses a preparation method of a composite
abrasive polishing disk for
diamond laser processing, which is characterized by comprising the following steps: mixing
diamond micro-
powder, aluminum
oxide and
silicon carbide, and adding a binding agent; carrying out ball milling and stirring on the mixed raw materials; carrying out
drying treatment and
compression molding on the mixed raw materials subjected to ball milling and stirring; and
sintering and post-
processing the formed blank. The method has the beneficial effects that the removal rate of the
diamond material is remarkably increased, meanwhile, the
surface roughness is reduced, and the
machining quality is improved; high
cutting force and
wear resistance are achieved, the service life is effectively prolonged, the replacement frequency is reduced, and the
machining stability is improved; the
mechanical strength and the stability are excellent, and the use reliability is improved; the
grinding material is ensured to be uniformly distributed, local excessive wear is avoided, the
processing consistency is improved, and the processing defects caused by non-uniform
polishing are reduced; and the manufacturing cost is reduced while the product quality is guaranteed, so that the method has remarkable economic advantages in large-scale production, and the market competitiveness is improved.
