Titanium alloys have great potential in ultra-precision situations due to the excellent properties, such as high corrosion resistance, high specific-strength and high biocompatibility. However, the application of titanium alloys in ultra-precision field is limited by the poor machinability. There are difficulties in obtaining the optical surface. In this study, the possibility for obtaining optically graded surfaces of titanium alloys by ultra-precision polishing was investigated. Before the ultra-precision polishing, ultra-precision turning with a single point diamond tool was used to get all sample surfaces. But, titanium alloy is difficult to obtain good surface quality by ultra-precision diamond turning. The samples results confirmed that most of the surface roughness values are higher than 30 nm. In order to explore the polishing process, a large number of ultra-precision polishing experiments were conducted. In addition, the effects of different ultra-precision polishing parameters on the surface profiles of titanium alloy Ti6Al4V were investigated in depth. The results show that the average values of surface roughness of titanium alloy parts with ultra-precision turning can be further reduced by 70% or so by ultra-precision polishing. Using a reasonable combination of high spindle speed and large cutting depth, the value of surface roughness can even be lower than 2 nm.

Because of the excellent properties, the application of titanium alloys in the ultraprecision field is attracting more and more attention of scholars. However, the poor machinability of titanium alloys limited their application. To reveal the mechanism of titanium alloy Ti6Al4V in ultraprecision polishing, the ultraprecision polishing tests of Ti6Al4V alloy have been carried out after the ultraprecision turning tests. The effect of particle size on the surface roughness has been investigated through the tests. In addition, a 2D finite element model was presented to investigate the ultraprecision polishing process. At the same time, the effect of particle size on the ultraprecision polishing of Ti6Al4V was analyzed by the simulation. The simulation results showed that there existed a critical particle size that can affect the ultraprecision polishing process of Ti6Al4V alloy. The contact process of particle and the workpiece can be regarded as a cutting process when the radius particle is lower than the critical size, while the contact process is a ploughing process when the radius particle is larger than the critical size. The experiments’ results proved that the better surface can be obtained if the radius of particles is slightly larger than the critical size.
