DetailsAn 10mm thick Tin Lapping Polishing Faceting lap will not develop an orange peel surface common with some other tin laps. 1/2" arbor hole.Tin and its alloys are a class of materials, which have recrystallization temperatures below room temperature. This means that they do not work harden at room temperature. This is very important for embedding diamond into a lapping plate because the lapping material will not work harden during the charging process, thus allowing the diamond to embed into the lapping plate. The problem with most of these low recrystallization metals and alloys is that they do not effectively hold the diamond . The tin lapping plates get around this problem by having a very tightly controlled grain structure. As a result the embedded diamond gets pinned at the grain boundaries, which prevents the diamond from smearing and rolling. Thus the tin lapping plates produce a fixed diamond lapping process.Fixed diamond lapping processes have lower cutting profiles, are more efficient cutters (energy is applied to cutting vs. rolling), produce less wear on the lapping plates, and cut .The result is more characteristic of a polished surface.
