The Investigation on Small Hole Drilling-Grinding in Glass and Ceramic

Abstract:

Making holes in glass or ceramic with conventional twist drills is difficult because of the hard and brittle properties of the workpieces, but the drilling-grinding process with diamond core-tools has found application in the field due to its high efficiency and low cost. However, small hole drilling-grinding with the core tools is still a challenge because the small core tools have a limited strength and chip-removal capacity. In this paper, the small hole drilling-grinding in glass and ceramic by diamond core-tools with 4mm diameter is experimentally investigated, the drilling-grinding force and heat are measured and calculated, the performances of two types of electroplating diamond core tools are compared.
