Machining Titanium: Drilling

Welcome back to the series which is looking at how to machine and process titanium. In the first parts of the series we looked at the general considerations when machining titanium and then took a more indepth look into the individual types of machining and what needs to be considered. As a recap of the series so far:

Drilling is obviously one of the main machining activities performed with any metal let alone titanium. Drilling is used to create holes for fittings and fasteners, to remove excess material mad to also shape titanium as is the case with titanium hollow bars. Hollow bars are a very interesting form which has seen an increase in application over recent years. Hollow bars area type of titanium tube shape where the wall thickness cannot be formed by typical pipe extrusion methods. Instead the cavity is bored using a drill technique.
