Star SU's Single-Flute Gundrills Suitable for Medical Device Machining
Star SU’s solid carbide gundrills are designed for work in medical-grade materials such as titanium and stainless steel. The single-flute tools meet part print requirements for medical devices and instruments. The company reports tool life improvement in both titanium (6Al-4V) and 440 stainless steel, driven by selection of carbide grade, surface finish, edge preparation and coating.
The solid carbide gundrills are made in a two-piece design. The tip and body are a single piece of carbide brazed into the driver/shank, while the ﬂute is ground down the length of the head and body. The rigid gundrills are equipped with high-pressure coolant delivery capabilities. The tools provide coolant delivery holes in diameters ranging from 0.700 mm (0.028").
Reducing cutting fluid use offers the chance for considerable cost savings. Tool life may even improve.
Simple process considerations can increase your productivity in milling titanium alloys.
Applying ceramic inserts is not a simple substitution of one cutting tool material for another. There are significant process considerations that shops should examine carefully in order to realize performance and tool life expectations from ceramic inserts. Here's a look at some of the ways they are used.
