FINISHING GASHER SOLUTIONS (INTERNAL & EXTERNAL) General Description The finishing of gears has been practiced successfully with Tungaloy tools for many years now. For the finishing operation all over the world tools with a convex (internal gear production) or concave (external gear production) form are applied. The tools, as well as the inserts are within very narrow tolerances to achieve the required accuracy of the tooth gap. During the machining of the tooth gap, a lot of material is removed from the tooth base, whereas in the involute area rather a finishing operation and polishing of the surface are carried out. This complex machining operation was reason enough to develop a tool concept suitable for the various cutting requirements. The result is a tool with different radial angles as well as overlapping insert geometries. These new tools obtain fully effective teeth at the root of the tooth and half effective teeth at the tooth flank thus optimizing the chip thickness. The advantages of this Tungaloy design are reflected in a longer tool life, improved surface finish, lower heat development on the component, as well as in a reduction of the cutting material costs. 14
