turbine bucket milled to a 16 micro-inch finish in one pass! Blade on right is
a gas turbine rotor milled to finish from a rough forging in one pass to a 16
mirco-inch finish (.4 micro-meter finish)! The machined blades were produced at
high speed, in one pass, using the patented THOMAS MILL, and THOMAS machining
