Abstract

The milling machine with multiple cutting heads is used for machining long blades for turbines. The blades (1) are mounted vertically in a row in upper (21) and lower (22) spindles. Each blade is supported at an intermediate point by an enclosing ring (23) and the rings are mounted on a vertical slide (157). The slide is positioned so that it is as close as possible to the cutter (12) to provide rigid support during machining. The slide is moved as the cutters traverse the length of the blades to maintain this support.
