BILTZ has developed an extensive range of specialised tools for roughing, semi-finishing and finishing steps involved in the production of impellors and turbine blades. Tools include torrus cutters, tapered cutters, tapered ball nose cutters and tapered torus cutters, including oval faced form cutters. Torrus cutters for the semifinishing and finishing of turbine blades feature 4 to 12 flutes with unequal indexing to minimise vibrations while machining. Designs include corner radius, straight, 6°, and 8° taper angle versions. Tapered ball nose cutters include special designs, which incorporates 2 flutes, 3 flutes, 4 flutes and 6 flutes with centre cutting edges that provides extra tool stability and improved surface finish of turbine blades. Taper angles range from 4° to 10°. Oval faced form cutters are exceptionally efficient finishing tools. The oval form simulates the attributes of ball nose end mills having a diameter range of 100-200 mm. This allows for double the axial cut vs a standard ball nose end mills, resulting in a superior surface finish.
