Materials have been broaching on various speeds of cutting are presented. Comparative research of influence the traditional broaching on low speeds of cutting (V=2 m/min) by the broaches from high speed steel R18 and the high-speed broaching (V=26 m/min) by the hard-alloy broaches VK8 on the change of intensity of wear of the broaches and formation of key parameters of quality of a superficial layer -a roughness and fatigue durability. Introduction of the high-speed broaching promotes the receipt of higher and stable parameters of quality of a superficial layer, increase of fatigue durability, reliability and a resource of gas-turbine engine parts and the minimal values of the tool wear intensity.
