To provide a high-speed broaching method with high accuracy in the semidry broaching, the dry broaching and the air-blow broaching in which a trace of mist is applied to a cutting blade of a broach cutter via a mist nozzle, or in the wet broaching in which a cutting oil is applied to the cutting blade of the broach cutter.
In this high-speed broaching method with high accuracy, the broach cutter 1 with a large number of cutting blades 11 disposed on the outer circumference of the body is used, a cutting blade 11 part of the broach cutter 1 is formed of powder high-speed steel or high-speed tool steel equivalent thereto, the broach cutter 1 with a TiAlN multi-layered coating coated on the cutting blades 11, a trace of mist or dry or air blow is applied to the cutting blades 11 via the mist nozzle 3, or a cutting oil is applied thereto, and the cutting speed is set to be as high as 20-60 m/min.
