The company has developed a special tool and processing technology for the processing of railway wheel holes. The tool includes a blade and a blade holder for fixing the blade. The blade plane is a regular octagon. The eight sides of the regular octagon are set with four main cutting edges and four wiper edges. The blade holder has a blade fixing groove. The included angle of the axis is 45 degrees; when cutting, the square blade adopts a main declination angle of 45 degrees and a secondary declination angle of 0 degrees with the feed direction, the feed speed is 160~220mm/min, and the speed is 70~100r /min, the rear end of the wiper protrudes 0.01~0.03mm from the front end relative to the feed direction. The invention adopts a regular eight-square blade and a special tool bar for fixing, and the blade adopts a main declination angle of 45 degrees with the feeding direction and a secondary declination angle of 0 degrees when cutting. Cutting feed rate, the present invention can greatly improve the processing efficiency. This process can be widely used in the finishing of railway wagon wheels.
