The eccentric amount of the spiral hole milling apparatus and control method for detecting

The present invention discloses a milling holes in a spiral eccentric amount detecting means and a control method are helix milling hole processing art. The present invention comprises the steps of: mounting a laser detecting means, forming a detection region; start spiral hole milling device, so that the cutting edge part of the tool is located within the detection region; tool rotation, detecting the actual tool diameter d; the tool according to the actual diameter d and be processed nominal diameter D of the hole determine the theoretical amount of eccentricity, while the band is set according to the maximum allowed error tolerances eccentric hole to be machined; the magnitude of the eccentric spiral hole milling apparatus is adjusted to the theoretical amount of eccentricity E0; tool revolution, to detect the actual amount of eccentricity e ; the actual amount of eccentricity e e0 comparison with the theoretical amount of eccentricity, the helical milling passing hole machining; unqualified is adjusted until qualified. The present invention is to eliminate the influence of the machining tool aperture dimension error, improve the machining accuracy of the drilled hole, reduce scrap, and improve economic efficiency.
