The invention discloses a high-speed face milling cutter for reducing resistance and noises by utilizing micro grooves in surface. The high-speed face milling cutter comprises a cutter body, wherein the cutter body is provided with a plurality of micro grooves, and the directions of the micro grooves are parallel with the rotation direction of the cutter body; and the micro grooves are machined in the external circular surface of the cuter body by adopting a precision turning tool, are parallel with the rotation direction of the cutter body, and are of microstructures, or a microstructural thin polymer film layer is pasted on the external circular surface of the cutter body, and the bonding strength between the film layer and the cutter body can overcome the centrifugal force under high rotary speed. According to the high-speed face milling cutter provided by the invention, a pair of reversed secondary whorls are arranged on two sides of the top point of each groove by utilizing the microstructural grooves in the surface of the cutter body while cutting work is completed; and turbulent burst intensity can be greatly reduced by the reversed vortex pairs, so that a resistance and noise reduction effect by trubulent flow is achieved, and the air resistance in a high speed manufacturing procedure and the noise to environment are reduced.
Description
technical field [0001] The invention relates to a cutting technology, in particular to a high-speed face milling cutter which utilizes surface micro-grooves to reduce drag and noise. Background technique [0002] At present, high-speed face milling cutters have been widely used in the manufacturing fields of automobiles, aerospace, molds, etc. The speed reaches 7500 m / min. When the high-speed face milling cutter rotates at high speed, due to the interaction between the face milling cutter and the air, it induces the unsteady flow of the surrounding air, which produces large noise and air resistance, which affects the health of the operator and increases energy consumption. At present, the main methods for noise reduction of high-speed face milling cutters include the design of unequal pitch milling cutters, and the sound insulation design of machine tool shields, etc., but there is no relevant report on the drag reduction of high-speed milling cutters. [0003] When the hi...
