Abstract

The invention relates to an online deburring machining method of a component revolving groove structure, and belongs to the field of machining. The method analyzes the defects of a machining technology of a revolving groove structure on a revolving body, controls generation of such redundancies as burrs, flanges and acute edges with overall sizes not smaller than 0.5 mm in the machining process through adopting such methods as numerical control programming deburring, step-by-step deburring and polishing deburring, reduces the workload of redundancy removal in subsequent procedures, prevents the cleaning omitted possibility of machining redundancies, and is suitable for burr-free machining of the revolving groove structure of a mechanical structure component.

Description

technical field [0001] The invention relates to a processing technology for a rotary groove structure, in particular to a deburring process for a rotary groove structure on a rotary body, which belongs to the machining technology of structural elements in the field of mechanical processing, and is used for the rotary groove structure of mechanical structural elements Online deburring during machining. Background technique [0002] The rotary groove structure on the rotary body includes threads, grooves and steps. The threaded part is generally processed by turning, boring, fitter and other tools such as thread turning tool, tap, and wrench. The grooves and steps are generally processed by turning, boring and other tools such as grooving turning tools and face turning tools. [0003] During machining, the rotary thread, groove, and step structure are very easy to produce burrs, flashes, sharp edges and other redundant objects, but the processing technology of the rotary gro...
