Method for machining long shaft with round cross section

Abstract

The invention belongs to the field of manufacturing and machining a machine, and particularly relates to a method for machining a long shaft with a round cross section by using a centreless grinding lathe. The method comprises the following steps of: using the centreless grinding lathe, and using a machining device to grind a cutting sand wheel and a guide wheel of the centreless grinding lathe, so that the outer side face of the sand wheel is matched with the outer side face of a final finished product of the long shaft; and completing machining through a mounting process, a positioning process and a cutting modeling process. According to the method provided by the invention, the appearance of the long shaft type part to be machined is machined by grinding the shapes of the cutting sand wheel and the guide wheel. Compared with the conventional turning and machining method, the machining method provided by the invention has the advantages that the machining efficiency is improved, and the cost is reduced; furthermore, the process method has low requirements on skill levels of operators; the convenience and rapidness of machining can be realized; and the machining difficulty of the product is reduced; and meanwhile, the manufacturing precision, the surface quality and the product property can be greatly improved, and the method can be widely popularized in a machine manufacturing and machining field.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing and processing, and in particular relates to a method for processing a long axis with a circular cross section by using a centerless grinding machine. [0002] Background technique [0003] As the demand for mechanical parts becomes more and more diverse, the corresponding machining process methods are also constantly improving. When processing long-axis parts, the traditional process is mostly based on turning, especially for long-axis parts with a circular cross-section such as steps on the outer side and curved surfaces on the outer side, turning is used to process such parts. The products processed by the traditional process often have various problems such as shaft diameter steps, poor surface roughness, and the shaft diameter is deformed due to turning force, forming a waist shape, etc., and the production efficiency is low, and the requirements for the sharpening angle of the to...
