Ultraprecise drum-shaped roller and processing method thereof

Abstract

The invention provides a processing method for an ultraprecise drum-shaped roller. In the method, a special grinding machine is not needed and by a high-speed cutting technology, a grinding machine is replaced by a machine tool, and the method is short in a production preparation cycle and low in production cost. The method comprises the following steps of: 1) performing rough tuning on a forged and pressed blank and forming; 2) performing finishing turning on an inner hole and an excircle of a workpiece by using a numerical control machine tool with general precision; 3) hardening the surface; 4) performing finishing turning on the inner hole of the workpiece by using a numerical control machine tool with high precision, rigidity and rotation speed performance; 5) performing finishing turning on a drum-shaped outer profile of the workpiece by taking the inner hole as a reference and using the digital control machine tool with high precision, rigidity and rotation speed performance; and 6) detecting flaws of parts by a wet flaw detection method and demagnetizing the parts. The invention also provides the ultraprecise drum-shaped roller processed by the method, and the end point ofan arc side bus of the drum-shaped roller is in tangential transition connection with the end face of the roller.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a method for processing an ultra-precision drum-shaped roller and an ultra-precision drum-shaped roller processed by the method. Background technique [0002] Ultra-precision drum rollers are more and more widely used because of their longer service life than ordinary rollers. The shape of ultra-precision drum rollers is not limited to circular arcs with a chord height of only 0.003-0.008mm and a slightly convex arc. , and more are compound curves including arcs and straight lines, which are more difficult to process. [0003] In the prior art, the processing of the drum-shaped roller generally has the following several processing methods: 1. The drum shape is formed and processed by a special cylindrical grinder. 2. The drum shape is processed by centerless grinding. 3. The drum shape is profiling processed by a convex super-finishing machine. This type of proce...
