Multi-dimensional ultrasonic assisted magneto-rheological precision polishing machine tool and machining method

Abstract

The invention relates to a multi-dimensional ultrasonic assisted magneto-rheological precision polishing machine tool and a machining method, and belongs to the technical field of polishing machine tools. Two sets of Y-direction moving rails are separately fixed on the left side and the right side of a machine tool base 1, two Z-direction fixing bottom plates are separately fixed on the Y-direction moving rails arranged on the left side and the right side of the machine tool base 1, two Z-direction moving rails are separately fixed on the Z-direction fixing bottom plates, X-direction fixing bottom plates are separately fixed on the two Z-direction moving rails, and X-direction moving rails are fixed on the upper sides and the lower sides of the X-direction fixing bottom plates; and a magnetorheological fluid circulating device is fixedly arranged behind the middle of the machine tool base, a rotating workbench is fixedly arranged in front of the middle of the machine tool base, tool head mounting bottom plates are fixed on the X-direction moving rails, and tool heads are fixed on the tool head mounting bottom plates. The polishing machine has the advantages that polishing machiningis carried out at the same time in three different directions, so that the machining area at the same time is larger, the rotation motion of a grinding head enables the polishing machining to be morecomprehensive and thorough, and the polishing machining efficiency and the machining precision are improved.

Description

technical field [0001] The invention belongs to the technical field of lapping and polishing machine tools, and in particular relates to a multi-dimensional ultrasonic-assisted magnetorheological precision lapping and polishing machine tool and a processing method. Background technique [0002] With the development and application of optical technology, the precision requirements for the surface of optical components are getting higher and higher. However, because most of the materials used in optical components are brittle and hard, traditional processing methods have been unable to meet the requirements for such material parts. high-precision and high-efficiency processing requirements. [0003] At present, the processing of optical components, such as airbag polishing and ultrasonic polishing, is mostly limited by its own conditions, and it is impossible to process small curvature optical surfaces, and the polishing efficiency is not high; in recent years, ultrasonic magn...
