Abstract

The invention discloses a five-axis two-dimensional ultrasonic polishing machine tool for optical curved face machining. The machine tool is composed of a rack, a three-dimensional moving device, a rotary ultrasonic vibration polishing device, a rotary workbench, a polishing liquid ultrasonic atomizing and applying device and an on-line workpiece detection device. When the machine tool is used, the amplitude of the ultrasonic vibration polishing device is obtained according to the calculation formula (please see the formula in the description); five-axis linkage is achieved through a program control system, and the axis of a polishing head is made to always coincide with the normal line of a workpiece polishing point; a 45-degree included angle is kept between the jetting direction of polishing liquid and the normal line of the polishing point. The polishing machine tool has the advantages that ultrasonic energy transmission is concentrated, the contact stress between the surface of the polishing head and the surface of a workpiece is uniform, the polishing precision is high, the removal rate in the polishing process is high, the utilization rate of the polishing liquid is high, and the polishing precision of the workpiece can be detected on line.

Description

technical field [0001] The invention relates to a polishing machine, in particular to a five-axis two-dimensional ultrasonic polishing machine tool for optical curved surface processing and a use method thereof. Background technique [0002] With the development of industrial technology, hard and brittle materials have shown broad application prospects in the fields of aerospace, automobiles, molds, optics, and semiconductors. Optical glass is often used to make reconnaissance satellite camera lenses, stealth radar search mirrors, high-speed aircraft windows, large mirrors for astronomical telescopes, and optical lenses and prisms in laser emitting devices. Conventional machining of optical elements of hard and brittle materials is very difficult, and is usually obtained through ultra-precision grinding, polishing and ultra-precision grinding, but this method takes a long time and costs a lot. In order to solve this processing problem, an ultrasonic processing method began ...
