Online abrasive wheel dressing experiment system suitable for ultrasonic composite grinding of small hole inner circle

Abstract

An online abrasive wheel dressing experiment system suitable for ultrasonic composite grinding of a small hole inner circle comprises a machine tool workbench, a machine tool main shaft and a precise filtering oil mist lubrication device arranged on the side face of a machine tool. The machine tool main shaft is vertically arranged above the machine tool workbench. The machine tool workbench is provided with a frequency-variable speed-adjustable abrasive wheel dressing device, an abrasive wheel electrolytic in-process dressing (ELID) rough dressing sharpening device and a workpiece clamping and rotating device. The machine tool main shaft is provided with an ultrasonic vibration cutter device. A fixing frame capable of synchronously moving up and down with the machine tool main shaft is arranged outside the machine tool main shaft, an online ELID dressing sharpening device is arranged outside the middle of the fixing frame, and an upper induction disc and a lower induction disc are arranged outside the lower portion of the fixing frame. Online abrasive wheel dressing is carried out while the ultrasonic vibration grinding is achieved, a multi-technology combined efficient mirror finishing technology is realized, the technology support is provided for the application of efficient ultra-smooth surface machining of hard and brittle materials in the high technology fields such as national defense and aerospace, and the online abrasive wheel dressing experiment system has high theoretical value and practical value.

Description

technical field [0001] The invention belongs to the technical field of high-efficiency mirror grinding of hard and brittle materials, and in particular relates to an on-line dressing experiment system of a grinding wheel suitable for ultrasonic compound grinding of inner circles of small holes. Background technique [0002] As an important branch of ultra-precision processing technology, high-efficiency processing technology for mirror surfaces of hard and brittle materials is of great significance to the development of cutting-edge science and technology such as aerospace, national defense, information, microelectronics and optoelectronics. [0003] In recent decades, the most eye-catching mirror surface processing technology in the world is the online electrolytic dressing (electrolytic in-process dressing, ELID) mirror grinding technology. ELID grinding is the use of nonlinear electrolytic dressing and the dynamic balance of the electrolytic inhibition effect of the oxide...
