Abstract

A technology for machining the shaped surface of engineered ceramic blade by numerally controlled developing, creep advance and ultrasonic grinding features that the ceramic work piece is ultrasonically vibrating in Z axis, the grinding disc is rotating around main shaft perpendicular-to Z axis at high speed, and under the control of numeral control system, the grinding disc and work piece are relatively moving in X, Y, Z directions and rotating around Z axis. Its apparatus is composed of a numerally controlled 5-axle machine tool, numeral control system, grinding disc and its main shaft, frequency-regulatable motor and its control system and ultrasonic vibrating system.

Description

1. Technical field: [0001] The present invention "Numerical Control Generating and Creeping Ultrasonic Grinding Process and Device for the Surface of Engineering Ceramic Blade" belongs to a special processing method and device for the profile of engineering ceramic materials. 2. Background technology: [0002] With the development of modern science and technology, engineering structural ceramics are increasingly used in new products, such as spark plugs for internal combustion engines, high-temperature bearings, sealing rings for chemical and petroleum pumps, high-temperature crucibles, rockets, missile shrouds, rotors Engine scrapers and even ceramic knives have become indispensable new materials in high-tech fields such as modern industry, national defense and aerospace. However, the processing of engineering ceramics, especially the forming process, is still very difficult and hinders its expanded application. Complicated formed components made of these materials are gen...
