Large-size radial ultrasonic auxiliary end face grinding abrasive disk

Abstract

The invention discloses a large-size radial ultrasonic auxiliary end face grinding abrasive disk. The abrasive disk mainly comprises an outer cover, an inner cover, a base disk, a plurality of magnetic supporting bases, an amplitude-change pole supporting base and ultrasonic vibration blocks. The multiple ultrasonic vibration blocks are evenly distributed in the circumferential direction of the base disk to be spliced into the large-size annular abrasive disk, and the radial ultrasonic vibration of the abrasive disk is achieved. The inner cover is installed on an inner ring of concentric circles of the base disk. The outer cover is installed on an outer ring concentric with the base disk. The base disk is in a concentric circle shape, and a motor main shaft is installed and connected in a center hole of the base disk. An abrasive block is driven by a motor to rotate so as to achieve end face grinding machining. The large-size radial ultrasonic auxiliary end face grinding abrasive disk can be used for ultrasonic auxiliary end face grinding and ultrasonic auxiliary milling and polishing, and therefore large batched ultrasonic end face grinding, milling and polishing on components can be achieved, and the machining efficiency and the machining precision of the components are greatly improved.

Description

technical field [0001] The invention relates to a grinding disc device, in particular to a large-size radial ultrasonic-assisted end face grinding grinding disc. Background technique [0002] Hard and brittle materials such as engineering ceramics, optical glass, and artificial crystals are widely used because of their high hardness, good chemical stability, resistance to oxidation, wear resistance, and corrosion resistance. However, these hard and brittle materials have extremely high hardness and brittleness, and their processing is very difficult. In particular, the processing of some thin photoelectric flat panel parts requires not only high shape accuracy, but also high processing surface quality. At present, the processing of such thin parts of hard and brittle materials mainly adopts the processing method of free abrasive double-sided grinding and polishing. However, due to the characteristics of the free abrasive grinding process itself, the shape accuracy of the pr...

Problems solved by technology

[0004] However, in the ultrasonic vibration-assisted grinding process, due to the characteristics of the ultrasonic vibration device itself, the ultrasonic vibration can only be applied to smaller workpieces or tools, and it is difficult to achieve ultrasonic vibration of large-sized grinding discs or workpieces.
