A grinding head for ultrasonically assisted grinding and polishing of end faces

Abstract

The invention discloses a grinding head capable of achieving end face ultrasound-assisted grinding and polishing. The grinding head is characterized by comprising a flange, a base, a magnetic bearing seat, an amplitude-change pole supporting seat and an ultrasound vibration block; the ultrasound vibration block is composed of an ultrasound transducer, an amplitude-change pole, magnetic poles and an abrasive block; the flange and the base are fixed; one end of the ultrasound vibration block is fixed to the base through the zero amplitude position of the amplitude-change pole; the other end of the ultrasound vibration block is used for supporting the magnetic poles at the tail end of the ultrasound vibration block through magnetic force via the magnetic supporting seat installed on the base; and the flange is installed on a motor in a connected manner, and the motor drives the abrasive block to rotate to grind an art product. The grinding head capable of achieving end face ultrasound-assisted grinding and polishing can be used for ultrasound-assisted end face grinding, lapping and polishing, and the machining efficiency and the machining accuracy of parts are greatly improved.

Description

technical field [0001] The invention relates to a grinding disc device, in particular to a grinding head for realizing ultrasonic-assisted grinding and polishing of an end face. Background technique [0002] In recent years, high precision processing of hard and brittle materials such as functional ceramics, quartz wafers, planar or polyhedral crystals and optical devices has been put forward. It also requires that the two ends of the material be strictly parallel, have no crystal orientation error, and have no metamorphic layer on the surface, and some even require nanoscale or higher processing accuracy and non-damaging surface processing quality. Grinding is a finishing and fairing method. It uses the free abrasive grains attached and embedded on the surface of the grinding tool to remove extremely small chips from the surface of the workpiece by means of the relative movement between the grinding tool and the workpiece under a certain pressure, so that the workpiece can...
