Embodiment Construction

[0071] The present invention will be further described below in conjunction with accompanying drawing and embodiment:

[0072] Such as Figure 1 ~ Figure 4 As shown, the cerium oxide polishing disc of the present embodiment is composed of a circular chassis 1, a central hole 2, a side hole 3 and a grinding head 4; the grinding head 4 is composed of an even number of identical fan-shaped blocks whose tops are arc-shaped; Chassis 1 is fixedly connected to the rotating disk of the polishing machine through central hole 2 and side hole 3; the bottom of grinding head 4 is bonded to chassis 1 with adhesive A, and the upper half of the edge is chamfered, and the angle of chamfering is at the same angle as the vertical direction. The angle of 30 degrees; the grinding head 4 is made by radially bonding 40 to 150 layers of grinding discs with adhesive B, and processed. The grinding discs are at right angles to one side of the sector and 60 degrees to the other side of the sector, wherei...

Abstract

A polishing cerium oxide disk is composed of circular substrate disk, central hole, holes on edge and abrasing head, and is prepared from chemical fibre cloth through immersing in resin, adhering squeezing and shaping. Its advantages include long service life, high tear strength, and shear strength, high firmness of abrasing head, and low cost.

Description

Technical field: [0001] The invention relates to a cerium oxide polishing disk, which is specifically made by using chemical fiber cloth as a base material, adding glue for impregnating the base material, and then bonding, pressing and forming with an adhesive. The invention also relates to the cerium oxide polishing disc. Disc manufacturing method. Background technique: [0002] During the production process of the display screens in TVs and computers, the glass bulb needs to be polished. The current practice is to fix the polishing disc on the turntable of the polishing machine, and use cerium oxide as a polishing agent for polishing. Cerium oxide has good thermal conductivity and poor electrical conductivity. Most of the polishing discs used are imported consumable parts. The number of glass bulbs that can be polished by one polishing disc is determined by the quality of the grinding head and chassis used on the polishing disc. Generally, a polishing disk can only be us...
