Problems solved by technology

The grinding wheel of this thickness has the following disadvantages: First, because the thicker the thickness is, the resistance is greater when the workpiece is processed, and the efficiency is low.
Second, because the thickness of the processed workpiece is too thick, the loss of the processed workpiece is large, especially the loss of precious metals or jade and jadeite is a serious waste of resources.
The third is that the efficiency is low when the workpiece is thicker, the friction time between the grinding wheel and the processed workpiece is long, the metal section of the processed workpiece is easy to burn, and the non-metal is easy to carbonize, which has a great negative impact on the deep processing of the workpiece.
Moreover, the zirconium corundum resin grinding wheel disclosed in Chinese invention patent CN201210267278.6 and its preparation method do not consider increasing the strength of the structure

Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] The manufacturing method of the cutting and grinding resin grinding wheel of the present invention comprises the step of preparing molding material, the step of forming the semi-finished resin blank of the resin grinding wheel and the step of firing the finished product.

[0034] Step 1. Prepare molding materials:

[0035] When making molding materials, use high-adhesive phenolic resin and fine-grained abrasives (60#, 80#, 100#) to mix according to a certain ratio to make molding materials with moderate dry humidity, and park them for 4-8 hours for later use.

[0036] Among them, the raw materials and weight proportions used in the preparation of molding materials are: 30-50 parts of single crystal corundum, 50-70 parts of coated corundum, 20-25 parts of phenolic resin powder, 9-15 parts of phenolic resin liquid, 8-12 parts of cryolite,...

Abstract

The invention belongs to the technical field of resin grinding wheel manufacturing and relates to a manufacturing method of a resin grinding wheel for both cutting and grinding purposes. It includes the step of preparing the molding material, the step of molding the semi-finished resin grinding wheel blank and the step of firing the finished product. Among them, the molding material is made of phenolic resin material with high adhesion ability, and the molding material is poured in two times. The thickness of the grinding wheel is controlled below 2.5mm, so that Grinding wheels can both cut and grind. The beneficial effects of the invention are: convenience; avoiding the trouble of customers changing products back and forth, high processing efficiency; sharpness; saving labor and reducing burns to workpieces; saving energy; reducing thickness reduces the loss of workpieces; and is beneficial to workpieces. reprocessing; low cost and price, which is conducive to the promotion and application of the method of the present invention.

Description

technical field [0001] The invention belongs to the technical field of manufacturing resin grinding wheels, and relates to a method for manufacturing a resin grinding wheel capable of both cutting and grinding. Background technique [0002] For conventional resin grinding wheels, slicing is only suitable for processing workpieces by cutting. If it is used for grinding, it is easy to burst due to the strength of the product. Grinding discs are only suitable for grinding workpieces by grinding. If it is used for cutting , because the product is thicker, it takes time and effort to process and return waste (workpiece). But for the user, the surface of the workpiece processed by slicing may not be smooth, and there will be some burrs. At this time, these burrs will be polished off to make the surface of the workpiece smoother and easier to use, but the slice cannot be used for grinding. There is a need for a product that can both cut and polish. At present, the alternative pro...
