Problems solved by technology

[0002] Commonly used grinding wheels do not have a firm chemical-metallurgical bond on the bonding surface between the coated metal and the substrate and the abrasive. The abrasive is actually only mechanically embedded and inlaid, so the holding force is small, and the abrasive particles are heavily loaded and easy to fall off, resulting in overall failure; The holding force must incr

Abstract

The invention relates to a special grinding wheel formula for a tobacco blanket machine, which comprises the following components in parts by weight: 100 parts of grinding material, 9-13 parts of binding agent, 2-4 parts of dextrin powder and 3-6 parts of wetting agent, wherein the binding agent consists of Jiyong clay powder, Shangluo feldspar powder, borax glass powder and ferric oxide rouge, and comprises the following chemical ingredients in percentage by weight: 21.0-24.0% of Al2O3, 52.0-56.0% of SiO2, 1.0-1.5% of Fe2O3, 5.5-7.5% of B2O3, 0-0.5% of CaO, 0-0.5% of MgO and 10.0-14.0% of K2O and Na2O. The formula enables the binding agent to have the advantages of proper refractability, favorable flowability, high mechanical strength, favorable high-temperature wetting quality and the like; the prepared grinding wheel and the binding agent are sufficiently liquefied under high-temperature fusion catalyzing condition, and evenly wrap the grinding grains; and the prepared grinding wheel has the advantages of favorable grinding performance, high grinding precision and long service life.

Description

Technical field: [0001] The invention relates to a grinding wheel formula, in particular to a special grinding wheel formula for a tobacco cutting machine. Background technique: [0002] Commonly used grinding wheels do not have a firm chemical-metallurgical bond on the bonding surface between the coated metal and the substrate and the abrasive. The abrasive is actually only mechanically embedded and inlaid, so the holding force is small, and the abrasive particles are heavily loaded and easy to fall off, resulting in overall failure; The holding force must increase the thickness of the coating. As a result, the exposed height of the abrasive grains is reduced, the grinding wheel is prone to clogging, the heat dissipation effect is poor, and the surface of the workpiece is prone to burns. At present, the domestic grinding wheel manufacturing has not realized the optimal design of the grinding wheel formula according to the processing conditions. Invention content: [0003...
