Hydraulic Abrasive Tool and Its Incremental Dressing Method

Abstract

The invention relates to a water-based coagulation grinding tool and a additive repairing and finishing method thereof. The water-based coagulation grinding tool comprises the following raw materials of, in percentage by mass, 25%-35% of an abrasive material and 3%-7% of an anti-precipitating agent, 3%-7% of a hardening filler, 3%-7% of ferroferric oxide, and the balance base solution, wherein the base solution is a mixed solution prepared by mixing magnesium chloride and water according to a mass ratio of 1 to 49; the additive repairing and finishing method comprises the following steps that the worn grinding tool is put into a high-pressure mould, a stirred water-based abrasive material total mixed solution is poured; the high-pressure mould is sealed, and waiting is conducted for the solidification of the water-based abrasive material total mixed solution; and demolding, end surface grinding and finishing are conducted. The water-based coagulation grinding tool is high in overall hardness, the abrasive material is uniformly distributed in the grinding tool, and the machining capability of the surface of the whole grinding tool is consistent; the working face of the grinding tool has water absorption and water storage functions, so that the high-temperature degree of the grinding tool cannot be achieved in the working process, and the surface scorch of a workpiece in the machining process can be avoided; and in addition, the water-based coagulation grinding tool can be repeatedly used, the formula material is easy to obtain, the preparation method is simple to operate, low in difficulty and low in manufacturing cost.

Description

Technical field [0001] This application relates to the technical field of precision and ultra-precision processing, in particular to hydraulic abrasive tools and incremental dressing methods thereof. Background technique [0002] Traditional abrasive tools are usually made by bonding abrasives with a bonding agent. The manufacturing process of consolidated abrasives is usually as follows: dividing materials according to mass proportions, ingredients → mixing → forming through high-pressure molds → heating and curing → finishing, processing → qualified Inspection, etc., the processed abrasives have a certain strength and shape. Their strength, impact resistance, heat resistance and corrosion resistance are mainly determined by the performance of the bonding agent, and in different working environments, their performance is usually not There are big changes. Therefore, for workpieces of different materials, it is necessary to choose abrasive tools of different materials, and usual...

Problems solved by technology

Therefore, for workpieces of different materials, abrasive tools of different materials need to be selected, and usually the abrasive tools can only be trimmed by removing materials, but cannot be trimmed by adding materials, so that the abrasive tools can only be used as consumables and cannot be reused, and the cost of use is relatively high. high

In addition, during the grinding / polishing process, due to the rapid and high temperature rise, a large amount of water is required to cool the workpiece, which also seriously wastes water resources
