Abstract

The invention discloses a vitreous bond, a standard hardness block and a manufacturing method thereof, and relates to the technical field of grinding wheel detection and calibration. The vitreous bonding agent provided by the invention consists of 10-40 parts of glass powder, 1-20 parts of borax and 1-3 parts of zinc oxide. The vitreous bonding agent provided by the invention can provide stable bonding force, avoiding the change of the properties of the bonding agent due to unstable components of traditional vitrified bonding agents such as clay and feldspar. Standard hardness blocks were manufactured by using the above-mentioned vitreous bond and using a liquid stirring process. The abrasive material of the standard hardness block provided by the invention is evenly distributed, and the hardness uniformity difference of the same batch of hardness block products is small, which can be used to accurately calibrate the accuracy of the sandblasting hardness machine within the entire detection range.

Description

technical field [0001] The invention belongs to the technical field of grinding wheel detection and calibration, and in particular relates to a vitreous bond, a standard hardness block and a manufacturing method thereof. Background technique [0002] Ordinary grinding wheels are composed of abrasives and bonds, and hardness is an important parameter when selecting and using grinding wheels. If the hardness of the grinding wheel is harder than the workpiece, it will lead to poor self-sharpening of the grinding wheel, lower grinding efficiency, lower grinding quality and even burn the workpiece; if the hardness of the grinding wheel is softer than the workpiece, the grinding wheel will be consumed Fast, affecting the machining accuracy. It is very important to choose a grinding wheel with the appropriate hardness according to the workpiece. [0003] The sandblasting hardness machine is a special equipment for testing the hardness of the grinding wheel. Its working principle ...
