Problems solved by technology

However, the existing resin CBN grinding wheel must have a higher linear velocity to reflect the sharpness of the resin CBN grinding wheel. Therefore, it is necessary to modify the existing equipment of the current manufacturer and increase the spindle speed of the machine tool to increase the linear velocity of the grinding wheel.
In this way, it needs to spend more money to improve, which increases the operating cost of the manufacturer.

Abstract

The invention discloses a resin CBN (cubic boron nitride) grinding wheel for machining a saw blade base body. The resin CBN grinding wheel comprises a base body and an abrasive material layer. The abrasive material layer comprises the following raw materials in percent by volume: 15%-30% of CBN abrasive materials, 30%-45% of phenolic resin powder, 3%-6% of villiaumite grinding-aiding materials, 5%-15% of heat conduction materials, 5%-25% of metallic oxide, 2%-5% of solid lubricating materials and 4%-8% of pore forming materials. Compared with a common white corundum grinding wheel, the resin CBN grinding wheel is high in grinding amount, high in machining efficiency, long in finishing interval and low in speed of loss; and the grinding wheel changing frequency is reduced. Because the grinding wheel has high self-sharpening performance, burn injury and slow grinding of the CBN grinding wheel can be eliminated in a grinding process. On a grinding machine with low revolving speed of 1450 revolutions per minute, the CBN grinding wheel is used for replacing the common white corundum grinding wheel, and the saw blade base body can be quickly ground into a saw blade base body with the given size.

Description

technical field [0001] The invention belongs to the field of superhard abrasive grinding wheels, and in particular relates to a resin CBN grinding wheel used for processing saw blade substrates. Background technique [0002] Grinding wheel is the main tool for grinding, which is a porous object composed of abrasive and bonding agent. Resin grinding wheel is a grinding wheel whose binder is resin. It has the advantages of small grinding force, low grinding temperature, good self-sharpening, and high grinding efficiency. It is widely used in the grinding of hard and brittle materials such as cemented carbide, ceramics, and glass. Processing. [0003] The saw blade is the longest cutting tool used in product processing, consisting of a saw blade base and a cutter head. In the domestic market, the common white corundum grinding wheel is currently used to process the saw blade base, but the processing efficiency of the ordinary white corundum grinding wheel is low, the dressing...
