Problems solved by technology

The existing grinding wheel cannot meet the requirement of single-sided force, and it is easy to cause the whole grinding wheel to fall off the circle. If it is light, it will damage the workpiece, and if it is serious, the grinding wheel will fly out when it rotates at a high speed, and it will hurt the operator.

Abstract

The invention discloses a cold saw grinding wheel of a single-bevel edge structure and a preparation method for the cold saw grinding wheel. The cold saw grinding wheel comprises a steel substrate andan annular grinding layer; on the steel substrate, a contact surface of the steel substrate and the annular grinding layer is of a horizontal Z-shaped structure; in the horizontal Z-shaped structure,an upper vertical surface is higher than a lower vertical surface; thus, from the appearance of the whole grinding wheel, the grinding layer is thick in one side and thin in the other side; by takinga grinding wheel mounting hole as the inside, a grinding surface bearing large stress is thick by a structure of which the outside is thick and the inside is thin; and the grinding layer is preparedfrom a resin binder and a grinding material. According to the cold saw grinding wheel disclosed by the invention, in order to increase a holding force between the binder and the substrate, an outer circle is knurled, the end face of the inner side of the outer circle is slotted and the joint of a grinding material layer and the substrate is plated with copper, thereby avoiding that the grinding wheel is liable to run off. Moreover, the structure is capable of using the grinding wheel to the maximum degree, thereby reducing cost; and moreover, the shape of the grinding wheel can be adjusted according to the shape of a to-be-processed object, and is suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of superhard abrasive grinding wheels, and in particular relates to a cold sawing grinding wheel with a single hypotenuse structure and a preparation method thereof. Background technique [0002] Cold sawing is a new type of saw blade. During the metal sawing process, the heat generated during the sawing process of the saw blade is transferred to the sawdust through the sawtooth, and the sawed workpiece and saw blade are kept cool. [0003] The teeth of the cold saw and its base are an integral structure, and the grinding wheel of the cold saw is directly toothed on the outer circle of the saw blade according to the requirements of the tooth shape. The grinding allowance of the cold saw grinding wheel is large, and the grinding resistance is also much larger than other grinding wheels. [0004] There is a big difference between the grinding method of cold saw grinding wheel and the existing conventional grinding meth...
