Example Embodiment

[0018] Example 1. Such as figure 1 , 3 As shown, it includes a ring-shaped metal substrate 1 and a grinding wheel grinding layer fixed on the outer peripheral surface of the metal substrate 1. The grinding wheel grinding layer is formed by splicing multiple grinding wheel grinding blocks 2, which are combined with diamond The agent is made by mixing, granulating, pressing, drying, pre-sintering, sintering (nucleation, crystallization, sintering), heat preservation, cooling and other processes. The binder used is made of mica microstructures with low thermal expansion coefficient, high toughness and high mechanical strength. Crystal glass is the basic glass, and titanium dioxide is used as a nucleating agent. The chemical composition of the basic glass is as follows: K 2 O 5~10%, MgO 10~18%, Al 2 O 3 10~20%, B 2 O 3 2~5%,TiO 2 1~4%, ZrO 2 1~4%, Na 2 O+K 2 O 3%, KF 5-12%, ZnO 4-8%, the rest is SiO 2 . When making, according to the above basic glass formula, using analytically...

Abstract

The invention discloses a grinding wheel with a split dovetail groove structure. The grinding wheel comprises an annular metal base body (1) and a grinding wheel grinding layer fixed on the peripheral surface of the metal base body (1), wherein the grinding wheel grinding layer is formed by combining a plurality of grinding wheel grinding blocks (2); dovetail grooves (3) are formed in the peripheral surface of the metal base body (1); a dovetail bugle (4) is arranged at the bottom of each grinding wheel grinding block (2); the dovetail bugles (4) of the grinding wheel grinding blocks (2) are embedded into the dovetail grooves (3) of the metal base body (1); the grinding wheel grinding blocks (2) are fixed to the metal base body (1); gaps (5) are formed in the embedded parts of the dovetail bugles (4) and the dovetail grooves (3). According to the grinding wheel, the split dovetail groove structure is adopted, so that materials are saved and the use cost is reduced; the grinding wheel has the characteristics that the production investment is small, the cost is low, the manufacturing process is easy to control, the scrap rate is low and the safety is good.

Description

technical field [0001] The invention relates to a grinding wheel, in particular to a dovetail groove split grinding wheel, which belongs to the technical field of grinding tools. Background technique [0002] At present, the grinding wheel used is mainly of integral structure, that is, the entire grinding wheel is composed of abrasive materials. This integral grinding wheel cannot be used after being worn to a certain extent. The remaining grinding wheel can only be discarded, and the entire grinding wheel needs to be replaced, resulting in material waste. , The utilization rate is low, and the use cost is increased. And when grinding at high speed, it is easy to be damaged by force, which is not safe. During the production process, due to reasons such as uneven molding and difficult control of sintering, the quality of the produced grinding wheels varies and the rejection rate is high. This is especially true for grinding wheels with larger diameters, such as grinding whe...
