Embodiment Construction

[0021] A high-efficiency preparation process for the abrasive layer of a vitrified bond superhard material grinding wheel, comprising the following steps:

[0022] (1) Pressing process: Using a horizontal overall mold, first adjust the size of the cavity, then put the mixed powder into the cavity, and finally the upper and lower heads are driven into the cavity at the same time by the press. The powder is moved and pressed, and the abrasive layer is formed by pressing at one time;

[0023] (2) Sintering: Use a sintering furnace to sinter the abrasive layer into an abrasive block; determine the temperature process curve according to different products, mainly consisting of a heating stage, a heat preservation stage, and a cooling stage.

[0024] (3) Cutting: Place the abrasive block on a special fixture, and use laser cutting equipment to cut the abrasive block into abrasive layers for grinding wheels whose shape and size meet the requirements.

[0025] Such as figure 1 with ...

Abstract

The invention belongs to the technical field of grinding wheel manufacturing technologies, and provides an efficient manufacturing technology of abrasive material layers of a ceramic bonding agent ultra-hard material grinding wheel in order to solve the technical problems that in the process of a traditional grinding wheel block manufacturing technology, the labor amount is large, the efficiency is low, labor cost is high, and the technological stability is poor. The efficiency manufacturing technology comprises the following steps of (1) pressing, (2) sintering and (3) cutting, wherein in the step (1), a horizontal integrated die is adopted, and abrasive material layers are formed through one-time pressing; in the step (2), a sintering furnace is used for sintering the abrasive material layers into an abrasive material block; in the step (3), the abrasive material block is placed onto a special fixture, and laser cutting equipment is used for cutting the abrasive material block into abrasive material layers, with the shape and the size meeting the requirements, for the grinding wheel. The efficient manufacturing technology is simple in operation, the pressing forming times of the grinding wheel block are reduced, the forming success rate is improved, the forming technology stability is guaranteed, meanwhile, the labor amount is reduced, labor cost is saved and the production efficiency is improved to a large extent.

Description

technical field [0001] The invention belongs to the technical field of grinding wheel manufacturing technology, and in particular relates to a high-efficiency preparation process of a vitrified bond superhard material grinding wheel abrasive layer. Background technique [0002] Laser cutting equipment uses high-energy laser beams to make the surface of the workpiece reach extremely high temperatures in a short period of time, thereby melting or vaporizing the material, and its auxiliary high-speed airflow blows off the molten material to achieve cutting of the workpiece. Due to the high speed and high precision of laser cutting, it is widely used in light industry sheet metal processing and heavy industry fields such as construction machinery, bridges, shipbuilding, etc., especially for the cutting of hard and brittle vitrified bond superhard material grinding wheel abrasive layer, laser cutting It is an ideal processing method. [0003] The abrasive layer is the main part ...
