Technical Field

The invention relates to the field of grinding wheel grinding, in particular to a diamond grinding wheel device for grinding optical glass based on adsorption cooling.

Technical Field

The grinding wheel is used as a soul of grinding processing, plays a core role in the grinding processing process and generally consists of an abrasive, a bonding agent and a shaft hole. Because its surface of emery wheel is more crude to the tiny granule after the grinding is got rid of is attached to the emery wheel surface easily, will influence grinding performance on the one hand, and tiny granule causes certain fish tail to the work piece easily, thereby influences grinding precision, and the dust granule that adheres to with emery wheel outer fringe face generally brushes with the help of the foreign object and falls, and is comparatively troublesome, and frequent operation influences work piece grinding efficiency easily.

In the grinding process, heat on the surface of the workpiece is continuously accumulated along with the continuous grinding process, so that local high temperature is formed, and the integrity and usability of the surface of the workpiece are seriously damaged by the local high temperature. Workpieces also often experience dimensional and shape accuracy errors due to cumulative temperature rise during grinding. The solution is often to provide sufficient grinding fluid to the grinding zone. The grinding wheel only adopts a single cooling mode of external cooling liquid input, the cooling efficiency is not high, and timely response can not be made to complex working conditions appearing in the grinding process, but the grinding wheel rotating at a high speed drives the air around the grinding wheel to form an air barrier layer which prevents the grinding liquid from entering, so that the amount of the effective grinding liquid which can effectively enter a grinding area is more limited, a large amount of heat accumulation or even heat damage in the grinding area is directly caused, and the performance and the processing effect of the grinding wheel are influenced.

The grinding process of the optical element comprises a large amount of material removal, which can cause the problems of abrasion of the grinding wheel, blockage of the grinding wheel, unbalanced jump and the like. The grinding wheel dressing work is effectively carried out in time to keep the sharpness of the abrasive particles, the chip containing space and the processing capacity on the surface of the grinding tool, and then the grinding processing can be smoothly carried out. In order to remove the machining traces left on the surface of the optical glass after grinding and obtain a high-quality surface, a subsequent precision polishing process is required, but the removal rate and the machining efficiency of the polishing process are low, so that the key points of improving the grinding quality and reducing the polishing time are the optical glass machining. The grinding process of the optical element comprises a large amount of material removal, which can cause the problems of abrasion of the grinding wheel, blockage of the grinding wheel, unbalanced jump and the like. The work of removing the abrasive dust is effectively carried out in time to keep the sharpness of the abrasive particles on the surface of the grinding tool, the space for containing the abrasive dust and the processing capacity, and then the grinding processing can be smoothly carried out.

The principle of the disclosed coated abrasive grain insert type brazing grinding wheel is that a plurality of radiating grooves are uniformly formed in the side walls of a grinding wheel base and a cover plate to promote the circulation of grinding liquid and enhance the heat exchange of a grinding area, and a diamond film is coated on the surface of a common abrasive to reduce the production cost, so that the grinding wheel solves the problems of heat dissipation and abrasion of the grinding wheel to a certain extent. However, the technical scheme still has the following problems: the cooling mode of the grinding wheel is not changed fundamentally, and a large amount of heat is accumulated and even heat damage is caused only by inputting external grinding fluid; the abrasive dust generated during grinding of the grinding wheel can not be effectively removed, the abrasive dust can damage the surface of a machined workpiece, and the quality of the surface of the workpiece can not be effectively improved.

In summary, how to effectively supply the grinding fluid to the grinding area and instantly supply the grinding fluid to the grinding area during the process of grinding the optical glass by the diamond grinding wheel, and effectively remove the grinding dust generated during the grinding process of the grinding wheel to improve the surface quality of the workpiece has become an urgent problem to be solved.
