Abstract

The invention provides a nano layer lubrication diamond grinding wheel grinding method based on a shock wave cavitation effect. The method is characterized in that after an air pressure adjusting valve is opened, shock waves generated by an accelerating tube push nano particles to move forwards, and then the nano particles are accelerated by a small laval tube to obtain a high initial speed; meanwhile, a wave source of a shock wave accelerating module generates high-frequency and high-strength shock waves to impact the nano particles with the initial speed, so that the nano particles are continuously accelerated downwards in the axial direction of a large laval tube until the nano particles are embedded into the surface of a grinding wheel at the highest speed to form a nano layer; the other wave source is used for cleaning impurities on the surface of the grinding wheel; and in the machining process, the nano particles of the nano layer are autonomously released in a grinding core area, so that self-lubricating cooling in a grinding area is achieved. The method greatly enhances the lubricating cooling effect, and also conforms to the concept of green development.

Description

technical field [0001] The invention relates to the technical field of lubricating and cooling in grinding, in particular pointing out a nano-layer lubricated diamond grinding wheel grinding method based on the shock wave cavitation effect. Background technique [0002] Grinding is widely used in the current processing industry because of its high processing precision and strong adaptability to workpiece materials. However, the energy consumed by grinding to remove a unit volume of material is far greater than that of other commonly used processing forms Nearly 90% of the consumed energy will gather in the grinding area in the form of grinding heat, which will lead to high temperature and high pressure in the grinding area, which will affect the service life of the abrasive tool and reduce the surface accuracy of the workpiece. [0003] The traditional pouring lubrication adopts the method of continuous irrigation of a large amount of grinding fluid to the grinding area for ...
