Process and equipment for grinding nanometer fluid

Abstract

The invention belongs to a method and a device for mechanical grinding, namely a process and equipment for grinding nanometer fluid. The nanometer fluid grinding process comprises that nanometer-grade solid containing powder is supplied to a grinding area as a cooling lubrication medium in a grinding process. The equipment is characterized in that: the equipment comprises a lubricant storage tank, a water storage tank, a nanometer-grade powder storage tank and a high pressure air pump, which are arranged on a machine frame; and various mediums are mixed with the high pressure air, the mixture enters an atomizing chamber for mixing atomization and is conveyed to the grinding processing area by a hose and a spray head. Because the coefficient of thermal conductivity of the nanometer powder is high, the nanometer fluid can bring away a large amount of grinding heat when passing the high-temperature area, so that the cooling property of the grinding medium is enhanced, and the defect of the poor cooling effect of the micro lubrication is overcome; and simultaneously, because the weight of the nanometer powder is light, the characteristics and the advantages of the micro lubrication are maintained, the active effects of high processing quality, low cost and no pollution are achieved, and the method becomes the fourth generation lubrication cooling grinding process after wet processing, dry processing and micro lubrication.

Description

technical field [0001] The invention belongs to a mechanical grinding method and device, in particular to a nano fluid grinding process and equipment. Background technique [0002] Mechanical grinding includes two processes: free abrasive processing using abrasives and bonded abrasive processing using grinding wheels. Generally speaking, free abrasive processing is a smoothing process that uses free abrasive particles to remove the surface of the workpiece by scratching, and consolidated abrasive processing is a finishing process that uses sharp abrasive wheels to remove excess parts of the workpiece. Grinding technology is the most effective and widely used basic technology for precision machining and ultra-precision machining in modern machinery manufacturing. The data show that the amount of grinding accounts for about 30%-40% of the total machining. The characteristics of grinding processing determine that it consumes much more energy than other processing methods to r...

AI Technical Summary

Problems solved by technology

However, this processing method has the following defects: (1) The friction coefficient between the grinding wheel and the workpiece increases, which increases the friction force and causes serious wear of the grinding wheel

(2) A lot of heat is generated, the workpiece is deformed by heat, and it is easy to burn the processed surface

However, studies have shown that the cooling effect of high-pressure airflow and micro-water droplets is still very limited, which often cannot meet the needs of processing, and the processing effect of workpieces is worse than that of traditional processing modes, indicating that micro-quantity lubrication technology needs further improvement
