Is it reasonable that the tool grinding oil input accounts for less than 0.1% of the equipment?
February 15, 2022
According to the survey statistics, the facts cannot be ignored. Most companies invest 100,000 US dollars in equipment introduction and 10,000 US dollars in the purchase of spare parts such as grinding wheels, but the investment in grinding oil is less than 100 US dollars, and 40-60% of the grinding problems are the supply of grinding oil. Caused by insufficient fluid! However, grinding oil in tool production is the link between the grinding wheel and the workpiece; even with the best equipment, it is difficult to machine tools that meet the requirements without good grinding oil.
The way and influence of tool temperature and nozzle flow in grinding Temperature of the machining area during tool grinding: During grinding, about 65-90% of the heat is transferred to the workpiece, and less than 10% of the heat is taken away by the grinding chips; the heat often forms a local high temperature on the surface. Local high temperature will cause surface thermal damage (surface oxidation, burns, residual stress and cracks), reduced workpiece machining accuracy, and reduced grinding wheel service life.
Nozzle flow and method during tool grinding: Unreasonable nozzle liquid supply method will cause Insufficient fluid supply in the grinding area; most of the grinding fluid does not enter the machining area Unstable nozzle position that can change when exposed to high pressure or improperly maintained. Unreasonable nozzle liquid supply method will cause A lot of smoke is generated, affecting the working environment The temperature varies greatly from hot to cold. The temperature of the grinding zone is easy to rise, which directly affects the durability of the grinding wheel and the surface quality of the workpiece.
Tool grinding cooling: If the design of the grinding fluid supply method is unreasonable, the proportion of heat transferred to the workpiece is about 3 times that of the grinding fluid.
