machine tool industry is the foundation of modern industry, especially modern manufacturing industry, which occupies an important strategic position in the national economy.cooling and purification devices for machine tools have always been considered as accessories of machine tools and do not play a significant role.in fact, with the improvement of the degree of automation and the accuracy of the machine tool, the overall machine tool cooling purification device and other functional components put forward higher requirements, especially in the high precision, high efficiency, complex shape and difficult cutting material processing, the role is particularly prominent.
cooling and purification device is mainly cooling and purification of two major functions.cooling effect mainly prevents thermal deformation and burn during grinding process.thermal deformation and burn in grinding process is a very complicated problem.it is related to many conditions, such as: grinding wheel, processing technology, nozzle, etc.cooling and purification devices are also an important factor.grinders, especially powerful forming grinders, have a large amount of cutting and heat generation in the grinding process, so the cooling requirement is very high.due to the lack of definite experience in this area, burns are a common problem in the processing of hard-to-grind materials.the general treatment method is to improve the flow and head of the cooling water pump.for the analysis of the same type of foreign products, the motor parameters of the pump they chose were lower than ours, but there was no burn.it is necessary to verify the amount of cutting required for the corresponding flow and head of the pump motor and whether the water tank oil cooler is needed.purification refers to the use of coolant to remove iron filings and abrasive particles from the grinding area, while separating impurities from the coolant to prevent impurities from affecting the grinding quality.at present, the cooling water tank with large flow and high head is only filtered by single-layer paper.the grinding volume is large, the iron cutting and grinding wheel sａnd is also quite a lot, often appear the filter is not timely iron chip leakage from both sides such as the inside of the water tank.at the same time, more users report that the filter paper is used too fast, so it is necessary to add a primary filtration, such as primary precipitation or magnetic separation, before the paper filtration.of course, the parameters must match the tank itself.
other design details of the cooling purification device need to be considered and the design of some small functional components is also quite necessary.once the user found that a small flow of water tank coolant loss is very fast, every 3-4 days need to add water to the water tank.later, it was found that the coolant evaporated too fast, of course, most of it was lost in the grinding site, but for the water tank, the function does not affect the case as far as possible to seal, to prevent excessive evaporation of coolant and damage to the processing environment.some humanized designs need to be formed in long-term observation and accumulation.many users use water guns when cleaning machine tools.therefore, it is necessary to add a small pump at the back of the tank for the water gun.in addition, add some cleaning impurities inside the tank and add cleaning window, convenient to use after a period of time to clean the tank.
