Description

Method for removing burr of a spray nozzle and a spray nozzle manufactured using the same The present invention relates to a method for removing burrs from a spray nozzle and a spray nozzle manufactured thereby, and more specifically, to a method for removing burrs from a spray nozzle and a spray nozzle manufactured thereby. Generally, when performing mechanical processing such as cutting, shaping, press processing, die casting, and injection molding using CNC lathes, machining centers, milling machines, and drilling machines, not only are burrs generated on the processed area, but the surface is also rough and uneven. At this time, while burrs can be easily removed manually when the processed workpiece is large, there is a problem in that it is difficult to remove burrs manually when the workpiece is small. However, since these burr removal devices use permanent magnets, the strength of the magnetic field acting inside the container cannot be adjusted, so burr removal cannot be controlled according to the material of the product. In other words, because the distance between the container and the magnet is short, the magnetic field is strong. When abrasives and soft workpieces are introduced into the container under these conditions, the abrasives graze the workpiece forcefully when removing burrs, causing damage to the workpiece's outer surface. Therefore, abrasives that are affected by magnetic fields are manufactured and used according to their type. However, there was a problem in that maintenance costs increased because various types of abrasives had to be kept on hand, classified into ferromagnetic and weakly magnetic materials depending on the workpiece. Furthermore, there was the inconvenience of having to select and insert the appropriate abrasive depending on the material of the workpiece. In addition, because the distance between the container and the magnet was short, the abrasive had a strong tendency to adhere to the magnet, making it difficult to detach the container. In addition, heat-sensitive workpieces sometimes experienced deformation in shape and color during the burr removal process, which significantly limited their use. Meanwhile, conventional burr removal devices had a problem in that they could not perform burr removal work for a long time because components such as motors located inside the body would heat up significantly when performing burr removal work for a long time, which not only shortened their lifespan but also caused frequent breakdowns. Recently, as particle control has become stricter for spray nozzles used in semiconductor nanoprocesses, particle levels within the nozzles have also begun to be managed. Previously, after installing the nozzles in the equipment, particles in all flow paths within the equipment were flushed out for nearly a month to remove foreign matter, but despite this treatment, the situation is such that foreign matter is not being controlled. In addition, if very small burrs adhered to the cutting surface of the spray nozzle and the nozzle was sprayed for a long period, these fine burrs could detach, potentially causing quality issues. In particular, since the spray nozzle material is made of a resin material that is easily deformed by external impact, there were also problems such as deformation, denting, cracking, deformation of spray performance, and dimensional deformation occurring continuously due to appropriate abrasive force.
