Lubrication equipment manufacturing refers to the production of devices designed to supply lubricants (oil, grease) to the sliding and rotating parts of industrial machinery, automobiles, construction machinery, and other equipment, with the aim of reducing friction and wear, cooling, preventing rust, and sealing. Pumps, distribution valves, lubricators, filters, and piping are key products, and they play an indispensable role in extending the lifespan and ensuring stable operation of equipment across a wide range of industrial sectors, including machine tools, robots, wind power generation, steelmaking facilities, and food machinery. As high-precision fluid control is required, precision machining (lathes, milling machines, machining centers), grinding, and honing are frequently employed for component manufacturing. Furthermore, to improve corrosion resistance and durability, surface treatment and heat treatment are also crucial processes, and it is common to manufacture rough shapes by casting or forging, followed by finishing with machining.
