In the world of machining, CNC operations, and heavy industrial equipment, coolant management is one of the most crucial factors that affect tool life, product finish, and overall productivity. A coolant tank is a specialized storage and filtration system designed to hold, circulate, and manage coolant fluid used in machine tools. But coolant tanks are only one part of a much larger discipline — general fabrication — which includes designing, cutting, bending, welding, and assembling sheet metal and steel structures. Fabrication is the process by which raw materials are turned into functional components like tanks, guards, ducting, frames, or machine covers. This guide covers everything you need to know about coolant tanks and general fabrication: their construction, functions, design considerations, materials used, manufacturing process, maintenance, and industry applications.
