Metalworking



Metalworking is any process used to shape, form, cut, or machine a metal workpiece. Metalworking lubricants, coolants, and fluids are specialized coatings and carriers for metal forming, metal cutting, lapping, polishing, and grinding applications.

· Metal forming is a process used to plastically deform a workpiece. In order to achieve the desired shape or geometry, a force must be applied that exceeds the material's yield strength. Metal forming oils, greases, and fluids dissipate heat, lubricate the working surface, and prevent localized strain that would otherwise cause damaging effects both to the tool and finished product.

· Metal cutting is a machining operation used to remove material and dissect workpieces. The primary function of the cutting fluid differs dependent on the cutting speed. At low speed the fluid acts as a lubricant prevent galling, friction welds, or other friction-induced wear at the cutting surface. At high speeds the fluid primarily acts as a coolant, preventing thermal deformation. Cutting fluids also function to remove cuttings, inhibit corrosion, and improve the cutting surface finish.

· Lapping, polishing, and grinding are metalworking operations used to improve the surface of a workpiece. In lapping or polishing compounds, fluids or oils are used to carry abrasive powders. In grinding applications the main function of metal working lubricants, coolants, and fluids is to perform workpiece cooling.
