Machine tool shops require a higher level of durability from their rugged computers and displays, as compared to the technology needs of production and manufacturing facilities. They are using machine tools to cut, bore, grind, shear or alter the shape of rigid materials, typically metals.

The rugged HMIs are placed close to the machine tools to allow for operator control and precision. By placing them so close, they not only are impacted by the gyrations of the machine tools, but are also usually splashed on by the liquid (i.e. oil) used to lubricate the metal and allow the machine tool to manipulate the material more effectively.

Machine tooling facilities typically look for NEMA4X, IP65 or IP66 rated rugged displays and computers that ensures the industrial technology has been thoroughly tested and approved that it will perform well in these given environments with liquid splashing and vibrations, jolts.
