The advantages of the horizontal arm coordinate measuring machines (CMMs) from Hexagon Manufacturing Intelligence are particularly apparent when inspecting sheet metal parts in the car industry, or other large-volume components in the aerospace, ship, defense, appliance, machinery and railway industries. Their open structure permits direct access to the workpiece and therefore significantly eases loading and unloading. Horizontal CMMs can also be integrated as a component of an automated production line such as automotive body-in-white.
