Profile: Alfred McAlpine Water is a provider of CNC milling and turning service. Our CNC milling service uses computer programming to control the motion of a cutting tool, which develops the profile of an external or internal surface to a material mounted on a milling machine. This allows the robotic production of simple mass-produced items, or more complex items for aerospace or medical equipment. Our CNC turning involves the generation of metal or plastic linear profiles using a center lathe.
