Businesses in the "other machine tools" category supply, manufacture, maintain or repair machine tools and related equipment that does not fit a more specific directory category. These tools are used in workshops and factories to cut, shape, drill, grind, finish or otherwise process materials, particularly metals and plastics. Depending on the business, the range may include specialist cutting and forming machines, tool-and-cutter grinders, presses, saws, honing equipment, machine tool accessories and replacement parts. Customers may be able to obtain new or used machinery, arrange installation and commissioning, or request servicing, repairs and refurbishment. Some suppliers also provide tooling, work-holding equipment, measuring instruments, control systems and operator training. The type and scale of equipment vary, from manually operated machines for small workshops to computer-controlled production equipment.
