Nc special machine tool of working principle

The earliest modular machine tools were made in the United States for processing auto parts. According to the function, the general parts can be divided into five categories: power parts, supporting parts, conveying parts, control parts and auxiliary parts. The power unit is the part that provides the main movement and feed movement for the modular machine tool. The main power box, cutting head and power slide. The supporting parts are the parts used to install the power sliding table, the cutting head with the feeding mechanism or the fixture, etc., including the side base, the middle base, the bracket, the adjustable bracket, the column and the column base, etc. The conveying parts are the parts used to transport the workpiece or headstock to the processing station, mainly including indexing rotary table, ring indexing rotary table, indexing drum wheel and reciprocating moving table. Control parts are the parts used to control the automatic working cycle of machine tools, including hydraulic stations, electrical cabinets and control desks. The auxiliary parts are lubricating device, cooling device and chip removal device, etc. In order to make the modular machine tool can be used in small and medium batch production, it is often necessary to apply the modular technology, the structure and process of similar parts in a modular machine tool processing, in order to improve the utilization rate of the machine tool. In order to simplify the structure and shorten the production time, more speed regulating motors and ball screw will be adopted in the future development of modular machine tools. Digital control system and headstock, fixture automatic replacement system to improve the process adjustable; And the incorporation of flexible manufacturing systems.
