Machine tools (English name: machine tool) is the main turning tool on the rotating workpiece turning processing equipment, generally divided into metal cutting machine tools, forging machine tools and woodworking machine tools. The machine tool is mainly composed of support parts, speed change mechanism, feed mechanism, spindle box, lubrication system, etc.. Modern machinery manufacturing in the processing of mechanical parts in many ways: in addition to cutting, there are casting, forging, welding, stamping, extrusion, etc., but all of the higher precision requirements and surface roughness requirements of the finer parts, generally need to be in the machine tool with the method of cutting for the final processing. Machine tools play a major role in the modernization of the national economy.
Numerical control machine tool is the abbreviation of digital control machine tool, is a kind of automatic machine tool equipped with program control system. The control system is able to logically process the program with control code or other symbolic instructions, and decode it, so that the machine tool action and processing parts of the control unit, CNC machine tool operation and monitoring are all completed in this CNC unit, which is the brain of the CNC machine tool. High machining accuracy, stable processing quality; can carry out multi-coordinate linkage, can process complex shaped parts; processing parts change, generally only need to change the CNC program, can save the production preparation time; machine tool itself, high precision, high rigidity, you can choose the amount of favorable machining, high productivity (generally for ordinary machine tools, 3 ~ 5 times); machine tool automation is high, you can reduce the intensity of labor; the operator quality requirements are high, the operator quality is high. Operator's quality requirements are high, the technical requirements of maintenance personnel is higher. CNC machine tools are generally composed of the following parts: host, is the main body of the CNC machine tool, including the machine body, column, spindle, feed mechanism and other mechanical components. It is used to complete a variety of mechanical components of cutting processing.
