Yu Botou are SK300 valve special machine tools, valves, three milling machines, CNC machine tools Valve cast steel valves Machine refers to a digital system control machine tools, is an automated process control system of the machine is equipped with working valves. The control system is capable of handling a control logic codes or other symbols Directive procedures, and decoded code of the digital representation of the information carrier input by the numerical control device. Issued by the arithmetic processing of various control signals to control the operation of the machine, according to the shape and size requirements of the drawings, parts machined automatically by the numerical control device; a typical mechatronic products. CNC machine control unit, CNC machine operation and monitoring of all completed in the CNC unit, which is the brain of CNC machine tools. Compared with the general machine tools, CNC machine tools Valve has the following characteristics: 1, high precision, stable machining quality; 2, can be multi-axis linkage, can process complex shape parts; 3, machining parts changes, generally only need to change the NC program can save production lead time; 4, high precision machine itself, rigidity, choose the amount of favorable processing, high productivity (usually 3-5 times the normal machine); 5, high degree of automation machine, It can reduce labor intensity;
