On the lathe, the use of the linear motion of the workpiece rotation and tool or curve motion to change the shape and size of the blank, processing it to conform to the requirements of the drawings. Ordinary machine tool is more and more difficult to meet the needs of the machining precision parts. At the same time, because of the improvement of production, the price of the CNC machine tool are falling. CNC precision parts processing mainly has the ultra-precision turning, mirror grinding and grinding etc. CNC precision parts processing is the first premise of its accurate process benchmark, the benchmark on the mechanical drawings are in capital letters A, B, C, D, etc with A specific symbol with ring. When the benchmark symbols on the surface and the extension of line or the plane size limit, said on the surface as a benchmark. When the benchmark symbols on the dimension line, said in the dimensioning of the center line of the entity as a benchmark. As you mentioned earlier process precision is a more general point of view. Assembly benchmark, is used to determine when the assembly parts location precision in the component or product. Measurement benchmark, refers to the parts inspection, the size and location of the machined surface to be measured. Locating datum, refers to the process, the workpiece positioning in machine or jig with the benchmark. CNC precision parts processing technology benchmark is the prerequisite of produce quality parts. Given yuan is a commitment to the development of coating equipment and related equipment, manufacturing equipment and accessories manufacturing of high-tech enterprises, and is mainly engaged in coating production of spare parts, CNC precision parts processing, batch parts processing, tel: 0086 - 574 - 55224980
