1、 Application of machine tools This machine adopts FANUC 0I numerical control and industrial control computer dual system, which is suitable for machining pistons with any shape of loading surface (such as ellipse plus eccentric circle, ellipse plus circle, circle plus eccentric circle, staggered ellipse loading surface, etc.). The computer can store the processing programs of various parts, and the selection is convenient. The software is easy to learn, easy to use, low requirements for operators. According to the product drawing, the original data of shape line and ellipse can be input to generate piston processing data. The Chinese character interface has online prompt and help function. The machining process is only one key operation. The system has the function of self diagnosis and alarm. The machine has the advantages of high power, good rigidity, novel and reasonable structure, beautiful appearance, convenient and flexible operation, and wide application. The dimension accuracy of the machined parts reaches it7, the surface roughness of aluminum alloy is less than or equal to Ra0.8 μ m, and that of cast iron and steel (280hb) is less than or equal to Ra1.6 μ M.
