In order to ensure the processing quality of CNC centering machine processing factory parts and reasonable application of equipment, should be in the premise of the part drawing processability analysis, reasonable development of processing procedures. Without destroying the stiffness of the part, the bore should be divided into three stages before machining: roughing, semi-finishing and finishing. Determine whether there is a spindle, and also determine the sub-axis clamping position. In the actual selection, the centering machine processing products should be based on the accuracy and surface roughness of the parts, materials, structure shape, specifications and other factors using the appropriate processing methods and general in accordance with the first coarse then fine, first far then near the internal and external cross, the base surface priority and other principles, the processing process route is divided and allocated.


According to the above analysis, the tool is selected according to the nature of the material based on the principles of durability, wear resistance, and ease of chip breaking. Determination of spindle speed, feed and actual cutting parameters, etc., based on specific machining experience and tool application reference data.


Programming, after carrying out the first three steps, in some mathematical processing of the coordinates, you will be able to program. First write the spindle program, make sure it is correct, then write the sub axis program, the heart machine program requires more attention because the control axis, the tool, can be simultaneously eccentric rotary power tool and rotary tool, eccentric rotary power tool and power longitudinal cutting tool processing at the same time, sub axis rotary tool and spindle external I.D. tool processing at the same time, spindle C axis processing, main and sub axis synchronous movement rotation, main and sub axis rigid tapping, main and The main and secondary axes are compound controlled, and the main and secondary axes drill eccentric holes. Precision centering machine processing in the programming to understand the more difficult, more comprehensive provisions.
