CNC precision parts processing, refers to the production and processing drawings indicated on the high precision, need to use precision parts processing machinery and equipment to complete. Mechanical processing manufacturers ultra-precision machining machinery and equipment are: CNC machining center, precision surface grinding machine and CNC machine tools, etc.; CNC machining center machine tool itself high precision, high precision, more complex class, small batch mechanical parts processing has technical advantages; precision surface grinding machine is classified as one of the precision parts processing machinery and equipment, usually finishing, mainly for quenching treatment of mechanical parts processing;. CNC machine tools are also automated production machinery and equipment, usually shaft, rod, round type mechanical parts processing, for special precision requirements or small batch mechanical parts processing is relatively more advantageous.
CNC machining process and basic working principle.
1、Distinction of process flow and work steps; determination of tool setting point and machining center tool change point.
2、The route of production processing is determined; the choice of processing method and processing scheme is determined.
3, the rational use of machine tools, the number of workpiece accuracy using different models.
4, the installation of parts and the choice of fixtures.
5, the selection of tools and the determination of the cutting dosage.
6, CNC machining parts processability analysis, reasonable processing technology.
