Precision CNC machining is actually index-controlled machining. After programming the drawings to be processed into the program, the computer is connected to the CNC machining machine to program the CNC machining machine to complete the machining of precision parts.
First of all, before the CNC parts are processed, it is necessary to clearly understand the contents of the process, clearly know the parts, shapes, drawings and dimensions of the workpiece and know the processing contents of the next process.
Before processing the raw materials, the blank size should be measured to meet the requirements of the drawings; it must be carefully checked whether the placement is consistent with the programmed instructions; after the roughing of the machining process, the self-test should be carried out in time to adjust the data with errors in time. The self-test content is mainly the position size of the processing part. (1) Whether there is looseness in the processing of mechanical parts; (2) Whether the part processing technology is correct to the starting point; (3) Whether the size of the CNC part processing to the reference side (reference point) meets the requirements of the drawings; (4) CNC The positional size of the processing parts relative to each other. The roughened shape ruler is measured after the position size has been checked (except for the arc). The parts are finished after roughing and confirmed. Before the finishing, the shape and dimension of the drawing part are self-checked: the basic length and width dimensions of the processing part of the vertical surface are detected; the base point size marked on the drawing is measured on the processing part of the inclined surface. After completing the self-test of the parts and confirming that they are in conformity with the drawings and process requirements, the workpieces can be removed and sent to the inspector for special inspection. In the case of encountering precision cnc parts processing small batch parts processing, the first piece must be confirmed and qualified for batch processing.
The above is the essence of the precision CNC machining process, thank you! If you have any questions about precision CNC machining and precision parts processing, please call Jingzhixing: We will be happy to provide you with services!
