Detailed introduction to the process flow of CNC precision machining

Stamping CNC precision machining is actually index-controlled machining. First, the drawings that need to be processed are programmed and calendared, and then the computer is continued to the CNC machining machine. Programming to command CNC machine tools to operate, to achieve precision parts processing. CNC precision machining is mainly suitable for the processing of small and large quantities of various types of spare parts. The precision of CNC machining parts is very high, so it is not suitable for precision parts processing in different industries. The editor below will introduce to you the process flow of CNC precision machining.

First of all, before CNC parts are processed, you must clearly see the content of the process flow, clearly know the parts, styles, drawings and dimensions of the workpiece to be processed, and know the processing content of the next process.

Before processing raw materials and clamping, you should measure whether the size of the blank meets the requirements of the drawing, and you must carefully check whether its placement is consistent with the programmed instructions.

After the rough machining of the machining process is realized, a self-inspection should be carried out in time to adjust the data with errors in time. The content of the self-inspection is the position and size of the processing part.

1. Is there any looseness in the machining process of the machine parts;

2. Is the machining process of the parts correct? Whether the size of the reference edge (reference point) meets the requirements of the drawing;

4. The position size of the CNC machining parts. After checking the position size, measure the rough-processed pattern ruler (except arc).

The part was roughed and confirmed to be out of date for finishing. Before finishing, conduct self-inspection on the style and size of the drawing part: check the basic length and width of the vertical plane processing part; measure the base point size marked on the drawing for the inclined plane processing part.

Realize the self-inspection of the parts, and only after confirming that they conform to the drawings and process requirements, the workpiece can be removed and sent to the inspector for special inspection. When encountering a small number of precision CNC parts processing, batch processing is required after the first piece is confirmed to be qualified.

The above content is an introduction to the process flow of CNC precision machining. The CNC machining intermediate machine tool itself has high precision, and it has a unique advantage in the processing of high precision, complex types, and a small number of parts; precision grinding machines belong to precision machining One of the equipments is mainly finishing, and it is important to process the quenched parts; CNC lathes are also automatic processing equipment, and the processing of ordinary shafts, rods, and round parts is relatively advantageous for the processing of special precision requirements or a small number of parts.
