Detailed introduction to the process flow of CNC precision machining

CNC precision machining and CNC numerical control are not only different, but also very different.

First, from the point of view of the operation mode, the CNC numerical control equipment is controlled by the panel, and the operator can only work for three to four days after learning. The CNC engraving machine is operated by computer, which is very convenient to use. Basically, you can master it all once you learn it.

Second, from the programming point of view, the CNC numerical control equipment has cycle commands, while the engraving machine needs to be manually programmed.

Third, the processing speed of the engraving machine is faster than that of the digital machine tool, and the output is high.

Stamping precision cnc machining is actually index-controlled machining. After programming the drawings to be processed into the program, connect the computer to the cnc machining machine, and command the cnc machining machine to operate through programming to complete the precision parts. processing. CNC precision machining is mainly suitable for the processing of small batches and large batches of various types of spare parts. The precision of CNC machining parts is very high, so it serves the processing of precision parts in different industries. The following editor will introduce to you the process flow of CNC precision machining.

Before machining CNC parts, you must clearly see the content of the process flow, clearly know the parts, shapes, 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 blank size 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 completed, the self-check should be carried out in time, so as to adjust the data with errors in time. The main content of self-inspection is the position and size of the processing part.

1. Is there any looseness in the machining process of the mechanical 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 CNC precision machining positions. After checking the position dimension, measure the rough machined shape ruler (except arc).

Parts are finished after roughing confirmation. Before finishing, conduct self-inspection on the shape and size of the drawing part: check the basic length and width of the processing part of the vertical plane; measure the base point size marked on the drawing for the processing part of the inclined plane.

Complete the self-inspection of the parts and confirm that they conform to the drawings and process requirements before removing the workpiece and sending it to the inspector for special inspection. When encountering small batch processing of precision CNC parts, batch processing is required after the first part is confirmed to be qualified.

The above content is an introduction to the process flow of precision cnc machining. The CNC machining center machine tool itself has high precision and has unique advantages for the processing of high precision, complex and small batch parts; precision grinders belong to precision machining equipment One is mainly finishing, mainly for quenched parts processing; CNC lathes are also automated processing equipment, generally processing shafts, rods, and round parts, which are more advantageous for special precision requirements or small batch processing.
