Precision CNC parts processing process

Precision cnc machining is actually exponential control machining. After programming the drawings that need to be processed into the program, connect the computer to the cnc processing machine tool, and command the cnc processing machine tool to operate through programming to complete precision parts processing. Precision cnc processing is mainly suitable for small batches and large batches of various types of parts processing. The precision of cnc processing parts is very high, so it serves the processing of precision parts in different industries!

First of all, you must see the content of the process flow before CNC parts processing, 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 the raw material, measure whether the size of the blank meets the requirements of the drawing, and carefully check whether its placement is consistent with the programmed instructions.

The self-check should be carried out in time after the rough machining of the processing technology is completed, so that the data with errors can be adjusted in time.

The content of the self-check is mainly the position and size of the processing part.

(1) Whether there is any looseness during the processing of mechanical parts;

(2) Whether the machining process of the parts is correct to touch the starting point;

(3) Whether the dimension from the machining position of CNC parts to the reference edge (reference point) meets the requirements of the drawing;

(4) The size of the position between the CNC machining parts. After checking the position and size, the roughing shape ruler should be measured (except for the arc).

After the rough machining is confirmed, the parts will be finished. Perform self-inspection on the shape and size of the drawing parts before finishing: check the basic length and width dimensions of the processed parts of the vertical surface; measure the basic point size marked on the drawing for the processed parts of the inclined surface. After completing the self-inspection of the parts and confirming that it meets the drawing and process requirements, the workpiece can be removed and sent to the inspector for special inspection. In the case of small batch processing of precision cnc parts, batch processing is required after the first piece is confirmed qualified.
