The Process of Precision CNC Machining Parts

Precision CNC machining parts are actually exponential-controlled machining. First, program the drawings that need to be processed and write them into the program, then connect the computer to the CNC machining machine tool, and command the CNC machining machine tool to operate through programming to complete the precision part processing. Precision CNC machined parts are mainly suitable for small batches and various types of parts processing. CNC machining parts have very high precision, so they serve the precision parts processing in different industries.

1. Before CNC parts processing, you must know the content of the process, clearly understand the parts, shapes, drawings, and dimensions of the workpiece to be processed, and know the processing content of each process.

2. Before clamping the raw materials of precision CNC machining parts, first measure whether the blank size meets the requirements of the drawing, and carefully check whether the placement is consistent with the programmed instructions.

3. After the rough machining of the processing technology is completed, the self-check should be carried out in time, and the data with errors should be adjusted in time.

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

(1) Whether there is any looseness in the processing of mechanical parts.

(2) Whether the part processing technology correctly touches 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 position and size of precision CNC machined parts. After checking the position and size, the roughing shape ruler should be measured (except for arcs).

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 plane; measure the basic point size marked on the drawing for the processed parts of the inclined plane. After completing the self-inspection of the parts and confirming that it is in compliance with the drawings 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 machined parts, batch processing is required after the first piece is confirmed qualified.
