Stamping precisionDense cnc processingIn fact, it is index-controlled processing. After programming the drawings 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. The following editor will introduce the technological process of precision CNC machining.
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-inspection 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 part processing technology correctly touches the starting point;
3. Whether the size from the machining position of the CNC part to the reference edge (reference point) meets the requirements of the drawing;
4. The position and size of the cnc processing 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 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 parts, batch processing is required after the first piece is confirmed qualified.
The above content is an introduction to the technological process of precision CNC machining. CNC machining center machine tools have high precision and unique advantages for high precision, complex and small batch parts processing; precision grinders are one of the precision machining equipment, mainly for finishing , Mainly for the processing of quenched parts; CNC lathes are also automatic processing equipment, general shaft, rod, round parts processing, special precision requirements or small batch parts processing has advantages.
