Process Flow of Precision CNC Machining

Mar. 12, 2020

Stamping precision CNC machining is actually index controlled machining. After programming the drawings to be processed into the program, the computer is connected to the CNC machining machine, and the CNC machining machine is commanded by programming to complete the precision part machining. Precision CNC processing is mainly suitable for small batch and large batch processing of various types of spare parts. CNC machining parts have very high precision, so they serve precision parts processing in different industries. The Brass Accessories CNC Turning Exporter introduces the process of precision CNC machining.


First of all, before CNC Parts Processing, it is necessary to read the content of the process flow clearly, know the parts to be processed, the shape, the dimensions of the drawings, and know the processing content of the next steps.


Before the processing of raw materials, the size of the blank should be measured to meet the requirements of the drawing. It must be carefully checked whether the placement is consistent with the programmed instructions.


After the rough processing of the processing technology is completed, a self-inspection should be performed in time to adjust the error data in a timely manner. The content of the self-test is mainly the position and size of the processing part.


1.Is there any looseness during the machining of mechanical parts?

2.Whether the part processing technology correctly touches the starting point;

3.Whether the size of the CNC machined part to the reference edge (reference point) meets the requirements of the drawing;

4. Position and size of CNC Machining parts. After checking the size of the position, measure the roughened shape ruler (except for arcs).

After roughing confirmation, the part is finished. Self-inspection of the shape and size of the drawing part before finishing: the basic length and width of the processing part on the vertical plane is measured; the base point size of the drawing is measured on the processing part of the bevel.


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


The above 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 high precision, complex, and small batch parts processing. Precision grinding machines are one of precision machining equipment, mainly precision, mainly for hardened parts processing; CNC lathes are also automated processing equipment, general shaft, rod, round type parts processing, special precision requirements or small batch parts processing advantages.
