<p>In the machining industry, CNC machining is actually exponentially controlled machining. After programming the drawings to be processed as a program, the computer is connected to the cnc processing machine tool, and the cnc processing machine tool is operated by programming commands to complete the processing of precision parts. cnc processing is mainly suitable for small batch and large batch processing of various parts. <a href="https://www.qyprecision.com" rel="noopener noreferrer" target="_blank"><a href="https://www.qyprecision.com" target="_blank">cnc parts</a></a> processing has very high processing accuracy, so it can be used for precision parts processing in different industries. The following small series introduces you to the machining process of cnc parts of precision machinery.</p><p><br></p><p>First, before processing cnc parts, you need to clearly see the content of the process flow, and you need to clearly know the parts, shape and size of the workpiece to be processed and the processing content of the next process.</p><p><br></p><p>Before clamping the raw material, measure whether the size of the blank meets the requirements of the drawing, and carefully check whether its position is consistent with the programming instructions.</p><p><br></p><p>After the roughing of the machining process is completed, self-inspection should be carried out in time to adjust the error data in time. The content of the self-check is mainly the position and size of the processed parts.</p><p><br></p><p>1. Is there any looseness in the processing of mechanical parts;</p><p><br></p><p>2. Whether the part processing technology is correct;</p><p><br></p><p>3. Whether the dimensions from the parts processed by cnc parts to the reference edge (reference point) meet the requirements of the drawing;</p><p><br></p><p>4. The position and size of cnc parts processing. After checking the position and size, measure the rough shape ruler (except the arc).</p><p><br></p><p>The part is completed after rough machining confirmation. Before finishing, check the shape and size of the drawing part: check the basic length and width of the vertical surface processing part; measure the size of the base point of the inclined plane processing part marked on the drawing. Complete the self-inspection of the parts, confirm that they meet the drawings and process requirements, and then remove the workpiece and send it to the inspector for special inspection. When cnc parts are processed in small batches, they need to be processed in batches after the first piece is confirmed to be qualified.</p>
