Automotive parts processing parts

The sequence of steps for CNC machining of automotive parts begins with a clear understanding of the process content included in the machining drawings, including the position, shape, size, and machining content of the next process, before CNC machining. Write the necessary drawings into the program, then connect the computer to the CNC lathe and run the CNC machine according to the programming instructions for rapid prototyping of parts.

Self inspection should be carried out promptly after rough machining to facilitate timely adjustment of data with deviations. After rough machining, the parts are subjected to precision machining. After precision machining, workers should check the shape and size of the machining position. After self inspection of the workpiece and confirmation of compliance with the drawings and process requirements, the workpiece is removed and sent to the inspector for special inspection. When small batch processing is necessary, the first prototype model must be confirmed to meet the standards before batch processing can be carried out.

There are many areas to pay attention to in the entire processing process, otherwise it is easy to cause part damage. CNC machining manufacturers have summarized several things worth noting:

1. Whether the machining process of the parts correctly touches the starting point;

2. Whether there is looseness during the processing of mechanical parts;

3. The position and size between the processing surfaces. Check the basic width dimension of the vertical plane and the base point dimension indicated on the measurement drawing of the slope. Measure the rough machining shape ruler after checking the position dimensions (excluding arcs);

4. Direction scale of the processing surface. Whether the dimensions from the machining surface of the part to the standard edge (reference point) comply with the drawing specifications;

Before clamping the workpiece, it is necessary to carefully check whether the size of the raw material meets the requirements of the drawing.
