In the mechanical parts processing industry, the unreasonable processing technology of precision parts will directly affect the quality. How to ensure precision parts processing, reasonable processing technology is closely related. Let’s take a look at the solution to the tool receiving trace during the processing of aluminum CNC parts:
- Finish machining and rough machining shall be separated, and an appropriate amount of finish machining allowance shall be reserved: in order to ensure that the appearance and size of the product meet the standard value, usually there will be a knife path on the part surface before finish machining, so the allowance after rough machining should be guaranteed to be between 0.05mm ~ 0.15mm.
- Aluminum material is light and belongs to one of the easy cutting materials. Programming command cutting command, the dialog box will also change due to different programming software, but the cutting tolerance is an indispensable setting parameter in programming, and the size of the tolerance also directly affects the accuracy and appearance of the product.
- In the cutting process, optimize the overlap of advance and retreat tools: after optimizing the program, although there will be overlapping traces at the advance and retreat tools, the embossing and tool receiving marks can be eliminated.
- It can improve the size and appearance. Selective feed / retract: extend the feed / retract line so that neither feed nor retract will contact the workpiece, making the machining surface smoother.
- Finally, check the accuracy of the machine tool, which needs regular maintenance. Using the platform bottom plate for a long time will damage and the machine tool platform will also produce errors.
The above are the solutions to the precision CNC machining process.
