In CNC machining, tool marks (also called cutting marks) may sometimes occur. This situation is mainly because the tool makes a feeding movement during the machining process, but the interface is not tight enough, resulting in a certain vibration during cutting, forming tool joint marks. This will have a certain impact on the quality and aesthetics of the product. So how to deal with knife marks?
First, KFX can improve this situation by modifying the processing parameters. We can reduce the cutting speed, increase the cutting depth, reduce the feed amount, etc. to reduce the number and time of contact between the tool and the workpiece, thereby avoiding the occurrence of tool marks. Of course, this method also needs to be fine-tuned according to the specific situation, because different materials, tools and workpieces may have different needs.
Secondly, KFX can reduce the occurrence of tool marks by replacing tools. Because if the quality or wear of the tool itself is not good enough, some unexpected problems will occur during processing, such as the generation of tool marks. Therefore, we need to choose high-quality tools and check and replace them regularly.
Third, we can process the workpiece before processing. In this regard, we can take some simple methods, such as polishing or grinding to remove defects such as unevenness, bulges or depressions that may exist on the surface of the workpiece, thereby avoiding machining errors caused by unevenness and reducing the gap between the tool and the workpiece. The number of contacts reduces the appearance of knife marks.
Finally, on the premise of ensuring the processing quality, KFX can use surface coating to cover up the cutting marks, thereby improving the appearance quality of the product. This method can be applied according to specific processes and requirements, and generally requires full consultation and communication with the customer or production department in advance.
In short, tool marks are a common problem for CNC machining, but as long as we take appropriate methods to deal with it, we can avoid affecting the processing quality and product aesthetics, and at the same time, we can improve production efficiency and economy. benefit.
