How often to change tool of spindle
The panel furniture production line is widely used by furniture companies. In the long-term use process, the tools will inevitably wear out. If the replacement is not timely, the production efficiency and quality will be greatly affected, but when the replacement is made, the maximum value of the tool can be exerted. It requires us to have a reasonable grasp of tool wear.
1, according to the tool life table (based on the number of workpieces), some high-end equipment manufacturing or single-product mass production enterprises use it to guide production, this method is suitable for processing expensive aerospace, steam turbines, automotive key components such as engines, etc. manufacturer.
2. Look at the tool. When the rake face wears and cuts the plastic material, the chip and the rake face are in contact with each other to form the crater wear. When the flank wear wears the brittle material, the contact length between the chip and the rake face is short, and the blunt round of the opposite edge causes the flank face to wear a lot. When the boundary wears the steel material, the main cutting edge is close to the workpiece skin and the minor cutting edge. Grinding deeper grooves near the flank on the tip of the tool.
3. look at the processing, if the processing process, the intermittent random Mars, indicating that the tool has worn, can be changed according to the average life of the tool.
4. Look at the color and shape of the iron filings. The color of the iron filings changes, indicating that the processing temperature has changed, which may be the wear of the cutter. Look at the shape of the iron filings, the jagged edges on both sides of the iron filings, the iron filings are not curled properly, and the iron filings become finer. These phenomena are the basis for the determination of tool wear. Looking at the surface of the workpiece, there are bright traces, but there is no big change in the roughness and size. This is actually the tool has worn out.
5. Listening to the sound, the processing vibration is intensified, and abnormal noise will occur when the tool is not fast. Always pay attention to avoid "knife" and cause the workpiece to be scrapped. If the workpiece is severely burred when the tool is cut out, the roughness is reduced, and the workpiece size is changed, which is also the criterion for determining the tool wear.
These are the most common forms of tool wear in the panel furniture production line. However, due to the different materials used by customers in daily processing and production, the wear patterns of the tools are also different. These require customers to pay attention to observation and summary, and the time is long. Just understand how to judge the degree of tool wear.
