As one of the main machines in the panel furniture production line, the processing effect of the CNC Router directly affects the processing effect of the finished product. During the long-term use of the CNC Router, the tool will inevitably wear out. Failure to replace it in time will affect production efficiency and processing accuracy. However, when to replace it, the value of the tool can be fully utilized, which requires us to be able to reasonably grasp the tool wear.
1. According to the tool life table (based on the number of workpieces processed), some equipment manufacturing industries or single-product batch production companies use it to guide production. This method is suitable for aerospace, steam turbines, and automobile key components such as engines, etc., which have expensive workpieces.
2. Look at the tool. When the front cutting face is worn and cutting plastic materials, the chips and the front cutting face contact each other, mainly forming crescent wear. When the back cutting face is worn and cutting brittle materials, the contact length between the chips and the front cutting face is short, and the relative bluntness of the blade causes greater wear on the back cutting face. When cutting steel materials with boundary wear, the main cutting edge is close to the outer skin of the workpiece and the secondary cutting edge is close to the tip of the blade. Deep grooves are often ground on the back cutting face.
3. Look at the processing. If intermittent and irregular sparks emerge during the processing, it means that the tool has been worn. The tool can be replaced in time according to the average life of the tool.
4. Look at the color and shape of the sawdust. If the color of the sawdust changes, it means that the processing temperature has changed, which may be tool wear. Look at the shape of the sawdust. The sawdust is serrated on both sides, the sawdust is abnormally curled, and the sawdust becomes more fragmented. These phenomena are the basis for judging tool wear. Look at the surface of the workpiece. There are bright marks, but the roughness and size have not changed much. This is actually the tool has been worn.
5. Listen to the sound. The processing vibration is intensified, and abnormal noise will be generated when the tool is not fast. Always pay attention to avoid "stabbing the knife" and causing the workpiece to be scrapped. If the workpiece has serious burrs when the tool is cut out, the roughness decreases, the workpiece size changes, and other obvious phenomena are also the criteria for judging tool wear.
The above are several common forms of tool wear for CNC Routers, but because the materials used by customers in daily processing and production are different, the forms of tool wear are also different. This requires customers to pay more attention to the use of the tool and do daily maintenance.
