The following is the answer to how to solve the problem of tool sticking in Aluminum Product Processing, divided into four natural paragraphs:
1. Choose the right tool
In Aluminum Product Processing, the choice of tool is crucial. To solve the problem of tool sticking, tool materials suitable for aluminum processing, such as carbide tools, should be preferred. Carbide has high hardness and wear resistance, and can resist the adhesion of aluminum materials. At the same time, the geometry of the tool is also critical. Larger rake and back angles can reduce cutting forces and reduce the generation of cutting heat, thereby reducing the possibility of tool sticking. Sharp blades can better cut aluminum materials, reduce the friction between the tool and the workpiece, and avoid the occurrence of tool sticking.
2. Optimize cutting parameters
Reasonable cutting parameters can effectively reduce the occurrence of tool sticking. First, the cutting speed can be appropriately reduced. Excessive cutting speed will generate a lot of cutting heat, making aluminum materials more likely to adhere to the tool. Reducing the cutting speed can reduce the generation of heat and reduce the friction coefficient between the tool and the workpiece. Secondly, increase the feed rate. Increasing the feed rate within a certain range can reduce the contact time between the tool and the workpiece, reduce the accumulation of cutting heat, and thus reduce tool sticking. But the feed rate should not be too large, otherwise it will affect the processing quality and tool life. In addition, reducing the cutting depth can also help reduce the sticking phenomenon, especially for thin-walled aluminum products or workpieces with high surface quality requirements.
3. Use cooling lubricants
Cooling lubricants play an important role in Aluminum Product Processing. Choosing a suitable coolant can effectively reduce the cutting temperature and reduce sticking. For Aluminum Product Processing, water-soluble coolants or emulsions can generally be used. The flow rate and pressure of the coolant also need to be properly adjusted to ensure sufficient cooling effect. In addition, in some cases, lubricants can be used to reduce the friction between the tool and the workpiece. For example, the use of extreme pressure lubricants can form a protective film under high temperature and high pressure to reduce sticking and wear.
4. Improve the processing technology
Stage processing is an effective way to improve the processing technology. For some large or complex aluminum products, they can be processed in stages to avoid generating too much heat and cutting force at one time. At the same time, it is also important to adopt the correct processing sequence. Roughing is performed first to remove most of the excess, and then fine processing is performed, which can reduce the contact time and friction between the tool and the workpiece and reduce the risk of sticking. In addition, regular inspection and maintenance of the tools and timely replacement of worn tools can also help reduce the occurrence of tool sticking problems.
