After the use of woodworking engraving machines, some customers reflect the wear of the tools during the use of the tool. Then how to reduce the tool wear of woodworking engraving machine and increase the service life of the tool. In addition to solving these problems, we also helped you to sort out the precautions for purchasing woodworking engraving machine tools.
First, woodworking engraving machine tool wear
The main reasons that affect the tool wear of woodworking machine are as follows:
1, cutting amount: including spindle speed, feed rate, path spacing, knife depth and other parameters.
2, tool type tool data: select the appropriate tool for the machining depth and its angle, material
3. Direction of the cutter: The design of the engraving program must be related to the use of the cutter.
4, the knife way: according to the material must choose the appropriate knife direction.
5. Cutting fluid: The method of auxiliary engraving must be appropriate.
Second, woodworking engraving machine tool wear judgment
1, according to the movement state of the engraving machine in the process to determine the wear condition of the tool, such as processing parameters, cutting amount and other settings are reasonable, the engraving machine in the processing vibration is very large, and a "beep" sound, you can be sure The tool has reached a state of rapid wear and must be changed immediately.
2, woodworking engraving machine tool wear, the amount of wear, the most important and most direct way to distinguish is to "listen" sound, if the cutting sound is very "heavy" or issued a "screaming and harsh" sound, indicating the processing status of the tool If it is not normal, the machining can be stopped at this time. If the tool quality problem, the tool clamping problem, and the tool parameter problem are removed, it can be proved that the tool is worn out, so it is necessary to suspend the machining and change the tool.
Third, extend the life of woodworking machine tool
In the work of woodworking engraving machine, tool wear and broken knife are inevitable, how to extend the service life of the tool! Changsha Xinye CNC Equipment Manufacturing Co., Ltd. summarized the following points:
1. Choose the right tool: For the high hardness material, use the corresponding tool, otherwise it is easy to break the knife.
2, the maintenance of the tool: the processing must be properly kept in the tool, ready for the next use of the tool. When employees get off work, be sure to separate the tools and materials.
3. During the engraving process, the tool broken inside the material should be taken out in time, because when we re-engraving, it is not necessary for the engraving knife to hit the short knife and break again.
4. Engraving speed: When carving high hardness materials, do not cut the knife too fast.
Fourth, choose woodworking engraving machine tool precautions
1. Choose according to tool complexity, manufacturing and sharpening cost: the tool life of complex and high precision should be higher than that of single-edged tool. For multi-knife engraving machines, combination engraving machines and automatic machining tools with complicated tools, tool changes and tool adjustments, the tool life should be selected higher, especially for tool reliability.
2. When the productivity of a certain process in the workshop obviously limits the productivity of the whole workshop, the tool life of the process should be selected lower; when the total expenditure of the whole plant is shared in a certain process, the tool The life expectancy should also be chosen lower.
3. In the case of large-scale finishing, in order to ensure that at least one pass is completed and the tool is changed midway during cutting, the tool life should be determined according to the accuracy of the part and the surface roughness.
