How to solve the problem of engraving machine broken knife

Many friends who purchase engraving machines often encounter broken tools frequently in processing projects. Why do they break the knife frequently?
    The occurrence of a broken knife is actually a change in the force of the cutter or an excessive influence factor of itself. Then the relevant reason is the seven points we said: tools, materials, machine tools, processes, environment, control systems and auxiliary equipment.
    The condition of the tool can be further divided into: the hardness of the tool, the strength of the tool, the sharpness of the tool, and the length of the tool that is particularly important, and the smoothness of the tool rake face. The hardness of the tool is related to the coating material, the number of grains of the tool itself, and the microscopic geometric angle of the tool. The factors related to the strength of the tool are the material of the tool itself, the influence of alloying elements. The sharpness of the tool affects the condition of the tool grinding, the number of grinding wheels used, the number of pieces of the tool itself, the degrees of the rake angle and the back angle.
    Whether the material is related to the material or not, the hardness of the material is not too large.
    The machine-related factor is whether the machine tool we choose is suitable, is it not suitable for processing this kind of material, whether the machine tool is leveled, and the level of the machine may cause the broken knife. Whether the spindle motor speed is too low, the spindle motor speed is too low, the amount of knife per tooth per revolution becomes larger, so the cutting force becomes larger, which will cause the knife to be broken. Generally speaking, the spindle speed we use is still high. Some are good.
  The problem of the process, whether the machining allowance is unreasonable, whether there is a stepped margin, so that there will be a change in the cutting force caused by the vibration during the machining, resulting in the broken knife, so it is necessary to increase the semi-finishing. The other is whether the amount of knife is too large. Of course, there are many other factors in the process, I will not say much here.
    The relevant factors of the surrounding environment are whether there is a source around and whether the voltage supplied is stable.
    Whether the path related to the control system is smoothed or not, and the priority mode is correct. It directly affects the starting speed of the machine. The higher the starting speed, the more likely it is to generate vibration, which can easily lead to broken tools.
    The related factors of the auxiliary equipment are whether the chip removal is smooth, whether the secondary cutting is avoided, and the main problem is the upper knife.
    Whether there is dust on the cutter and the chuck, and the strength of the upper cutter is too large. The chuck and nut are not intact. It is important that the tool extension is not large.
    In fact, this is a method of analyzing problems. When problems arise in processing, we must analyze them from these aspects, and we must combine the actual situation at the time. Or we have a bad processing effect and efficiency during processing. There is no result in this aspect improvement. We can try it on the other hand. There are many factors that affect the processing, that is, there are many methods that we can use.
