Why does the drill bit easily flank when drilling? (跳动大)、钻头小尖(割刃)比中心尖高，这些原因都能造成钻孔时孔口边现象。 If the drill itself does not have an inverted cone, the drill itself has a different axis (large runout), and the drill's small tip (cutting edge) is higher than the center tip, these reasons can cause the phenomenon of the edge of the hole during drilling. The solution is to strictly check all the parameters mentioned above. The panel furniture automatic feeding and unloading CNC opener meets the product drawing requirements.
In addition, if the spindle of the machine tool is different from the quick-change joint, the clamping device of the machine tool is insufficiently configured, and the pressure is insufficient, the Dehong opener will shake the workpiece during drilling, and it will also cause bursting during drilling. The solution is to check that the machine parameters such as quick-change joints, machine spindle, and air pressure meet the requirements for use. The orifice is small and the exit is large when drilling.
(不同轴)，除了出现钻孔时孔口小而出口大以外，还会引起孔爆边。 The drill itself has a large runout (different shafts). In addition to the small orifice and large exit when drilling, it can also cause the hole to burst. The solution is to do a good bit inspection and strictly control the runout. In addition, if the spindle of the machine tool is different from that of the quick-change joint, the orifice will be small and the exit will be large when drilling. The solution is to replace the quick-change joint and the spindle.
The relevant factors of the machine tool are whether the machine tool we choose is suitable, whether the CNC automatic feeding and unloading of the cabinet is not suitable for processing this kind of material, whether the machine tool is leveled, or it may cause tool breakage if it is not leveled. Whether the spindle motor speed is too low, the spindle motor speed is too low, the cabinet automatic loading and unloading machine , each tooth per revolution will increase the amount of cutting tool, so that the cutting force becomes larger, which will cause a broken tool, in general, The spindle speed we use is still better. The problem of the process is whether the machining allowance is unreasonable and whether there is a step-like allowance. In this way, the cutting force will be changed during machining, which will cause vibration and break the tool. It is necessary to increase the semi-finishing. The other is whether the amount of knives is too large. Of course, there are many other factors in the process, I won't go into details here. Relevant factors of the surrounding environment are whether there is a seismic source around and whether the voltage provided is stable. Whether the path of the related factors of the control system is smooth and whether the priority mode is correct, it directly affects the startup speed of the machine tool. The higher the startup speed, the more likely it is to generate vibration, which may easily lead to tool breakage.
