What Is An Ultrasonic Milling Machine

What is an ultrasonic milling machine

Ultrasonic milling equipment is particularly suitable for deep and small holes of difficult-to-machine materials. When twist holes are used to drill deep holes of difficult-to-machine materials, many problems will occur, such as the difficulty of cutting fluid entering the cutting zone, high cutting temperature, rapid blunt cutting edges, cutting The force is large, the drill is easy to break, the chip removal is difficult, and the tool needs to be retracted frequently. The accuracy of the machined hole is poor, indicating that the roughness is large and the life is short. Using ultrasonic rotary drilling processing, the effect of ultrasonic vibration reduces the frictional resistance between the chip and the workpiece, makes the chip discharge smoothly, does not need to retract the chip, and is easy to achieve automation; if the amplitude is selected properly, the axis of ultrasonic rotary processing Force is reduced by about 30% compared with ordinary cutting force, thereby improving drill life. It can be seen that ultrasonic rotary machining is an effective method for deep and small hole machining of difficult-to-machine materials.

    **. Ultrasonic drilling and milling machine can greatly reduce the cutting force, reduce the frictional heat, increase the life and reduce the roughness value of the processed surface, which has the following characteristics:

In the process of drilling and milling, the front is not always in contact with the workpiece, but in a state of regular contact and separation; the regular pulse impact cutting force replaces the continuous cutting force; the regular forced vibration of the (or workpiece) replaces Irregular self-excited vibration with the workpiece; most of the cutting force comes from (or the workpiece) vibration, and (or the workpiece) movement is only set to meet the workpiece processing geometry.

   Second, in vibration drilling and milling, the actual instantaneous drilling and milling speed is increased due to vibration, and the dynamic impact force is applied to the workpiece, which reduces local deformation, concentrated force, and instantaneous cutting force increases. In this way, a larger wavefront shear stress is obtained, which is conducive to plastic embrittlement of the metal; reducing plastic deformation is favorable for cutting; this advantage is more prominent in the processing of superhard materials.

   Third, it is beneficial to cooling under the action of ultrasonic waves. The high-speed vibration is very beneficial for heat dissipation. At the same time, because the front surface is periodically detached from the workpiece, it makes it easier for the cutting fluid to enter between the workpiece and the system, which also increases the heat dissipation capacity of the system.
