Cup vibration
Cutting vibrations generally occur in the long axis of the long tree and the turning point of thin parts.
Once the vibration has been intensified, a fierce vibration of more than dozens of μm will occur, which is generally accompanied by a great noise. In the cutting treatment, the vibration can exceed 100 μm.
The damage to the cutting vibration The vibration generated in the treatment of the cutting of metals is a very harmful phenomenon.
1. Assign the surface quality of the parts. Assign the surface quality and the performance of the parts;
2. Reduce the latter and the vibrations of the lifespan of the tool, the craft system will continue to resist the role of the dynamic cross load.
3. The noise generated in the healthy vibration of the operator will also endanger the health of the operator. In order to reduce vibrations, the quantity of cut should sometimes be reduced to reduce the production efficiency of machine tools.
Therefore, in order to ensure the normal operation of this machine treatment equipment, the cutting of the cutting of tremors has become increasingly important. The cause of the classification of cutting vibrations classification of cutting vibrations requires the following three conditions at the same time when the cutting part occurs:
The first is that the rigidity of the technical system, including the tool, caused its inherent frequency.
The second is that the cut generates a sufficiently large external force,
The third is that the frequency of this external force is the same as the inherent frequency of the craft system.
How to eliminate the vibration cut?
（1) Solving ideas The first is to reduce the cutting force to the smallest, and the second is to strengthen the static rigidity of the knife system or the room and the room; External stimulation cutting force.
(2) corresponding strategy 1. The first is to reduce the cutting force to a minimum
(1) Use sharp blades to reduce the cutting force
(2) Use a small knife cutting arc radius when cutting the depth
(3) For a long -length knife and long axis parts of the sleeper post, a 90 -degree main tool must be adopted
(4) The thin rod striker is the most conducive to the vibration of round blades and strawberries.
(5) Long rods and the cutting of cutting of deep cutting cutting often adopt the insertion and milling method
(6) Face striker uses sparse teeth and a strawberry cutter without distance to reduce grinding and vibrations
(7) The smaller the angle of the blade of the blade of the inner hole. 2. Improve the static rigidity of the knife bar
Use the global hard alloy or the heavy metal knife pole to increase the static rigidity of the knife.
