CNC machining center is an automatic machine tool for efficient machining with many functions. Bearing is a part of CNC machining center, its main function is to support the rotation of the machine, reduce the coefficient of friction generated in its movement and ensure its rotary accuracy.
First. Knock method
When knocking, the force is concentrated on the inner ring of the bearing; this method is relatively simple, but it is easy to damage the bearing. When dismantling the bearing underground with an object pad, and then use a hand hammer to knock lightly before the bearing will be removed.
Second, pull out method
When using the special puller, just turn the handle to pull out the bearing. It must be noted that the puller is stuck on the end face of the inner ring of the bearing, and the bending angle of the puller is less than 90°.
Third, push pressure method
It should be noted that the method can be achieved through the press, which is safer for the bearing, but one of the things to note is that the pressure point of the press should be placed on the center of the shaft.
Fourth, the hot dismantling method
If the bearing will be about 100 bearings with oil kettle injected into the bearing, according to the principle of thermal expansion cooling contraction, the bearing will expand when heated, but at this time can be pulled out with the assistance of pulling piece; use this method to be small, to avoid being burned.
Five, induction heating method
This method is better, cnc machining bearing circle to produce induction current, bearing heat expansion, easy to remove the spindle.
