Combination wire wheel using labor personnel more cautious, if not careful in the production process is easy to be hurt, and wire wheel wounding in operation is relatively large. Therefore, using a combination of wire wheel machine were producing a to put all the spirit at work, follow the rules of using the machine using the to do other things should to switch the machine off, go on to do other things; what accident occur during the operation of the machine should be first turn off the power supply, and check the machine. The structure of the wire wheel of the combined wire wheel is the ceramic ring in the outside of the bearing. When the wire, through the ceramic ring surface, ceramic ring with wire, rotation, which will be converted to static friction sliding friction. But at the start and stop, in order to overcome the inertia, there will be a partial sliding friction.
