Technical Field
The invention belongs to the technical field of roller repairing and polishing, particularly relates to a polishing device for roller repairing, and particularly relates to a roller grinding machine for roller surface grinding and repairing.
Background
The commonly used repairing method of the roller comprises the following steps: surfacing of the surface of the roll body and the roll neck; turning and grinding the surface defects of the roller; sleeving a roll body and a roll neck (red mounting or bonding method); welding of broken roll necks or thermite welding; and (3) a mechanical repairing method. And the roller grinder can realize the grinding and repairing of the roller surface.
When some existing rollers are ground and repaired on a grinding machine, the rollers are placed on a center frame, and in the rotating and grinding process, the rollers can vibrate to cause errors on the grinding surface, so that the repairing is affected.
