Abstract

The invention relates to a special processing method and device of a roller of a hot rolling machine. The method and device mainly solve the problem that a high-precision, smooth and complete rolling hole cannot be obtained since the precision error is produced when roller blanks are processed one by one in the prior art, thereby influencing the working quality of the rolling machine when rolling. Three to-be-processed roller blanks are mounted on a square frame and are synchronously processed by a centre formed by the roller blanks on the rolling machine. By adopting a special roller processing device and method, a mounting frame equipped with the roller blanks on the rolling machine is placed on the processing device; the cutting tool on the processing device processes the centre surrounded by the roller blanks so as to form a complete and smooth rolling hole; the error caused by assembling of a plurality of roller blanks is effectively avoided, the rolling hole precision of the roller is improved, thereby improving the production quality of the workpiece when the rolling machine is in rolling.
