A method and an apparatus used for crowning a band saw pulley wheel (3,4) is presented. Said method comprises mounting a base fixture (10,11,12) to the frame of the band saw (2), mounting a CNC x-y table (13,14,15) to said base fixture, mounting a tool piece (17) to said CNC x-y table, aligning said CNC x-y table and said tool piece with the pulley wheel to be crowned (3), programming the CNC x-y table such that once the crowning operation is started said tool piece is brought into contact with the surface of the pulley wheel and then follows a specific path such that the pulley wheel is crowned with a specific profile, driving the pulley wheel via a drive motor (32), and starting the crowning operation. In this way, a very accurate crown can be applied to the pulley wheels without needing to remove the pulley wheels from the bandsaw. |
