Title: Belt grinding attachment
Inventor: NAGA HIROKAZU
IPC: B24B21/12
Filed: 1991-08-16
Abstract: PURPOSE:To provide a long-lied belt grinding attachment, capable of grinding a concavely curved surface. CONSTITUTION:A hollow tire 19 consisting of rubber material is attached to the peripheral part of a pulley 10 supported on a base 4 free of rotation. This pulley 10 is stuck to the back of an abrasive belt 12. A work's concavely curved surface is pressed to a part, where the pulley 10 in the abrasive belt 12 is stuck, whereby this concavely curved surface can be ground. Therefore, since this curved surface is ground by the abrasive belt 12 longer than the periphery of the pulley 10 in consequence, such a belt grinding attachment as resistible to continuous grinding or polishing for hours is obtainable.
