PURPOSE:To perform grinding with extremely high efficiency by performing dressing with the pressing of the grinding face of a cup type grindwheel for dressing by a spring. CONSTITUTION:Grinding is performed by pressing a work 10 to the grinding face 11 of a rotating cup type super abrasive grain grindwheel 1 and at the same time a sliding member 6, namely the grinding face 11 of the cup type grindwheel 3 for dressing is pressed to the grinding face 11 of the cup type super abrasive grain grindwheel 1 for grinding by the tensile forces of springs 15, 17 by adjusting a drum 18. In this case, because of the grinding faces of both grindstones 1, 3 being not coaxial, the grindstone 3 is also subjected to back rotation by the friction force when the grindwheel 1 is rotated and the both grinding faces are moved in almost orthogonal direction each other and so a uniform dressing is performed over the whole grinding face of the grindwheel 1. Consequently no dulling and clogging is caused on the grinding face 11, there is no need of removing the work for dressing and the grinding can be performed efficiently. |
