Grinding device for rotary driven circular blades has positioning means determining relative position between circular blade and grinding element and interacting with housing of blade or with stop formed thereon

摘要

The grinding device has a grinding element (4) rotatable parallel to the axis of the circular blade (12). A support element (7) movable vertical to the axis (3) of the grinding element has a support trough (20) to house the area (17) of the handle (16) directed parallel to the axis of the blade in a direction parallel to the axis of the grinding element. A positioning means (22) movable parallel to the axis of the grinding element and interacting with the housing of the blade or with a stop (15) formed on the housing determines the relative position between the blade and the grinding element.
