Title: GRINDING DEVICE FOR SCARF SANDING
Abstract:
This grinding device for scarf sanding is provided with: a main frame which rotates around a rotational axis, and which is capable of parallel movement in a horizontal plane that orthogonally intersects the axial direction; a first rocking frame which is disposed away from the main frame in the axial direction with an interval therebetween, and which is attached to the main frame so as to be capable of rocking; a pitch feeding frame which is attached to the first rocking frame so as to be capable of parallel movement in the horizontal plane intersecting the axial direction; and a second rocking frame which is attached to the pitch feeding frame so as to be capable of rocking. The first rocking frame is capable of rocking, with respect to the main frame, around a first support point offset from the axial centre. The second rocking frame is provided with: a contact element which comes into contact with the surface of a material to be ground; and a grinding stone for grinding the material to be ground. The second rocking frame is capable of rocking, with respect to the pitch feeding frame, around a second support point provided on an orthogonal line from the centre of the contact position of the contact element which is offset from the axial centre.
