Abstract
Chamfer processing is carried out by making plate material W end faces come in contact with rotating grinding belts. The grinding surfaces of the opposing side by side grinding belts are on the centerline in the thickness direction of the plate material. The center point is considered the pivot point as seen from the plate material end faces and in distance is smaller than the thickness of the plate material. Pivot motion of the plate material is carried out in the rotating direction of grinding belts. This chamfer processing method and device enables chamfer in a small curvature radius without applying a heavy tension load on grinding belts, and performs uniform deep chamfer processing of multiple plate material simultaneously.

A chamfer processing method for plate material comprised of:
- making said plate material end faces come in contact with rotating grinding belts;
- wherein the grinding surfaces of the opposing side by side grinding belts are on the centerline in the thickness direction of said plate material;
- the center point is considered the pivot point as seen from said plate material end faces and in distance is smaller than the thickness of said plate material;
- the pivot motion of said plate material is carried out in the rotating direction of said grinding belts.
The chamfer processing device is characterized by said grinding belts arranged in a mode to be rotated by a driver pulley and follower pulley;
- a plurality of holder guides is arranged facing said grinding belts along the rotating direction of said grinding belts;
- the upper surface of said holder guides is formed in a concave circular arc, which serves as the radius for the pivot motion of the work holders;
- a plurality of work holders carry out the pivot motion along the circular arc arranged in the upper sliding surface of each holder guide;
- multiple work holders retain each correlated plate material and face the plane of each plate material to carry out the chamfer processing in an orthogonal direction with the rotating grinding belts;
- an interlocking linkage mechanism synchronizes the pivot motion of each work holder carried out on each holder guide;
- the linkage mechanism is equipped with a source drive for the reciprocating motion;
- the grinding surface of the rotating grinding belts is held against each work holder retaining each plate material in contact with the chamfer end faces and executed in combination with the pivot motion of each work holder.
