Watch-case Cut′ter.
A machine for cutting the hinge-recesses in watch-cases. The cover or center is clamped to a block which rests upon a disk that is vertically adjustable in a cylindrical turret upon the carriage, and is brought in contact with the rotary cutter to form the hingere-cess. The block has a concave end to receive the convex side of the cover, and the same or another block has a convex or frusto-conical end to receive the concave side of the cover. The upper side of the cover rests against a removable plate and is clamped thereto by the upward movement of the block.Watch-case cutter. |
