AUTOMATIC SUFACING MACHINE
The automatic surfacing machine illustrated above is specially designed for finishing hardened and case-hardened surfaces, such as the faces of dies and the like. The surfacing is effected by an emery disc, which, in addition to a rotating motion, has also an endwise reciprocating motion. This latter is effected by a crank-pin in a worm-wheel driven by a worm sliding on a key at the rear end of the spindle. The table can be made to rise and fall by a screw and hand wheel to set the work vertically and has an automatic traverse endwise. The length of the traverse can be adjusted by the blocks on the front of the bed. These meet at each end of the stroke, with a lever connected to the striking gear, and thus operate the strap fork. A double incline on the striking bar serves to raise a counterweighted lever as the table approaches the end of its stroke, and descent of the same lever, after it has passed the top of the incline, completes the travel of the bar. |
