Abstract
A meat cutting pulley wheel is formed with an aluminum body and a cast iron ring bonded to the body rim. The method of manufacture includes machining the ring, preheating the ring and mold, inserting the ring into the mold, pouring molten aluminum into the mold, cooling in the mold and final machining of the ring.
Claims15
The method of manufacturing a composite aluminum-cast iron meat cutting band saw wheel, comprising the following steps:
- (a) producing a cast iron ring;
- (b) machining at least the periphery of said ring to a predetermined dimension;
- (c) preheating said ring;
- (d) preheating a wheel mold;
- (e) inserting said ring within the mold in a predetermined position;
- (f) pouring molten aluminum into said mold;
- (g) cooling the composite aluminum-cast iron wheel formed in the mold while it is in the mold;
- (h) removing the composite wheel from the mold;
- (i) machining the periphery of the composite wheel to final size with the cast iron ring being the exposed working surface for engaging a band saw blade.
