Not only can finished treated obtain various natural color effects, but other materials, with large range color, may superimposed successfully. The color the metal itself lustrous metallic white; but comes from the mill, the color may range even metallic gray. light appearance desirable, the material subjected various finishing operations which brighten the surface. Mechanical brightening opera- tions aluminum yield excellent results long the characteris- tics the metal are kept mind. Both the machines used and types operations are similar those used other metals, the differ- ence being chiefly the technique, the choice wheels, wheel speeds, abrasives and lubricants. ten- dency “drag out” can avoided the use softer wheels and finer abrasives, while excessive metal heat can through slower wheel speeds and, particularly with felt wheels, con- stant lubrication. The complete polishing process consists four operations: rough- ing, oiling, buffing and coloring. Roughing done with either rag canvas wheel. layer glue painted over the grind- ing face and powdered emery, graded from No. No. 100, embedded it. The wheel usually operated peripheral speed 6000 f.p.m., and the sur- face being roughed kept smeared with tallow similar lubricant. Oiling differs from roughing chiefly the use softer wheels and finer abrasives, and heavy oils, rather than tallow, are usually used for greasing the wheel. Buffing differs from the first two operations that the abrasive applied loosely the face the wheel. The wheel softer than before, consists stitched linen disks.

Abrasives used include compounds, Vienna lime (some- times mixed with little emery flour), and rouge. Just tripoli made into cakes for buffing, the lime polish rouge mixed with suitable grease base for color- ing. Before coloring, the articles are washed benzine similar solvent and dried sawdust, thus removing any coarser particles that might carried along from earlier operations.

The elevator the molding end auto- matically returns the bottom the elevator shaft and receives empty tray and then automatical- rises the molding position. This entire cycle performed auto- matically and completed while the molders are working the next mold. When the bench floor receives metal, molder merely throws switch which changes the controls for the pouring cycle, dur- ing which the elevator the pour- ing end rises and receives tray molds which are ready poured. The elevator then descends the pouring level, and the weight-clamping device automatic- ally moves out and clamps the When the molds the tray are poured, the molder presses another button and the molds move with the weight-clamping device. The elevator then returns the top and receives another tray molds. The elevator thereupon descends the pouring position, weight-clamping device rises from the poured molds and moves out and clamps the next tray poured. This completes the pour- ing cycle. The shakeout cycle the same the pouring cycle. One man the mold end shakes the molds out the grating, and returns the bands and bottom boards the trays. This places the boards and bands position for the molders the next day. should especially noted that both molders and pourers make the minimum number moves and then only for short distances. This equipment eliminates manual shift- ing and placing weights. Sand conditioning also eliminated. The clamping bars move and out automatically. This another fatique-saving feature the equipment.
