A new line of grinding machines driven by alternating current motors has recently been brought out by the J. G. Blount Co., Everett, Mass. The machines are built in ½-, 1- and 2-horsepower sizes. The ½-horsepower machine has 8- by 1-inch grinding wheels; the 1-horsepower machine, 10- by 1½-inch wheels; and the 2-horsepower, 12- by 1½-inch wheels. The illustration shows the 2-horsepower machine. These grinding machines are equipped with SKF ball bearings contained in dustproof mountings. The bearings are a light drive fit on the shaft and are secured by lock-nuts. The spindles are made of high-carbon steel and are ground to size. The wheel flanges are machined all over and the inner flanges are pressed to the shoulder of the spindle. The tool tray and water pot are bolted to the collar. They are separate and detachable. The tool-rests are in one piece and adjustable. Each machine is equipped with one coarse and one fine grinding wheel unless otherwise specified. The machines are driven by Westinghouse motors equipped with starting switches of the textile snap type. |
