Another polishing machine known as the “Western" No. 10 has been added to the line of polishing and grinding equipment built by the St. Louis Machine Tool Co., 932 Loughborough Ave., St. Louis, M0. The machine has a wide-face pulley and long bearings for the wheel-spindle, the bearings having large oil reservoirs and being amply provided for filling and draining. Circulation of lubricant is accomplished by means of chains. It will be seen that the lower half of the bearings is cast integral with the column. The arbor is made from 0.40 carbon steel, and has extra coarse-pitch square threads. The machine may be furnished with taper-point arbors, either right or left, when desired. A few of the principal dimensions are as follows: Length of arbor, 48 inches; distance between wheels, 38 inches; and height from floor to center of arbor, 34 inches. |
