A small pneumatic turbine equipped with a grinding arbor, which has been brought out by the Onsrud Machine Works, Inc., 3908-3932 Palmer St., Chicago, 111., was referred to in October Machinery. The accompanying illustrations show two attachments for this turbine which may be supplied to increase its field of usefulness. The attachment shown in Fig. 1 converts the turbine into a bench machine, and thus provides a convenient equipment for the light grinding and sharpening of tools, cutters, dies, and taps. This unit may be used as a portable equipment or it may be mounted permanently in one place. The attachment illustrated in Fig. 2 makes the turbine suitable for the accurate grinding of 60 degree centers. A detachable plug is inserted in the spindle of the tailstock, and a bracket mounted on this plug holds the face of the grinding wheel at the proper angle so that when the tailstock is advanced on the center, the latter will be ground correctly. The tailstock plugs make the attachment applicable to both large and small machines. |
