Conversion. Electric shaver plant. This Norton type C six-inch semi-automatic cylindrical grinder in a New England plant used to grind motor shafts for the firm's normal production of electric dry shavers. It is now grinding spring collets which are used in turning machines to hold the work being turned. Such machines are vitally needed for the war production effort. The conversion of the machine was accomplished by replacing the one-inch vitrified aluminum oxide wheel shown here with a three-inch wheel and by enlarging the feed of the cutting solution. Tolerances on this war work are only .002 inches as compared with the tolerances on the normal production of .0002 inches (see pix #D-2974). Schick Inc., Stamford, Connecticut
