Combine 1 1/2 cups sugar and oil in a bowl; stir well. Add orange juice and next 6 ingredients (orange juice through egg whites); stir until well-blended. Gradually add flour, 1 cup at a time, stirring until well-blended. Shape dough into a ball, and wrap in plastic wrap; chill 1 hour.
Divide dough into 4 equal portions. Roll each portion of dough to 1/8-inch thickness on a lightly floured surface; cut with a 2 1/2-inch round cutter. Place cookies on baking sheets.
Combine 1/2 cup sugar and cinnamon; sprinkle on top of cookies. Bake at 350° for 12 minutes or until lightly brown around edges.
