Description

In the second paper, some remarkable results concerning the modification of the machine itself are described.<BR>Summary and Conclusions :<BR>1) To test the lathe for the accuracy concerning the bed surface and the carriage travel, a fine steel piano wire was stretched longitudinally above the bed under a certain amount of tension the deviation with regerd to the bed surface was observed with a micrometer microscope. Previously the wire was heated electrically under less tension to get rid of its initial distorsion to a great extent.<BR>2) The bed surface was scraped so as to get the readings within the limit of 0.05 mm (over 7.6 m length in the vertical plane).<BR>3) The readings of the carriage travel were within the limits of +15μ and -10μ (over 3 m length in the horizontal plane).<BR>4) A crowning mechanism which is simple and reliable was deviced.<BR>5) The error in the diameter of the rubber roll finished by this machine tool was within ± 0.03mm.
