Abstract

1,024,772. Centreless grinding. H. MODLER. Jan. 10, 1963 [Jan. 18, 1962], No. 1269/63. Heading B3D. A device for the centreless grinding of round workpieces comprising a grinding wheel, a control disc and a work-support having prismatic work contacting surfaces to contact the workpiece at two points, and which is pivoted about a stationary point, is characterized in that the angle # and the angle # are each integral even multiples of the angle #, where # is the angle between the radii from the centre of the workpiece and, respectively its point of contact with the grinding wheel and its point of contact with the support nearest thereto; # is the angle between the radii from the centre of the workpiece to the points of contact with the support; and # is the angle between the lines between the centre of the workpiece and the centres of the grinding wheel and control disc, respectively. A work support 54, Fig. 22, is pivoted at 71. The angles #, # and # are 36 degrees, 108 degrees and 18 degrees respectively. The application to internal grinding is shown in Fig. 30. The grinding of thin-walled rings is mentioned. In a through-feed centreless grinder, a number of work-supports are used, each being capable of pivoting independently of the others. Apparatus for grinding cambered workpieces, e.g. crowned rolls, generally resembling that described in Specification 794,364, comprises a spherical steel control member 73, Fig. 26. The workpieces are held in prismatic shoes 77 mounted on arms 74 freely pivoted about axes 75 and received in slot-shaped notches of a rotary cage 76. It is stated that the above arrangements result in the grinding wheel being self-dressing.
