Definitions

  • the invention relates to a device for vibratory grinding of workpieces, consisting essentially of a closable work container rotatable about a first axis, a frame rotatable about a second axis in which the work container is rotatably mounted, a frame in which the frame is rotatable is stored, and from drive devices for the rotation of the working container and the frame.
  • Vibratory grinding is understood to mean surface machining of workpieces in a bed of treatment bodies, a relative movement being generated between the workpieces and treatment bodies by the mixture being circulated or otherwise moved in a work container.
  • a device of the type mentioned has become known for example from DE-OS 17 67 318.
  • the working container is rotatably mounted about two axes passing through the container, crossing or intersecting in the container.
  • the device is assigned a drive device by means of which the working container can be rotated about one or both axes of rotation at such a high angular speed that the container contents are held against the container wall as a result of the centrifugal force.
  • the desired relative movement between the workpieces and the treatment bodies is created in the container.
  • the small angular velocities previously used in such devices which cause the contents of the container to circulate under the influence of gravity allow a much more effective surface treatment to be achieved. Further improvements in work performance should be achieved if the container contents are rotated about both axes at a correspondingly high angular velocity or if the two axes are arranged at an oblique angle to one another.
  • the two axes arranged at a vertical distance A from one another expediently run at an angle ⁇ of 40 to 90 ° to one another. It is advantageous if two independently controllable drives are provided for the working container and the frame.
  • the working container consists of two flat end faces perpendicular to the first axis and flat lateral surfaces running parallel to the first axis is formed.
  • the working containers can preferably be formed by two square or octagonal end faces and four or eight lateral surfaces.
  • one of the outer surfaces has a closable loading opening.
  • the influence of the center distance A on the effectiveness of the finishing grinding was determined by tests. Iron angles with the dimensions 30 by 30 by 3 mm and a weight of 110 g were processed in a mixture of grinding wheels, water and processing aids for 30 minutes and the weight loss was then determined.
  • the speed of rotation of the container was uniformly 135 rpm, which corresponded to a centrifugal acceleration of 1 G.
  • the speed of rotation of the frame was varied in steps between 80 and 237 rpm, the centrifugal acceleration changing between 1 and 9 G.
  • the center distances A were 0, 20, 50, 80 and 100 mm. Under these conditions, the weight losses in g per kg shown in Table 1 were determined.
