Definitions

  • the invention relates to a device for mechanical Machining, especially for grinding and polishing the Surface of workpieces, especially specimens, consisting from a rotatable machining tool Support body with an interchangeable on its work surface held, foil or paper-like processing surface.
  • test specimens usually designed as thin slices, at least proportionate to the area to be examined have a smooth surface.
  • a smooth surface will produced by at least one grinding, lapping or polishing process.
  • Devices are used for this processing of the test specimens become known, which consists of a disc-like, rotatable Support body exist on its so-called work surface an interchangeable machining surface is held. The rotatable The supporting body then forms the so-called with the processing surface Machining tool against which the in a special Holding test specimen with a predetermined Contact pressure can be pressed.
  • the processing surface is film or paper-like and with grinding or polishing agents with different fineness Mistake.
  • a special clamping ring on the work surface of the support body to secure.
  • This is cumbersome and time consuming.
  • It is also known to apply the disc-like machining surface to provide its back with an adhesive layer over which then the processing surface on the work surface of the supporting body is held.
  • Such an adhesive layer is in paper-like Machining pads cannot be used.
  • the support body As a kind of magnetic disk form over which the machining surface in which a metal foil is incorporated, adheres to the support body.
  • metal particles especially metal dust on the magnetic disc on the processing surface sticks, causing the surface of the specimen is adversely affected.
  • the invention is based on the object of a device for machining, especially for grinding and polishing, the surface of workpieces, especially test specimens to be trained so that any paper or film-like processing surface without additional pretreatment and without a special one Clamping device on the work surface of the supporting body can be attached, whereby it should be excluded that metal particles, especially metal dust, on the processing surface sticks.
  • the working surface of the support body several distributed and has channels connected to a suction line and the processing surface can be removed by vacuum on the work surface the supporting body is secured.
  • the processing surface becomes without special aids, but certainly on the Work surface of the support body held. Special treatment processes the processing surface is no longer required; Metal particles, especially dust, do not remain on the processing surface be liable.
  • FIG. 1 of the drawing is of a device for mechanical Grinding and polishing specimens a storage 1 shown, which in a known, not shown Way is used in a housing.
  • This housing carries also a drive motor, for example via a Toothed belt driven a pulley 2 only partially drawn which is on a shaft 3 rotatable in the bearing 1 is attached.
  • the shaft 3 carries the pulley 2 on it opposite end of a plate 4 on which a support body 5 is attached is.
  • the support body 5 takes on its so-called work surface 6 a paper or film-like processing covering 7 on the corresponding grinding or polishing process corresponds.
  • This processing surface 7 is on the work surface 6 of the Support body 5 secured by negative pressure.
  • radially extending, groove-like channels 8 incorporated, to the branching channels 9 can connect.
  • the channels 8 open in an axial bore 10, which is in the support body 5 and Plate 4 is located.
  • This Passage 12 is out through a circumferential seal 13 completed and only goes into a hole at one point 14 over to which a suction line known per se, not shown connected.
  • This suction line leads to one known vacuum device, for example, by a small fan can be formed.
  • this fan is switched on and the processing layer 7 is safely on the work surface 6 of the support body 5 held. After switching off the fan, the Machining surface 7 can be removed easily.
  • the channels 8 run at a distance below the work surface 6, also radially, in Support body 10. Smaller channels 9a now run from this channel 8 to work surface 6. Via channels 8 and the smaller ones Machining surface 7 can also pass through axial channels 9a Vacuum secured on the work surface 6 of the support body 5 become.
