Definitions
- the invention relates to a disk support for polishing which overcomes the disadvantages mentioned above by changing the polishing disc without the abrasion being too strong during the first few seconds of use, and while getting however good flatness.
- the following polishing disc holder the invention is defined by claim 1. It is made up of a disc-shaped body. A support centering hole is provided in the center of one of the faces of the body. A training hole for cooperate with a device training finger rotational drive is provided eccentrically in this same face. A coating of more material tender that that of the body is applied to the other side in a thickness between 5 ⁇ m and 4 mm.
- the coating has a hardness shore D greater than 12 so as not to obtain a profile dented in the sample to be polished.
- the coating is polytetrafluoroethylene. This makes it possible to take off and re-stick an abrasive paper or polishing cloth used previously, for example for polishing a different material, repositioning a sandpaper or polishing cloth that would have been improperly applied to the substrate and self-eliminating most air bubbles that have been trapped accidentally when laying sandpaper or polishing cloth. Due to the very low power sticky polytetrafluoroethylene, air bubbles are driven off by the pressure applied to the workpiece.
- the coating can be applied by spraying, for example by applying three successive layers of 25 microns, but we can also apply the sheet coating if necessary laminated, these leaves undergoing treatment chemical on one side which allows them to be glued on a support with araldite or double adhesive face.
- the coating can also be in the form a grid or a canvas, just like the disc-shaped body.
- the body can also be laminate, aluminum plate or other hard material 1 to 5 mm thick being bonded to a substrate cast iron or aluminum.
- the support comprises a body 1 made of aluminum disc shape with two faces 2 and 3. In the center of the face 2 is formed a blind hole 4 for centering, while that on this same face 2 are formed seven holes 5 and 7 training blinds intended to cooperate with a finger drive of a rotary drive motor.
- the arrangement of holes 5 and 7 is as it is always one able to cooperate with the finger of a machine whatever the polisher.
- a coating 6 in polytetrafluoroethylene in one thickness 100 microns is applied.
- the profile of the sample is good.
- the profile of the sample is good.
- the profile of the sample is good.
- the sample profile is excellent.
- Polisher equipped with an aluminum plate with PVC coating 2000 ⁇ (2 mm)
- the sample profile is excellent.
- Polisher equipped with an aluminum plate with PVC coating 4000 ⁇ (4 mm)
- the profile of the sample is rounded.
