Definitions
- the fixing of a polishing cloth on a support can intervene of different ways depending on the use of the fabric.
- the fabric having a upper face intended to be in contact with a workpiece and a face by which the fabric is attached to the support, it can be, for example, fixed directly by gluing thanks to an adhesive coating distributed on the face lower fabric.
- a first adhesive coating is disposed between the underside of the fabric and the flexible sheet and a second adhesive coating is disposed between the flexible sheet and the support.
- the flexible sheet makes it possible to obtain a together having a certain rigidity.
- the polishing cloth can not be peeled off support without being damaged.
- the permanent fixation of the fabric on the support makes the use of the tray and its storage impractical and cumbersome. Indeed, this requires storing, for each type of fabric, a support and, when polishing a part that requires several types of fabrics, it is necessary to change, at each operation, the support of the tray on the polishing machine.
- patent application WO-A-0153042 proposes to use a polishing cloth comprising a polishing element comprising a support on which is disposed an abrasive coating, a sub-fabric a surface of which makes it possible to fix the polishing cloth on a tray and a layer with multiple gluing.
- the multiple gluing layer makes it possible to adhere the polishing element on the sub-fabric during the operation of polishing and then replace once used. It can also be formed by a self-adhesive adhesive system in the form of a ribbon comprising for example, an elastic support.
- an abrasive coating comprises a self-adhesive adhesive layer disposed on the non-abrasive surface of a polishing cloth so as to fix the polishing cloth on a support of tissue.
- the self-adhesive layer preferably has a resistance of sufficient peel to allow good adhesion between the polishing cloth and the support when in use but not too high to be removed without tearing off the bottom layer.
- the invention aims to achieve a relatively inexpensive polishing plate and to maintain a perfect adhesion between the fabric and the support, especially when the plate is subjected to a rotational movement, while facilitating a tissue change.
- the adhesion layer is constituted by a web of artificial cellulosic fibers, impregnated of silicone elastomer with an adhesive mass of synthetic rubber, so that the fabric adheres perfectly only horizontally to the support, the free surface of the underlayer being smooth.
- the adhesion layer has a thickness 400 ⁇ m.
- the adhesion means comprise also a layer of polyvinyl chloride, placed between the first layer of glue and a second layer of glue disposed on the support.
- a polishing plate 1 comprises a support 2, preferably in the form of a metal disc and comprising upper faces 2a and lower 2b ( Figure 2).
- a polishing cloth 3 mechanic or mechano-chemical must be attached to the upper face 2a of the support.
- the tray is intended to be arranged by the lower face 2b of the support, in a polishing machine and, preferably, on an element of tray support.
- the tray is generally used in applications various, such as the preparation of metallographic samples, geological or semiconductor substrates.
- the polishing cloth 3 comprises a coating surface 4 allowing the mechanical or mechano-chemical polishing of parts.
- the plateau is animated by a Rotational movement and parts are laid on the surface coating 4 of the fabric, so as to obtain pieces with a polished surface.
- a abrasive liquid for facilitating the polishing of parts such as a suspension diamond, is spilled on the surface coating of the fabric.
- the coating tissue is of the type conventionally used to realize the polishing parts. Thus, it can be diamond, composite smooth, embossed or embossed, or abrasive paper.
- An intermediate layer 5 ensures the fixation of the surface coating 4 on a sub-layer 6 having a free surface 6a smooth.
- the free surface 6a is intended to ensure contact and fixing the fabric on the support 2.
- the underlayer 6 can be in any type of material having a smooth free surface 6a. It can, for example, be in polyvinyl chloride or polyester and the intermediate layer 5 is constituted by a strongly adhesive material such as a material having a acrylic adhesive mass.
- Fixing the polishing cloth 3 on the support 2 is carried out by means of at least one adhesion layer 7 permanently attached to the face 2a upper support 2.
- the permanent attachment of the adhesion layer 7 is achieved by means of at least a first layer of glue 8.
- polyvinyl chloride layer 9 is preferably arranged between the first layer of glue 8 and a second layer of glue 10 disposed on the upper surface 2a of the support 2, as illustrated in FIGS. 1 and 2.
- first and second adhesive layers 8 and 10 are preferably in one acrylic adhesive mass material and the adhesion layer 7 is constituted by a web of artificial cellulosic fibers, and preferably a fibranne®-type canvas, impregnated with silicone elastomer with a mass adhesive synthetic rubber.
- the adhesion layer 7 a of preferably a thickness of 400 ⁇ m.
- the adhesion layer 7 allows the fabric to adhere perfectly to the support, but only horizontally to this one, especially thanks to the free surface 6a smooth of the underlayer 6 of the fabric 3. Thus, the fabric does not adhere perfectly only horizontally to the support.
- By only adhering horizontally to the support means that when pulling on the polishing cloth along a traction axis located in the plane of the interface 11 between the free surface 6a of the underlayer 6 and the adhesion layer 7, the fabric 3 does not move and adheres perfectly to the adhesion layer 7, the plane of the interface 11 being a horizontal plane by relative to the support 7.
- the adhesion layer 7 being fixed so permanent support 2, the fabric 3 adheres perfectly to the support 2 in the horizontal plane.
- the fabric when the plate is rotated according to a vertical axis of rotation s1, the fabric does not move despite the centrifugal force created, the vertical axis of rotation s1 being preferably an axis of symmetry of the 1.
- a single support can therefore be used for different types of fabrics used in the polishing process of a room.
- Such a mode of adhesion advantageously makes it possible to fix reversible polishing cloth 3 on the support 2 without using any element mechanical hooking.
- it is possible to change only the fabric of polishing of the tray, at each new step of a polishing process of a piece, while retaining on the polishing machine, the same support covered by the same adhesion layer 7.
- It also makes it possible to store, only the polishing cloths and no longer the trays. This allows, In particular, to save time during the polishing process, the change tissue being performed more quickly. This also reduces storage space polishing trays because the space required for store a predetermined amount of polishing cloth, is less than required to store the same amount of tissue respectively glued to a support.
- the cost of the adhesion layer 7, the adhesive layers 8 and 10, and the polyvinyl chloride layer 9 is relatively low by compared to the cost of a magnetic coating and it is easier to clean the fabrics alone.
