Definitions

  • the invention relates to a flexible grinding body according to the preamble of claim 1.
  • Flexible grinding wheels include, for example Coated abrasives, such as endless sanding belts and Sanding sheets equipped with a flexible support are.
  • Coated abrasives such as endless sanding belts and Sanding sheets equipped with a flexible support are.
  • the flexible support the Tensile, compressive and shear forces during the grinding process withstands damage and that the valuable abrasive grains do not leave the bandage too quickly when using it loosen and fall out.
  • the thermal Strength of the flexible grinding wheel in terms of Grain fixation and carrier strength must be sufficient to the high temperatures occurring, especially at Dry grinding operations to withstand.
  • the heat resistance of the grain embedding requires the super cutting materials Diamond and CBN (cubic boron nitride), the through their high thermal conductivity and extremely high Mark hardness.
  • the electroplated abrasive coating has only one layer of abrasive on.
  • the growing metal or nickel layer gradually envelops form-fitting grain scattered in parallel, whereby the embedding height of the desired free-cutting grain exactly over the duration of the galvanic deposition can be regulated.
  • Galvanic bonded abrasive grains can because of the single layer of Abrasive layer cannot be dressed; at most it is possible to see differences in grain peak elevation compensate by touching. Because of this missing Possibility of post-processing is a typical feature galvanically bonded grinding wheel that the moderation the abrasive layer is at best as good as the Permeability of the underlying carrier allows.
  • a nationwide exhibits galvanic metal binder layer with the relevant grain sizes (approx.
  • foil-thin metal layers show however always high sensitivity to Shocks and buckling loads as well as low resistance against Tear stresses due to the low elastic deformability of the metal.
  • Such irreversible, plastic deformations in a comprehensive, close galvanic grain binder layer use as a highly resilient, flexible grinding wheel.
  • DE 39 15 810 is a flexible grinding wheel of the type mentioned above, which is a flexible Has carrier made of electrically conductive material (metal foil), with the tied or unbound reinforcement threads are connected by overlapping seams to the conductive Material is sewn. The seams also connect a mat arranged on the other side of the metal foil made of non-conductive material with the metal foil.
  • the Top is covered in discrete areas with a cover insulated so that areas between the reinforcing threads the metal foil remain free on the galvanic metal is deposited, which forms protruding islands. After that a stabilizing load is placed on both sides of the carrier made of synthetic resin that covers the mat and fills the spaces between the islands and the Islands also covered.
  • the carrier becomes island-side sanded so that the metal islands are exposed. After that, metal is made on the islands together with grinding wheels galvanically deposited.
  • the high oversize is a disadvantage of the electroplated metal, because the reinforcement threads and connecting threads must be surmounted before the galvanic abrasive grain is embedded.
  • the underlying metal foil is not permanently resistant to bending. Alternatively, you can the first galvanic application is also carried out over the entire surface, wherein the reinforcing threads represent galvanic defects; then the wearer has a very stiff, little flexible sandwich structure.
  • This abrasive coating can be used as a coating on one Abrasive media are laminated. You can thereby lowering the kink sensitivity and the tear resistance increase if the area-wide galvanic Abrasive coating is laminated, but occurs in continuous use laminated, flexible sanding belts entirely generally the problem again and again that the elongation ratios and the elongation behavior of the connected Layers are different. This is how it works laminated belts on grinding machines where Redirection and straight running take place in the swelling alternation, the layer facing outwards always on tension and Stress, whereas the inner one Shift at the same time always on compression and relief is charged. These different aspect ratios must be elastically balanced by the lamination adhesive become.
  • EP 0 280 657 is a more flexible one Known grinding wheel, in which a thin metal, especially copper foil is assumed, the on a flexible, electrically non-conductive substrate is laminated so that a carrier in the form of a composite material arises, one side of which covers the entire area is electrically conductive and the other side is electrically insulated.
  • the first step is an electrically non-conductive mask applied, which has discrete openings, and after metal, preferably nickel, together with Abrasive grain applied galvanically. With the galvanic Occupancy reduces the formation of abrasive deposits then on the discrete openings of the mask so that an island-shaped, non-surface covering made of metal (nickel) and embedded grain becomes.
  • a laminated metal foil also a metal layer through metallization processes (Electroless deposition, electroless deposition, vapor deposition or sputtering) applied directly to the substrate become and as described a flexible grinding wheel to be processed further.
  • the disadvantage is that contrary into a smooth, laminated metal foil possible unevenness of the underlying substrate are not compensated for by the metallizations, what in the case of a flat, smooth substrate, for example Foil or the like, irrelevant, at a substrate made of tissue, however, which through the yarn wraps and fabric undulations is significant.
  • metal-coated fabric substrate can be a evenly raised, island-shaped occupancy not built up be so that the embedded grain is not uniformly high and free-standing the flexible grinding wheel towered over.
  • EP 0 263 785 is a flexible grinding body known in the case of a tissue as a substrate it is assumed which is made electrically conductive is by steaming with metal or by weaving of metallic yarn or which by a metallized resin grid is formed.
  • On this Tissue becomes a mask made of polymer, electrically insulating Resin applied under pressure and heat, which contains discrete openings.
  • discrete openings is galvanically metal, especially nickel, in Presence of abrasive grain deposited, which in turn discrete abrasive coverings made of deposited metal (Nickel) and embedded grain.
  • Nickel deposited metal
  • the one as the cathode switched, smooth drum causes the metal or nickel deposition from their surface the discrete openings of the fabric are made and the Grain is only scattered when the metal or Layer of nickel has completely grown through the fabric. After the galvanic scattering has ended, the flexible Abrasive wheel detached from the drum and can a stronger reinforcement can be concealed.
  • this method can also be used perform continuously if instead of rotating Drum through the galvanic bath, endless steel band is used, which is temporary in immovable condition with the masked fabric located.
  • the inside of the bath as a conveyor belt and Steel strip inserted at the end of the galvanic Allocation outside of the bathroom of the flexible Grinding wheel separated and takes as a revolving belt new tissue at the beginning of the bath.
  • Another disadvantage is that only extremely thin, net-like, open, light fabrics form-fitting galvanic of metal (nickel) evenly can be grown through, because the yarns per se Show defects in the galvanic deposition and galvanic layers generally not of any thickness are to be produced free of defects and uniformly thick. That of the smooth drum cathode or the smooth Steel strip cathode outgoing, island-shaped, disc-shaped Metal or nickel coatings lose more and the more true to form the growth side, the thicker the Layers become or the moment when the tissue overgrown form-fitting. That means that the after metal breakthrough has occurred or nickel layer discs as the basis for the galvanic Abrasive grain to be bound is not even and not even are thick.
  • a similar flexible grinding wheel is from the EP 0 013 486 known.
  • An electrically non-conductive mask is applied to the drum, whose discrete openings for a galvanic Separation remains free.
  • One on the cathodically connected Drum tensioned, electrically non-conductive Tissue is made of galvanically deposited metal (Nikkel or copper) only at the discrete positions that are given by the mask. To Penetration of the tissue becomes the growing layer of metal Scattered grain, which is then embedded. Finally, the flexible abrasive wheel from the Drum released and processed.
  • the object of the present invention is in a grinding wheel of the type mentioned with high thermal conductivity, great flexibility, high Dimensional stability and dimensionality as well as a process to specify for its manufacture.
  • a method of making the grinding wheel is specified in claim 20.
  • the invention proposes a substrate, for example a textile structure, such as woven fabrics, knitted fabrics, Fleece or similar, with hard coating compounds on one or both sides with a smooth, even surface on one side with an electrically conductive material, preferably metal, for example copper, and if necessary also on the other side an electrically non-conductive material, preferably to provide a curable resin, for example phenolic resin.
  • the substrate coated in this way forms a carrier for abrasive grain and is dressed to a constant thickness so that the raised areas of the wearer at least on the metal-coated side, still very thin are covered by metal.
  • the carrier receives the necessary flexibility, on the other hand, a high Maintain compression resistance perpendicular to the wearer.
  • Such training is particularly advantageous with a textile structure as the substrate, the ripples which are caused by the yarn wraps, d. H. the crosshair points.
  • the Coatings are form-fitting with the threads connected. The highest thread elevations at least remain still very thin on the metal side, d. H. about 3 - 25 ⁇ m, metal-coated while between the cross-hair points the main amount of the electrically conductive Material (metal) and the electrically non-conductive Material is localized.
  • This so trained Carrier of constant thickness and smooth metallic surface forms an ideal, homogeneous carrier for one full-surface, galvanic coating with a metallic Embedding material, preferably nickel, and with Abrasive grain, which enables a flexible grinding wheel to be produced is which is characterized by a uniform grain grandeur and grain embedding.
  • FIG. 1 shows a substrate 2 for a carrier a flexible grinding wheel in the form of a single chain one-shot fabric 4, with the reference number 6 warp threads and with the reference numeral 8 weft threads are.
  • Other tissue structures are also for the substrate, also knitted fabrics, knitted fabrics, braids and Nonwovens can be used, all of which are cross-hairs exhibit.
  • the crosshair points require a certain amount Waviness or unevenness of the substrate surface.
  • the Fabric 4 is used to form a support 9 for the Grinding wheel on one side (hereinafter the front called) with a metal coating 10 in excess (Fig. 2, 3) and on the opposite side (below Called back) with an electric non-conductive material, preferably a curable Resin, such as phenolic resin, provided existing coating 12 (Fig. 3, 4), where appropriate, adhesion promoter and fillers can also be used.
  • a curable Resin such as phenolic resin
  • the metal for the metal coating 10 is preferred Copper and can by suitable metallization processes, such as metal spraying, vapor deposition, sputtering or electroless plating without external current become.
  • the carrier 9 receives the necessary Flexibility, on the other hand a high compression resistance perpendicular to the beam, by that alternate between the crosshairs 17 massive the metal or the non-conductive material (Resin) are positively embedded and the elastic Spring back of the wearer under compression is suppressed.
  • the caused by the rejuvenation points Flexibility of the continuously metal-coated Fabric is also affected by the fabric construction, d. H. by the type of binding and density and location the tissue crossing points.
  • the back coating 12 can be done without finishing made to measure with a smooth surface by painting the resin in the liquid A state and rolled in the still malleable B-condition and is then cured.
  • This carrier 9 of constant thickness thus formed and smooth metallic surface forms an ideal, homogeneous basis for full-surface galvanic coverage with a metallic embedding material 14, preferably nickel, and with abrasive grain 16, cf. Fig. 5, whereby a flexible grinding wheel 21 can be produced is which is characterized by a uniform grain grandeur and grain embedding.
  • the trained one Metal coating 10 is connected as a cathode.
  • the galvanic metal layer 14 is preferably used and preferably also the underlying metal layer 10, which is connected as the cathode in the galvanic assignment is produced so brittle-hard that it becomes real Brittle fracture without kinking of both metal layers is coming.
  • the flexibility or breakability of the two Metal layers can be increased by the fact that these are subject to residual tensile stress. Through the Brittleness and possibly also the tensile residual stress the crack formation during flexing or refraction facilitated. The danger is avoided that one or both layers of metal just bends, but does not break. This can be achieved by using the metal layers Porous or micro-cracked generated or applied are or defined foreign atoms or defined Amounts of foreign particles can be stored.
  • the galvanic metal layer (nickel layer) is first made easier to break by continuously running from Abrasive grain is interrupted. Brittle and micro-cracked it has a particularly low stretch Metal layer further by choosing an appropriate Electrolytes (e.g. bright nickel plating) and also through appropriately selected deposition parameters.
  • an appropriate Electrolytes e.g. bright nickel plating
  • Said flexible grinding wheel according to FIG. 5 or 7 has a number of other advantages. Thereby, that a full-surface galvanic abrasive grain there is no weak point on the grinding wheel surface, as the island gaps in the interrupted island occupancy according to the status of Represent technology. In contrast to the island-shaped The cutting forces are distributed over the entire surface on the dimensionally stable, hard support and not selectively on a comparatively soft reinforcement, which ultimately sheared off the island grinding surfaces can be. In this area-wide galvanic No tipping moment occurs because the clods 22 or bending points include larger areas. Due to the massive positive anchoring of the underlying Metal (copper) 10 in the substrate (tissue) heavy machining work without loss of abrasive coating enables.
  • the full coverage leads to the difference for island occupancy to an uninterrupted Cut and more uniform grinding pattern because of the Grinding pressure on the entire surface in contact of the flexible grinding wheel is distributed. At the same time the force / grain ratio becomes comparable Scattering density reduced.
  • 5 and 7 is characterized by a very high thermal conductivity from a comprehensive, coherent metallic Grain binder layer with a full coverage connected metallic base 10 connected which is massive the tissue depressions and spaces the crosshairs fill in.
  • the high percentage Weight fraction of this metal (2/3 to 5/6 from Total weight) requires that high amounts of heat from Abrasive grain can be picked up and removed.
  • the massive metal content causes due to the low thermal expansion of the metal only insignificant changes in thickness and length of the flexible grinding body 21 in grinding operations to be recorded, what precise grinding operations important is.
  • Metal spraying to apply the metal coating 10 is by appropriate management of the coating parameters not exclusively on high-temperature resistant Limited substrates. So come as a fabric in addition to metal mesh, inorganic mesh also organic Tissue in question, such as B. aramid, polyamide, polyester or cotton and viscose or mixtures thereof, if sufficient cooling is ensured and the order quantities of metal and thus the transferred quantities Amounts of heat are done in stages. Metal fiber parts in the tissues cause the initially purely mechanical Clamping of the metal spray layer in the Filaments of the yarn achieved higher adhesion values; Moreover they improve the electrical conductivity.
  • the stiffness By impregnating the substrate and further back coatings the stiffness can be adjusted. In addition, the impregnation takes on the task the adhesion of the metal spray layer to the fibers to improve what the basically rough metal spray layer represents good connection points.
  • a metal binder can be added, e.g. B. vulcanization systems, Silane coupling agents, polyurethanes, epoxies.
  • the back coatings themselves are one or multilayer layers of curable resins, especially Phenolic resins, as has already been mentioned, which after application in the still formable B state under high Pressure to be calendered and finally hardened become. Post-processing of the back is regarding the thickness tolerances are not necessary, since it is a coating process with optimal flow properties acts.
