Definitions

  • the present invention relates to a grinding net, a method for producing a grinding net, a grinding wheel with a grinding net, a grinding device and a use of a net for producing a grinding net.
  • An abrasive usually contains an abrasive carrier to which abrasive grains are fixed, for example by means of a binder.
  • perforations or holes are made in full-surface materials. That's the way it is for example WO 2006/074058 It is known to use a perforated or slitted and stretched film as the abrasive carrier. In particular, small perforations in the range of a few millimeters, as they are desirable for use in fine grinding, but are very expensive and expensive to produce.
  • An abrasive product which has a series of mutually parallel abrasive filaments. These are arranged on a series of mutually parallel base threads, which run transversely to the abrasive threads. In this abrasive product, however, only the abrasive threads and thus only about half of all threads come into contact with a surface to be machined due to the geometry.
  • the gaps formed between the abrasive filaments cause the abrasive action to be strongly dependent on the direction of movement during the grinding process: a movement parallel to the abrasive filaments leads to furrows and thus to an unsatisfactory grinding pattern.
  • the abrasive filaments may twist relative to the base filaments as they move perpendicular to them, which may result in high stress on the contact points between the base filaments and the abrasive filaments.
  • the abrasive is designed as a grinding net, which contains a carrier net with a first main surface, which is essentially flat, as an abrasive carrier.
  • a net is understood to mean a substantially planar structure which has a multiplicity of webs and junctions to which the webs are connected to one another.
  • the webs define openings, which are formed directly in the production of the sheet-like structure.
  • a net can be extruded directly in one piece or be connected from thread or strip-shaped strands such as by knitting, weaving, braiding, knitting, crocheting, sewing, embroidery, bobbin lace or knot to form a two-dimensional structure.
  • a net could also be produced by means of an injection molding process.
  • the openings arise in any case directly in the production of the fabric. This feature highlights a network of structures in which a full-surface structure is subsequently perforated or slotted.
  • abrasive grains are applied to the lands and / or the nodes of the net.
  • the network included in such a loop network will hereinafter be referred to as a carrier network.
  • the abrasive grain coated surface of the carrier web is referred to as the first major surface.
  • the carrier web can also be coated on the second surface with abrasive grains.
  • the first main surface is essentially flat according to the invention. This is understood to mean that the first main surface has only slight deviations from an imaginary plane surface, in particular in the region of the nodal points. Furthermore, the webs are flat at least in part of their surface and are at least partially in the imaginary plane surface.
  • the plurality of nodes extend in the direction of the first main surface by less than 20%, preferably less than 10%, more preferably less than 5% of the thickness d beyond the surfaces of the webs.
  • d denotes the thickness of the webs perpendicular to the first main surface.
  • the first main surface has no protruding portions. The contact pressure per abrasive grain is consequently reduced, resulting in a more uniform sanding pattern.
  • the thickness of the carrier web perpendicular to the first major surface is less than 130%, preferably less than 120%, more preferably less than 110% of the thickness d.
  • the thickness of the carrier web perpendicular to the first major surface is less than 130%, preferably less than 120%, more preferably less than 110% of the thickness d.
  • the webs preferably have a greater extent parallel to the first main surface than perpendicular to the first main surface. In other words, the webs are wider than thick. On the one hand, this property causes an enlargement of the portion of the webs lying in the first main surface. On the other hand, during grinding, the twisting of the webs about their longitudinal direction is effectively prevented, which could be detrimental to the grinding result.
  • the cross sections of the webs in a plane perpendicular to the first main surface may, for example, have the shape of an ellipse, a circle flattened on two opposite sides, or a rectangle.
  • the extent of the webs parallel to the first main surface is at least 120%, preferably at least 150%, more preferably at least 180% of the extension of the webs perpendicular to the first main surface.
  • the webs within or parallel to the first main surface has a width of 0.1 mm to 5 mm, preferably from 0.3 to 2 mm, particularly preferably from 0.5 to 1 mm. This width thus determines the distance between two adjacent openings.
  • the webs have a thickness of 0.02 mm to 0.5 mm, preferably from 0.05 mm to 0.3 mm, particularly preferably from 0.15 mm to 0.25 mm, perpendicular to the first main surface.
  • the openings preferably have a passage size of from 0.2 mm to 5 mm, preferably from 0.5 mm to 3 mm, particularly preferably from 1 mm to 2 mm, within or parallel to the first main surface.
  • the passage size of an opening indicates the largest possible diameter of a spherical particle which can just pass through the opening.
  • the webs are preferably connected to one another at an angle in the range from 30 to 150 °, preferably from 60 to 120 °, particularly preferably from 80 to 100 °. For given widths and lengths of the webs in this angular range of the area fraction of the openings on the entire surface of the grinding network largest, so that there is an optimal cooling and / or dust extraction.
  • four webs are connected to each other at a node.
  • three or more than four webs are connected to one another at a node.
  • the carrier network has openings whose density is in the range from 5 to 500 per cm 2 , preferably from 10 to 350 per cm 2 , particularly preferably from 12 to 200 per cm 2 .
  • Such a density of the openings which would be difficult to achieve, for example, through the perforation of a film, gives excellent results, in particular during fine grinding.
  • the openings may for example be rectangular, trapezoidal, triangular or hexagonal or have any other polygonal shape. Of course, depending on the nature of the webs and the nodal points, they can also have other shapes, for example rounded off by rounding.
  • the openings are arranged regularly, in particular periodically, which facilitates the production. Of course, it is also conceivable and within the scope of the invention that the openings are arranged irregularly.
  • the carrier network has a basis weight between 10 g / m 2 and 200 g / m 2 , preferably between 50 g / m 2 and 150 g / m 2 , more preferably between 80 g / m 2 and 100 g / m 2 .
  • the carrier network has a thickness, in particular at the nodes, in the range of 0.02 to 0.5 mm, preferably from 0.05 to 0.3 mm, particularly preferably from 0.15 to 0.25 mm.
  • the carrier network comprises monofilaments. Most preferably, the monofilaments are extruded. According to another embodiment, the carrier network comprises multifilaments. Of course, combinations thereof are also within the scope of the invention.
  • the carrier network comprises an extruded net.
  • the carrier network may comprise an integrally extruded net.
  • Such networks per se are known to those skilled in the art, for example DE 35 08 941 A1 .
  • An extruded net has a greater stiffness compared to known equal basis weight woven or knitted abrasive backing, which for some applications, e.g. As for packaging, reinforcements for plasters or filtration, is very beneficial.
  • known woven or knitted abrasive carriers must first be subjected to a complex impregnation process in order to achieve the rigidity desired for such applications.
  • Extruded nets are a cost-effective and easy to assemble mass-produced.
  • the dimensions and orientation of the webs and the openings can be chosen arbitrarily, making them very flexible and can be used as required.
  • the carrier web may be made by knitting, weaving, braiding, knitting, crocheting, sewing, embroidering, batting or knitting from thread or strip strands.
  • Each of the strands can be a monofilament or a multifilament be.

  • the portions of the strands extending between two adjacent nodes are referred to as lands in the terminology used herein.
  • the strands can be movable against each other at the points of contact, that is to say at the nodal points.
  • an embodiment is preferred in which the strands are firmly connected to one another at the junctions, for example by welding. In this way, a carrier net is provided which is more resistant to the stress of grinding because the strands can not slip against each other.
  • the carrier network can also be produced by an injection molding process.
  • the carrier network is calendered.
  • the carrier web is calendered prior to the fixation of abrasive grains.
  • Such a calendered net is smoothed at the nodes and the webs and widened in a plane parallel to the first main surface, which increases the contact area to a workpiece to be machined and thus causes a more uniform grinding effect.

  • the abrasive grains are preferably fixed to the carrier network with the aid of a binder.

  • the abrasive grains and the binder are applied to at least a major portion of the first major surface, more preferably to the entire first major surface. This decreases in contrast to the approximately in US 2,984,052 illustrated point coating the pressure force per abrasive grain and thus produces a uniform Abschliff.
  • the openings in the carrier net are preferably substantially not closed with abrasive grains and binder. This leads to a high permeability to air and / or grinding dust, especially when using an active dust extraction.
  • the curing of the binder can also be carried out in a manner known to the person skilled in the art, for example by means of heat, drying or radiation.
  • abrasive grains are known minerals such as corundum, Blaubrand, zirconium corundum, silicon carbide, emery, ruby (garnet), flint, diamond or cubic boron nitride and mixtures thereof.
