Definitions

  • the invention relates to a tool for machining surfaces, in particular of walls, made of natural and artificial stone, which is suitable for use in a hand-held device, and a hand-held device with such a tool.
  • EP 1 321 233 A discloses a grinding tool (10) for machining natural and artificial stone surfaces, comprising a support plate (11); at least one cutting element (19) consisting of a support body made of hard metal (21), which is provided at least in a region of the cutting edges with a layer of polycrystalline diamond (PCD).
  • a grinding tool 10 for machining natural and artificial stone surfaces, comprising a support plate (11); at least one cutting element (19) consisting of a support body made of hard metal (21), which is provided at least in a region of the cutting edges with a layer of polycrystalline diamond (PCD).
  • PCD polycrystalline diamond
  • Tools for smoothing surfaces made of natural or artificial stone (eg concrete) as well as for the removal of materials such as plaster, paint, spatula, adhesive or flooring residues are known per se.
  • natural or artificial stone eg concrete
  • hand tools are practical, while for the processing of large floor areas usually relatively heavy, rolling floor equipment are used.
  • Both types of tool have in common that they usually have one or more plate-shaped tools, which are rotated by a drive motor in rotation.
  • cutting elements are fastened which, as part of the machining process, remove the topmost layer of the machined surface or projecting sections (eg concrete teeth) or coverings.
  • hand tools and handheld tools have significant differences. These are partly due to the different contact pressure of the tool types: While hand tools a maximum contact pressure of (converted) 20-40 kg is common, common ground devices often have a mass of 300-400 kg and exert a corresponding contact pressure on the machined floor space out. Accordingly, the tools for hand tools to achieve an optimal work result must be designed differently than tools for ground equipment. Secondly, the weight and dimensions of hand tool tools must not exceed a certain level in order to be practical with the handset. As a result, the design of the usable tools limits.
  • the company HTC Sweden AB offers z.
  • a grinding wheel "T-Rex Gold” for use in mobile equipment for tillage.
  • the tool is intended exclusively for removing adhesive or paint layers. It consists of a circular support plate, at its periphery a plurality of cutting elements in the form of cylinder segments are attached. The elements are attached to the carrier plate in such a way that the cutting edges are formed by the front-side termination of the cylinder jacket, that is to say in the form of a circular arc.
  • the cutting elements used so far are usually designed such that the machined material (in particular natural and artificial stone material) is crushed, which has a large dust development result. This necessarily requires an extraction system or requires the use of a wet grinding process.
  • the EP 1 321 233 A1 (Gerätebau Wiedtal Schützeichel KG) now shows a grinding tool as part of a floor grinding machine, which is suitable, inter alia, for the treatment of stone and artificial stone floors, with a rotatably drivable support plate and a tool support member arranged thereon, which is equipped with editing tools.
  • the machining tools consist of disc-shaped PCD elements. In addition to a longer service life, this choice of material has the result according to the description that the material to be processed is not or not significantly rubbed, but that it comes to a chipping.
  • the PCD elements may have different basic shapes and z. B. circular, semicircular or triangular.
  • the PCD elements are made of hard metal and, at least in the region of the cutting edges, have a layer of polycrystalline diamond sintered onto the hardmetal surface.
  • ground machines are not suitable for use in handheld devices or allow for this use due to the above-mentioned differences between ground machines and hand tools only a little efficient work.
  • T-Rex The already mentioned above company HTC Sweden offers under the name "T-Rex” and also for the removal of coatings (paint, lacquer, epoxy, etc.) to a grinding wheel for hand tools, which as a peripheral peripherally a series of virtually perpendicular to the surface of the Support plate standing disc-shaped diamond segments having.
  • the cutting edges are in turn formed by the curved segment edge.
  • the tool has a long service life and enables efficient removal of said coating materials.
  • the tool is not intended for the processing of natural and artificial stone, and its advantageous properties do not come into play in this application.
  • the object of the invention is therefore to provide a the technical field mentioned above, suitable for use in a hand tool, which tool is durable and which allows efficient processing of surfaces of natural and artificial stone with consistent quality.
  • inventive tool can also be achieved in handsets, that in the context of processing is not a trituration of the material, but that this rather eroded spanweise, so to speak, "planed away" is. The dust development can thus be greatly reduced. (Nevertheless, it is recommended in terms of worker protection to use a suction device.)
  • inventive tool is also suitable for use in wet processing.
  • the tool is basically suitable for use in commercially available handsets, especially in concrete hand grinders.
  • These devices usually include an electric motor for rotatably driving a workpiece holder to which the tool can be mounted in the center of the carrier plate.
  • the devices can be designed in various designs, in particular in the so-called “tower shape", in which the electric motor with its main axis is perpendicular to the substrate to be processed and handles are arranged on both sides of the engine, or in the form of an angle grinder, in which the electric motor with its main axis is parallel to the machined ground and its drive torque is deflected by a gear through 90 °.
  • the ratio between the axial extent of the cylinder segment (ie the height of the corresponding cylinder) and the radius of the cylinder segment is at least 0.8, preferably at least 1.0.
  • the cutting element is not merely a disk-like "blade", but a solid body over which the opposing forces occurring during the machining process can be reliably dissipated to the carrier plate.
  • the corresponding cylinder segment can be also secure to the support plate and has a high mechanical stability.
  • the thickness of the section of polycrystalline diamond (PCD) measured in the axial direction is advantageously at least 0.8 mm, preferably at least 1.2 mm. It is thus not just a PCD coating on a hard metal body, but a sintered on the support body PCD block. This ensures a long service life, ensures that the cutting edges are always formed completely from the PCD material even after prolonged use, and that the surface of the cutting elements interacting with the material to be processed always has such a smoothness that removed material (e.g. heated plastics, glue residues, paints, varnishes etc.) does not adhere to the cutting elements.
  • removed material e.g. heated plastics, glue residues, paints, varnishes etc.
  • the segment angle is advantageously 60-120 °, preferably about 90 °. It has been found that at such angles, there is an optimum combination of mechanical robustness with work efficiency. At angles smaller than 60 ° results in a reduced mechanical stability of the tool. At angles greater than 120 °, the processing efficiency decreases.
  • particularly suitable cylinder segments have in particular the shape of a quarter cylinder (segment angle about 90 °), a radius of 4 - 10 mm, in particular 6 - 8 mm, and an axial extent of 5 -12 mm, in particular 6 - 10 mm ,
  • the cutting element is arranged on the carrier plate such that a vertical projection of the cylinder axis on a base surface of the carrier plate is substantially tangential and that the two radial straight edges of the frontal PCD section have the same angle to the base.
  • the cylinder segment is thus mounted symmetrically on the support plate, and the working edge is formed by the two radial straight edges. Accordingly, the counteracting forces acting on the cutting element can be passed independently of their direction to the support plate, and the cutting element is loaded evenly over time.
  • the said arrangement also allows efficient and accurate work.
  • the cutting element may be arranged with its cylinder axis obliquely to the respective tangents on the support plate, d. H. the working edge is mainly formed by one of the two radial straight edges. If required, the cutting element can also be arranged asymmetrically on the support plate, d. H. the bisector of the segment angle is not perpendicular to the respective radius of the carrier plate.
  • the cutting element is arranged with its cylinder axis obliquely to a base surface of the support plate, such that the meeting point of the radial straight edges of the frontal PCD section forms the maximum elevation of the cutting element over the base.
  • the angle between the cylinder axis and the base is 3 - 45 °, preferably 10 - 30 °, in particular 15 - 25 °.
  • the angled arrangement ensures that the portion of the cutting edge furthest away from the carrier plate, which first comes into contact with the material to be processed in a surface treatment, is arranged posteriorly in the direction of rotation of the carrier plate, while the portion of the cutting edge adjoining the carrier plate protrudes in the direction of rotation lies. It results in a uniform working resistance and a uniform machining.
  • the specified angles allow the best possible work efficiency, secure attachment of the cutting elements on the support plate and a direct dissipation of adverse forces in the support plate.
  • the cylinder segment with its cylinder axis parallel to the base surface of the support plate or to choose a larger angle.
  • the dimensions of the cutting element and the desired orientation corresponding recess in which the cutting element attached over a large area, in particular soldered, can be.
  • Large area means that the cutting element is not only point or line-wise connected to the support plate, but that there is a flat connection point;
