Definitions

  • the invention relates to a method for grinding of cutting tools.
  • Flap discs are generally not used for grinding cutting tools; they are typically used for paint stripping and rust removal.
  • Cup wheels are designed as a straight truncated cone, being ground at the edge of the large base top.
  • cup wheels with straight and oblique pot Both types of cup wheels have an inner recess.
  • the cup wheel with oblique pot is designed as a hollow truncated cone inside.
  • An abrasive coating is arranged at the base edge.
  • the cup wheel with a straight pot is also hollow inside and thus has a U-shaped cross-section, wherein the abrasive coating is arranged on the end sides of the U-legs.
  • Both disc types are rotationally symmetrical, the axis of symmetry being the axis of rotation.
  • the grinding edge can have various shapes.
  • a disadvantage of cup wheels is a long adjustment and a 180 ° rotation of the workpiece when sanding points must be grinded with each opposite on a cup wheel. Due to the disc geometry, a machining process is usually limited to the use of a single grinding wheel; Workpiece tension or machine parts would otherwise collide with the disk bodies.
  • Peripheral disks also called circumferential disks
  • An undercut is difficult to carry out due to the orientation of the abrasive coating to the disk body.
  • Concave radii can only be ground up to a quarter circle at most.
  • Profile discs have instead of a parallel to the axis of rotation extending, circumferential disc edge a conically converging disc edge with a rounded (toric) tip. Only with the torus profile is sanded, whereby a relief can be made. The life of the precise Torusprofils is very limited, a precise dressing of these discs is not possible on the grinding machine.
  • a grinding pin is generally formed analogous to a milling cutter which can be clamped in a chuck, an abrasive coating being arranged instead of the milling cutters.
  • the object of the invention is to provide a method for grinding of cutting tools, with or with the arbitrary concave and convex profiles can be ground with one and the same grinding wheel, wherein a dressing grinding a grinding wheel used for grinding already on the grinding of the tool used machine tool should be possible.
  • the circumference of the grinding wheel is designed as a circumferential ridge with roof sides converging on it and each having an abrasive coating.
  • Concave radii of a surface contour area of the cutting tool are with the ridge and / or in each case with one of the roof sides and all convex contour areas are each sandable with one of the two sides of the roof.
  • the convex surface contour areas could also be ground with the ridge; However, it is more precise and faster with one of the roof sides.
  • the grinding wheel can be characterized as a peripheral disk, in which the peripheral side provided with an abrasive coating is no longer a circular cylinder jacket outer side, but now two peripheral sides, an angle in cross-section, analogous to a roof ridge converge.
  • the abrasive wheel is coated with diamond or cubic boron nitride abrasive material; Of course, other abrasive ingredients may be used within the scope of the invention.
  • Cutting tools are mainly, but not limited to, profile exchangeable plates or profiled rotating tools.
  • the symmetry axis of the grinding wheel is at the same time its axis of rotation.
  • the grinding wheel will be formed as a double cone wheel (V-shaped grinding wheel), wherein both cone axes coincide and form the axis of rotation.
  • the small area of each cone can now be a plane perpendicular to the axis of rotation; it does not have to be.
  • the two surfaces can be flat, with each other mirror-image or different curvature outwards or inwards formed.
  • the thickness of the grinding wheel depends, apart from mechanical stability requirements, on the surface profile radii to be ground or on the depth and the width of the profile pockets of the tool to be ground.
  • the Doppelkonusmantel vomit or roof sides will allow to converge at an angle smaller than 90 °, preferably you will choose this roof ridge angle typically with 60 °; Of course, smaller angles are possible, in particular select smaller 30 °.
  • the Roof ridge angle is selected for collision reasons about 10 ° smaller than the smallest angle of concave surface contour areas to be ground. Within this limit, the angle is chosen as large as possible in order to obtain maximum stability.
  • This stability includes, among other things, the mechanical stability of the grinding wheel and a geometrical stability of the roof ridge or of the torus resulting from wear.
  • Sanding is now done with one of the roof sides (cone shell sides) and / or with the roof ridge (top). Thanks to the angular orientation of the sanding pad to the disk body and thanks to the slender disk geometry, an undercut can also be created. The grinding wheel thickness and the roof ridge angle determine how deep and how narrow an undercut can be made.
  • the tip is usually very sharp after dressing. When sanded with it, it wears off and acts like a profile disc with a rounded tip. Although the sharp tip is used up quickly, it can also be produced again quickly with a dressing wheel already located on the same tool grinding machine. The slightly worn roof ridge is then torus-like with a very small torus radius. Because of this very small dimension deviations from a pointed geometry or the ideal torus in absolute measure are now very small and therefore tolerable. Compared to a profile grinding wheel, another grinding process is carried out with the grinding wheel according to the invention: not only with the tip, but also with the tip. H. mainly ground with the converging roof sides.
  • the grinding wheels have a typical wheel diameter of 300 mm. This relatively large radius is chosen to be able to grind flat surfaces.
  • any concave and convex profiles can be ground with the double cone disk, whereby concave radii with the point and straight lines in concave surface profiles of the cutting tool as well as all convex profiles with one of the two surfaces are ground.
  • This very advantageous grinding technique remains on surfaces, as given in particular in pot or peripheral disk, received:
  • the straight-disk profile of the double cone disk is easy to dress.
  • the flat roof sides have a long service life in the grinding process and can be used to improve the surface quality oscillating.
  • a grinding machine with such a double cone disk provides good workpiece accessibility, no problems with clamping devices and small machine paths.
  • the assembly of the machine with several discs (for example coarse-grained for roughing and fine-grained for finishing) is possible without collision.
  • the use of different discs for roughing results in a higher erosion performance and allows a more stable production process as a result of sparing the discs, in particular the slices.
  • the discs must now be dressed less and less often. It can also be followed by polishing cuts in the same machining program, which only serve to improve the surface quality with minimal abrasion.
  • the polishing process benefits from the grinding process proposed here, since fine-grain slices with grain sizes in the range of a few thousandths of a millimeter tolerate only the smallest of cuts. Very accurate wheel geometries and equally accurate tool geometries prior to the polishing operation are required.
  • the in the FIGS. 1 to 3 illustrated grinding wheel 1 has on the disc circumference (disc sheath) two trained as roof sides disc edge sides 3a and 3b, which converge to a circumferential ridge 5 .
  • the two roof sides 3a and 3b collide at a ridge angle ⁇ .
  • the size of the ridge angle ⁇ depends on the surface contour to be ground. As a rule, ridge angle ⁇ is less than 90 °, typically 60 °.
  • the roof sides 3a and 3b are covered with an abrasive coating 7a and 7b, respectively.
  • a breakthrough 9 is present in order to attach the disc 1 on a mandrel of a grinding head, not shown, can.
  • the grinding wheel 1 is rotationally symmetrical about its axis of rotation 10 .
  • the axis of rotation 10 forms the axis of the aperture 9.
  • a plane in which the peripheral roof ridge 5 is located, also forms a plane of symmetry 12.
  • the plane of symmetry 12 defines together with one of the roof sides 3a and 3b and one of the side surfaces 19a and 19a mentioned below.
  • 19b a cone [ 19a-3a-12 and 19b-3b-12 ].
  • the grinding wheel 1 can thus also be referred to as a double cone disk, the axis of rotation 10 being identical to the cone axes.
  • FIGS. 4a to 4j is the respective relative position between a grinding workpiece 11 to be ground and the grinding wheel 1 shown at different surface contour areas.
  • FIG. 4a It is shown how an approximately plane, straight running surface contour area 13 can be ground with the roof side 3b of the grinding wheel 1.
  • the tool 11 to be ground will generally be moved. If an undercut 14 with a concave surface contour, as in FIG. 4b are indicated, ground, is worked with the roof ridge 5 of the grinding wheel 1 .
  • a grinding of a now following straight or convex surface contour area 15, as in Figure 4c is shown with the Roof side 3a ground.
  • a following on the surface portion 15 convex edge 17 is further ground with the roof side 3a ( FIG. 4d ).
  • the approximately flat surface area 18 following the edge 17 is further ground with the roof side 3 a ( Figure 4e ).
  • the tool 11 is displaced and with the same roof side 3 a a flat (or convexly curved) surface area 20 (FIG. FIG. 4f ) ground.
  • the relief surface 21 having a concave surface area is made with the roof ridge 5 (FIG. Figure 4g ).
  • the following approximately straight surface region 22 of the relief cut is then connected to the roof side 3b ( FIG. Figure 4h ) and then also the following edge 23 ( FIG. 4i ) ground.
  • the already ground surface area 18 could, as in FIG. 4j shown again reground with the roof side 3b , in order to obtain a good transition from the edge 23 to the surface region 18 .
  • the surface contour areas 14 and 15 as well as 21 and 22 represent a relief section.
  • a plurality of grinding wheels are generally used for grinding tools.
  • a Abrichtschleiffraction 30 used to dress the grinding wheel 1 , ie to grind the sides of the roof after a longer grinding operation and to sharpen the roof ridge.
  • Abrichtschleiffraction and one or more grinding wheels 1 are located on the same machine tool. That is, a dressing of the grinding wheels can be made without removing the grinding wheels from the machine tool, resulting in a large time gain.
  • the grinding wheel can now as in the FIGS. 1 to 3 can be formed as a disc with mutually parallel side surfaces 19a and 19b . But it can also in addition to outwardly slightly cambered side surfaces, as mentioned above, also cambered inwardly offset side surfaces or even and parallel to each other, as in a FIG. 6 shown grinding wheel 32 are used.
  • a base 34 of the roof sides 36a and 35b is wider than the thickness d of the grinding wheel 32.
  • An advantage of this grinding wheel 32 over the grinding wheel 1 is the smaller dimension and thus a smaller mass, which changes rapidly the rotational frequency allows. However, to achieve a uniform rotational speed during grinding, higher speed control and constant maintenance requirements are required due to the lower mass.
