  • the cutting edge is exerted when the pretensioning force is exerted a radial between the cutting tool and the anvil roll Distance of less than about 500 microns to the at least one support surface having.
  • a particularly reliable cut of high-strength materials preferred embodiment ensured that the Cut when pretensioning, d. H. in the loaded state the rotary cutter, a radial distance of less has about 100 microns to the support surface.
  • the at least one support ring is made of hard metal at least in the area of the support surface. at such an embodiment is not subject to the cutting edge and the assigned support surface is still used to support the cutting tool support ring used in relation to the anvil roller noticeable wear, so that the rotary cutter even when exercising high pre-tensioning forces through a special long service life.
  • the support ring can have a hard metal surface coating exhibit.
  • the at least a support ring is made essentially entirely of hard metal.
  • the cutting support which is preferably made entirely of hard metal can be designed, for example, in the form of a cutting plate is held on the anvil roll, its curvature at the curvature the anvil roller is adapted.
  • the cutting support is a support sleeve comprises a base body of the anvil roll in the circumferential direction surrounds.
  • the cutting support held positively on the base of the anvil roll, so that the Cutting support also reliable for high mechanical loads can withstand.
  • the cutting support is integral with the anvil roller is connected and can thus be produced as a single component is.
  • Such an embodiment is particularly of Advantage if the cutting support has a surface coating Has carbide.
  • the rotary cutting device preferably comprises two made of hard metal Manufactured support rings, each rotatably on the cutting tool are held and hold the cutting edge between them.
  • the support rings are integrally connected to the cutting tool are and thus form a single component, it being particularly
  • the advantage is if the support rings have a hard metal surface coating exhibit.
  • the hard metal used is preferably a powder metallurgy one Sintered metal is used, for example a sintered material a metallic hard material based on tungsten and a binding agent based on cobalt.
  • a carbide for the cutting edge and the cutting support are used, whose hard phase consists essentially of titanium carbide and / or titanium nitride.
  • Such carbides containing titanium carbide are known under the name "Cermet".
  • the hard metal preferably has a hardness of more than about 700 HV (Vickers hardness).
  • the rotary cutting device includes a machine frame 12 two vertically aligned stands 14, 16 on a base plate 18 held and at their free ends via a crossbar 20 together are connected. Between the stands 14, 16 of the machine frame 12 are in known rotary bearings 22, 23 and 24, 25th an anvil roller 28 or a cutting tool in the form of a cutting roller 30 rotatably mounted.
  • the supports 14 and 15 known per se and therefore only schematically in the drawing shown adjusting devices 32, 34, the cutting roller 30 in an adjustment direction 36 which is parallel to the extension of the stand 14, 16 runs, are adjusted.
  • Rotary bearings 24 and 25 are supported by the adjustment devices 34 and 36 and one each at the free end region of the stand 14 or 16 held biasing device 38 on one of the cross-beam 20 supported abutments 40 from.
  • the pretensioner 38 can the cutting roller 30 with an adjustable biasing force be applied in the direction of the anvil roller 28.
  • the anvil roller 28 is freely rotatable about an axis of rotation 42 and includes a cylindrical base body 44, on the end faces of which shaft stub 46, 48 are attached, which are mounted in the pivot bearings 22 and 23, respectively are.
  • the anvil roller 28 includes the base body 44 circumferentially surrounding support sleeve 50, the form-fitting connected to the base body 44 and from a powder metallurgy manufactured carbide, its hard phase essentially from tungsten carbide (WC) and its binder essentially is made of cobalt.
  • the cutting roller 30 is held in a rotationally fixed manner on a tool shaft 52, which is freely rotatable about an axis of rotation 54 in the pivot bearings 24 and 25 is mounted, with a drive stub 56 through the rotary bearing 24 extends through.
  • a drive stub 56 is the cutting roller 30 by means of known and therefore not in the drawing Motor and gear means shown can be driven in rotation.
  • the cylindrical roller 30 has in the area of its Cylinder jacket 58 is essentially wedge-shaped in cross section configured cutting edge 60, which extends both in the circumferential direction of the Cylinder jacket 58 and in the axial direction based on the axis of rotation 54 of the cutting roller 30 extends and a self-contained Curve forms.
  • support rings 62, 64 on the end faces of the cutting roller 30 held non-rotatably. These are coaxial to the cutting edge 30 on both sides Axis of rotation 54 of the cutting roller 30 arranged and each have a Support surface 66, which is aligned cylindrically to the axis of rotation 54 and on both sides of the cutting edge 60 on the support sleeve 50 of the anvil roll 28 rest.
  • the pretensioning devices 38 can be used Cutting roller 30 are clamped with the anvil roller 28, whereby the cutting roller 30 by means of the support rings 62, 64 on the anvil roller 28 supports.

  • the cutting edge 60 and the support rings 62, 64 are made made of the same carbide that is used in the manufacture of the Support sleeve 50 is used. Because the carbide is only a relative has low breaking strength, is 60 in for the cutting edge unloaded state of the rotary cutting machine 10, d. H. in one State in which no pretensioning force acts on the cutting roller 30, a smaller radial extension is provided based on the Axis of rotation 54 of the cutting roller 30 than for the support surface 66. This will clear from the enlarged view in Figure 3.
  • Im unloaded State thus shows the tip 68 of the cutting edge 60 in the radial direction a distance d to the support surface 66.
  • This distance is preferably less than 500 ⁇ m, especially less than 100 ⁇ m, for example about 80 ⁇ m.
  • the size of the distance d becomes dependent the modulus of elasticity of the support rings 62, 64 selected such that the cutting tip 68 practically touches the surface of the support sleeve 50, if when cutting the material using the pretensioning devices 38 a biasing force on the cutting roller 30 in the direction the anvil roller 28 is exercised.
  • the support rings made of hard metal 62, 64 when loaded with the preload force of a deformation in the radial direction subject to so that their radial extension based on the Axis of rotation 54 of the cutting roller 30 is reduced.
  • the one in the unloaded State of the rotary cutting device 10 present distance d between the cutting tip 68 and the support surface 60 is chosen such that in the loaded state due to the radial deformation of the Back-up rings 62, 64 is practically compensated for, but ensured is that the cutting tip 68 in even when loaded radial direction does not protrude beyond the support surface 66, so that a Damage to the carbide cutting edge 60 during the operation of the Rotary cutting device 10 is reliably prevented.
  • the size of the radial distance d between the cutting tip 68 and the support surface 66 is thus dependent on the modulus of elasticity of the used for the production of the support rings 62, 64 Carbide material.
