Definitions

  • the invention relates to a grinding tool for grinding an engine block, comprising a base body, which comprises a central coupling area for connecting the base body to a rotary drive of a grinding machine, the base body being essentially rotationally symmetrical with respect to an axis of rotation, a grinding surface which is arranged on the base body and extends at least over an outer annular zone of the base body, at least one supply for a cooling fluid, and a substantially circular cover plate, which is arranged substantially normal to the axis of rotation and with the formation of an axial gap on the base body, the axial gap being in fluid communication with the at least one is a feed and the abrasive coating, so that a cooling fluid supplied via the at least one feed can be directed via the axial gap to the abrasive coating.
  • the invention further relates to an arrangement of such a grinding tool and an HSK receptacle connected thereto at least via the central coupling area of the base body.
  • grinding tools for grinding engine blocks are known per se from the prior art.
  • the grinding process used is also known as “micro milling” or “smear grinding”.
  • the material subjected to the grinding process is removed and “lubricated” via the microporosity of the surface to be ground.
  • the grinding tools are often cooled by means of a cooling fluid, a cooling fluid supplied via a feed being led to the grinding lining via an axial gap.
  • the cover plate is positioned at a distance from the base body, which results in a cylindrical gap between the cover plate and the base body, over which the cooling fluid is distributed.
  • the EP 1 859 904 A1 proposes to arrange a flange on a grinding tool which forms a gap with a base body of the grinding tool. This gap is in fluid communication with a supply for cooling fluid and serves to direct the cooling fluid more effectively to a grinding surface of the grinding tool.
  • the DE10 2008 025 120 B3 proposes a split grinding wheel, which consists of two part wheels that can be rotated and fixed against each other.
  • the dividing disks have spacing ramps on the basis of which the spacing of the dividing disks changes when they are rotated relative to one another. Due to the rotation of the dividing disks relative to one another, gaps arise between the dividing disks, which can be used to conduct cooling fluid.
  • the object of the present invention is therefore to improve the service life of the grinding tool and the surface quality of the surface of the engine blocks to be processed with the grinding tool compared to the prior art, and an arrangement of an improved grinding tool compared to the prior art and at least above the central one Specify the coupling area of the base body associated HSK recording.
  • the base body and the cover plate have an inclined surface which adjoins the abrasive coating, the inclined surfaces contacting each other in regions, and that second channels are arranged on the inclined surface for the targeted conduction of the cooling fluid, and that the second Channels are arranged offset to the first channels, and / or more second channels are provided as first channels.
  • the cooling fluid can thus be directed in a targeted manner via first and second channels from the at least one feed to the abrasive coating, as a result of which a more uniform and controlled distribution of the cooling fluid is possible.
  • sanded material can be removed more efficiently. Overall, this leads to an approximately 30% longer service life compared to the prior art.
  • protection is also sought for an arrangement comprising a grinding tool according to the invention and an HSK receptacle connected to it at least via the central coupling area of the base body.
  • the Figures 1 , 2nd and 3a show an arrangement 25 of a grinding tool 1 for grinding an engine block and an HSK receptacle 23.
  • the grinding tool 1 comprises a base body 2, which has a central coupling area 3 for connecting the base body 2 to a rotary drive 4 of a grinding machine 5 (in FIG Figure 3a indicated by dashed lines), wherein the base body 2 is essentially rotationally symmetrical with respect to an axis of rotation 6.
  • the central coupling area 3 is designed such that the grinding tool 1 can be connected to an HSK receptacle 23.
  • the grinding tool 1 further comprises an abrasive coating 7, which extends at least over an outer annular zone 8 of the base body 2, at least one feed 9 for a cooling fluid 10, and an essentially circular cover plate 11, which is essentially normal to the axis of rotation 6 and with the formation of a Axial gap 12 is arranged on the base body 2, the axial gap 12 being in fluid communication with the at least one feed line 9 and the abrasive coating 7, so that a cooling fluid 10 supplied via the at least one feed line 9 is conducted via the axial gap 12 to the abrasive coating 7 can (compare Figure 3a ).
  • the circular ring zone 8 of the base body 2 is oriented essentially normal to the axis of rotation 6.
  • first channels 15 are arranged for the targeted conduction of the cooling fluid 10 from the at least one feed 9 to the abrasive coating 7.
  • first channels 15 on a surface 14 of the cover plate 11 facing the base body 2 for the targeted routing of the cooling fluid 10 from the at least one feed 9 to the abrasive coating 7.
  • first channels 15 for the targeted conduction of the cooling fluid 10 from the at least one on both the surface 13 of the base body 2 facing the cover plate 11 and the surface 14 facing the base body 2 Feed 9 to the abrasive coating 7 are arranged.
  • the feed 9 for the cooling fluid 10 runs essentially parallel to the axis of rotation 6 or in the axial direction 29, and is designed as a bore in the base body 2. This feed 9 can continue in the HSK receptacle 23 in the form of an opening 33.
  • the cover plate 11, the base body 2 and the HSK receptacle 23 are detachably connected to one another via connecting means 24 in the form of screws.
  • the screws penetrate recesses 30 in the cover plate 11 and recesses 31 in the base body 2 and are mounted in bores 32 in the HSK receptacle 23.

  • the surface 13 of the base body 2 facing the cover plate 11 and the surface 14 of the cover plate 11 facing the base body 2 make contact in regions, specifically at the points at which no first channels 15 are provided.
  • the base body 2 and the cover plate 11 each have an inclined surface 17, 18 which adjoins the abrasive coating 7, the inclined surfaces 17, 18 making contact in some areas.
  • Second channels 19 are arranged on the inclined surface 17 for the targeted conduction of the cooling fluid 10.
  • second channels 19 can be arranged for the targeted conduction of the cooling fluid 10.
  • third channels 20 are arranged for the targeted conduction of the cooling fluid 10, the third channels 20 being connected to the second channels 19.
  • An annular channel 26 is arranged between the base body 2 and the cover plate 11 for the targeted conduction of the cooling fluid 10.
  • a cooling fluid 10 supplied in the axial direction 29 is conducted radially via the first channels 15 in the direction of the outer edge 21 of the base body 2, reaches the annular channel 26, from there into the second channels 19 and finally into the third channels 20, which are arranged in the abrasive coating 7.
  • the outer annular zone 8 of the base body 2 is shown in detail.
  • the abrasive coating 7 arranged in this circular ring zone 8 on the base body 2 comprises diamonds, is galvanically connected to the base body 2, and has a thickness 22 of 0.1 mm to 1 mm, preferably approximately 0.3 mm.
  • the abrasive coating is not only oriented substantially normal to the axis of rotation 6, but also encloses part of the outer edge 21 of the base body 2.
  • the Figures 4a and 4b details of the cooling fluid distribution system can be found: Starting from the feed 9, the first channels 15 run outward in a substantially radial direction 16. The channels 15 are each at the same angular distance from one another.
  • the first channels 15 open into the annular channel 26, and the annular channel 26 is formed by a cavity between a partial surface 27 arranged on the base body 2 and a partial surface 28 arranged on the cover plate 11 (see also Figure 5 ).
