Definitions

  • the invention relates to a grinding wheel and a ring system according to the preamble of claim 1.
  • EP 0 112 220 A shows a device according to the preamble of the independent main claim.
  • the invention has for its object to improve the cooling and lubrication even in previously used grinding wheels without major conversion effort. This is achieved by the features of claim 1.
  • the cooling and. Lubricating medium is taken up by a specially attached ring system on the grinding wheel, compressed and transported to the required starting points during the grinding process. Through this coolant and lubricant control system, the medium can be brought more targeted to the desired starting points.
  • the abrasive article is cooled more uniformly and to a greater extent. As a result, increased grinding performance and improved quality of the workpiece and longer service life of the grinding tools are achieved.
  • the ring for media absorption can be produced from a wide variety of materials and in a wide variety of working or processing types (for example, machining, forming technology, casting technology).
  • This ring with its central opening serves to create a cavity and thus the medium introduction into the inner body of the grinding wheel construction.
  • the ring for media pickup can be made in a split and undivided configuration and is connected and fixed by means of a mounted in the grinding wheel groove with the abrasive body.
  • the media-receiving ring may include bores that bring the cooling and lubricating media in concentrated form to the desired point of application on the inside of the abrasive wheel.
  • the ring for media guidance and medium compression can be produced from a wide variety of materials and in a wide variety of working or processing types (eg machining, forming technology, belt technology).
  • the ring for media guide and medium compression can be made in a split and undivided configuration and is connected and fixed by means of a mounted in the grinding wheel groove with the grinding wheel. This ring is also located on the inside of the grinding wheel and serves with its recesses of the medium compression. In order to the peripheral speed of the grinding wheel is imposed on the cooling and lubricating medium.
  • the compressed medium is either transported via holes in the grinding wheel to the outside of the grinding wheel to the ring for controlling the medium outlet and thus to the point of use or brought through holes in the grinding wheel and in the abrasive coating directly to the point of use.
  • the ring for controlling the medium outlet can be produced from a wide variety of materials and in a wide variety of working or processing types (for example, metal working, casting technology).
  • the ring for controlling the medium outlet can be made in a divided and undivided configuration and is connected and fixed by means of a groove mounted in the abrasive body with the grinding wheel. With this ring, the compressed medium is brought circumferentially on the outside of the grinding wheel to the desired starting point.
  • the known grinding wheels already in use can be improved in new production and retrofitting without major conversion effort, especially with regard to improved loop properties, higher life, lower machine downtime, shorter processing time, higher repetition accuracy and less heating of the grinding wheel and the workpiece and higher surface quality of the workpiece become. Due to the higher lubricating and cooling effect it is achieved that no structural change occurs in processed materials.
  • the grinding wheel consisting of a carrier body (1) and an abrasive coating (2) with the built-in ring for media intake (3) through the central opening of the medium enters the grinding wheel.
  • the medium can also be guided via outlet openings (9) to the grinding point on the inside of the grinding wheel. All rings of the system are anchored in prefabricated grooves (8). Due to the centrifugal force of the rotating grinding wheel, the medium passes compressed through recesses, recesses or partitions (10) in the ring for medium guidance and medium compression concentrated to the contact surface on the abrasive coating and workpiece.
