Abstract
A method for producing a ceramically bonded grinding tool includes, in chronological order, mixing a grinding agent, an inorganic binding agent, and an organic binding agent. The grinding agent, the inorganic binding agent, and the organic binding agent are pre-pressed in a cold-pressing step to form a cold-pressed green body. The cold-pressed green body is pressed in a hot-pressing step to form a hot-pressed green body. The hot-pressed green body is burned in a burning step to form a grinding tool blank. The organic binding agent is at least partly burned off during the burning step, and the grinding tool blank is post-processed in a subsequent step to form the grinding tool, into which the grinding agent is incorporated.
Claims19
A method for producing a ceramically bonded grinding tool, in particular a honing ring, comprising the following method steps, to be carried out in chronological order:
- in a first method step, at least one abrasive, in particular corundum, SiC, aluminum oxide, and/or a superabrasive, at least one inorganic bonding material, in particular formed as a low-temperature baking bond, and at least one organic bonding material, in particular in the form of epoxy resin, are provided and blended,
- the at least one abrasive, the at least one inorganic bonding material and the at least one organic bonding material are pre-pressed in a cold-pressing step to form a cold-pressed green body,
- the cold-pressed green body is pressed in a hot-pressing step to form a hot-pressed green body,
- the hot-pressed green body is fired in a firing step to form a grinding tool blank, in particular a honing ring blank, wherein the at least one organic bonding material is at least partly burned off during the firing step, and
- the grinding tool blank is post-processed in a subsequent method step to form the grinding tool, in which abrasive is embedded.
A ceramically bonded grinding tool, in particular a honing ring,
- comprising
- a main body and
- at least one abrasive that is embedded in the main body by means of at least one inorganic bonding material,
- wherein
- a grain volume of the abrasive is in the range between 50 vol. % and 65 vol. %, in particular between 53 vol. % and 58 vol. %, and
- a bond volume of a bonding material is in the range between 10 vol. % and 35 vol. %, in particular between 18 vol. % and 26 vol. %,
- of the grinding tool, wherein the grain volume and the bond volume together amount to at most 100 vol. % of the grinding tool.
