Abstract
A grinding tool, such as a cutting disc, includes a matrix, in particular a sintered metal matrix, and diamonds embedded in the matrix. At least the majority of the diamonds are each assigned at least one wear-promoting particle. The at least one wear-promoting particle is likewise embedded in the matrix.
Claims16
A grinding tool, comprising a matrix, and diamonds embedded in the matrix, wherein:
- each of at least a majority of the diamonds has at least one wear-promoting particle associated therewith,
- the at least one wear-promoting particle is embedded in the matrix,
- the grinding tool has a grinding direction,
- the at least one wear-promoting particle is embedded in the matrix upstream of the diamond with which the at least one wear-promoting particle is associated in the grinding direction, and
- the grinding tool has a grinding contact surface which is towards an article to be ground in a condition of use, and
- the at least one wear-promoting particle is at a smaller spacing relative to the grinding contact surface in relation to the diamond with which the at least one wear-promoting particle is associated.

A grinding tool, comprising a matrix, and diamonds embedded in the matrix, wherein:
- each of at least a majority of the diamonds has at least one wear-inhibiting particle associated therewith,
- the at least one wear-inhibiting particle is embedded in the matrix,
- the grinding tool has a grinding direction,
- the at least one wear-inhibiting particle is embedded in the matrix downstream of the diamond with which the at least one wear-inhibiting particle is associated in the grinding direction, and
- the grinding tool has a grinding contact surface which is towards an article to be ground in a condition of use, and
- the at least one wear-inhibiting particle is at a greater spacing relative to the grinding contact surface in relation to the diamond with which the at least one wear-inhibiting particle is associated.
