Abstract

A method for producing a milling disc with embedded insets of hard metal, ceramics or other similar hard materials. The milling disc has a centrical bore in the base body of the disc. The tips of the insets protrude over the circumference of the disc body. The invention also relates to a milling disc produced according to the method wherein a powdery sintered metal material is filled into the recess of a mold pertaining to a compression molding die, and the mold matches the outer contour of the disc base body. Pre-fabricated insets are inserted into the sintered metal material and are positioned in the mold of the compression molding die. A green compact is subsequently pressed in the compression molding die and then taken out of the compression molding die. The green compact is sintered with the pressed insets and is subjected to hardening and/or surface treatment, if required. According to the milling disc, the resistance of the insets in the disc base body and the properties of the disc base body are improved.
