Method for producing a milling disc and milling disc produced according to the inventive method

In a method for producing a milling disk with embedded inserts made of a hard alloy, a ceramic material, or a similar hard material, which has a centered bore in a base body of a disk and wherein tips of the inserts project at a circumference of the base body of the disk, the improvement comprising:

• filling a pulverulent metal sintering material into a receptacle (A1, A2, A3) of a mold (W) of a compacting tool (W, UST, BST, OST) which is matched to outer contours of the base body of the disk (11), placing prefabricated inserts (HMS) into a poured-in metal sintering material and in the mold (W) of the compacting tool (W, UST, BST, OST),
• after introducing the metal sintering material and positioning the inserts (HMS) in the compacting tool (W, UST, BST, OST) pressing in a green compact (GL), and
• removing the green compact (GL) from the compacting tool (W, UST, BST, OST) with the inserts (HMS) pressed into the green compact (GL) and, if required, afterwards at least one of hardening and surface treating the green compact (GL), and a molybdenum-alloy sintering material is employed as the metal sintering material, and the green compact (GL) is sintered at approximately 1200 to 1300° C. in a protective gas atmosphere for approximately 60 to 90 minutes.
