  • Publication number: 20240066614
    Abstract: A milling tool includes a tool head and an exchangeable cutter carrier. The tool head can be coupled to a tool holder, and the cutter carrier includes a plurality of cutters distributed around its circumference, each having a front facing face cutter and a peripheral cutter extending at an angle thereto. In this case, the cutter carrier, including the cutters, has a thickness of at most ten mm, in particular at most six mm, for a diameter of at least fifty mm.

  • Patent number: 11583946
    Abstract: A machine reaming tool includes a base body with a plurality of insert receivers with cutting inserts that are inserted therein. The cutting inserts are inserted into insert receivers that each form a linear guide of the cutting inserts in a direction orthogonal to a rotation axis of the machine reaming tool. The linear guide is a prismatic sliding guide such as a dovetail guide. In particular, the dovetail guide is designed asymmetrically.

  • Publication number: 20180169779
    Abstract: A machine reaming tool includes a shank and an interchangeable head assembled on the shank. The interchangeable head on a side that faces the shank includes at least one head groove and at least one head ridge. The shank on a side that faces the interchangeable head includes at least one shank groove and at least one shank ridge. In the assembled condition, the at least one head groove engages into the at least one shank ridge and the at least one shank groove engages into the at least one head ridge.

  • Patent number: 7748934
    Abstract: A machine reaming tool includes a reaming head or interchangeable head (1) and a shaft (2), wherein the interchangeable head (1) is of one piece and may be exchanged, and in an axial direction and at each location, thus including means for the exchange adaptation, is thinner than a maximal thickness hmax, wherein this maximal thickness hmax is computed in millimeters from a diameter D1 of the interchangeable head in millimeters as hmax=6 mm+(1/10)·(D1?12 mm). On account of this, a guide portion (18) for cutters of the reaming head (1) becomes very much shorter than usual, but despite this ensures an adequate quality of machining. In a preferred embodiment of the invention, the interchangeable head (1) in a plane shaft-side end-face (15) comprises cutout (11) for the centering fastening on the shaft (2).

On account of this, a guide portion (18) for cutters of the reaming head (1) becomes very much shorter than usual, but despite this ensures an adequate quality of machining. In a preferred embodiment of the invention, the interchangeable head (1) in a plane shaft-side end-face side end-face (15) comprises cutout (11) for the centring fastening on the shaft (2).
