  • Publication number: 20220143713
    Abstract: Cutting insert for a tool for machining. The cutting insert is particularly suitable for grooving tools for grooving turning. The cutting insert has a chip breaker geometry in its cutting region, which enables both machining of full cuts and machining of partial cuts as well as machining of webs. In particular, due to the shape of a chip cavity provided in the cutting region and due to the presence of a negative chamfer, very short chips can be produced in all three machining variants, so that a high level of process reliability is ensured and long tool lives are made possible.

  • Publication number: 20170113248
    Abstract: The present invention relates to a method for coating a board of wood-based material, in particular a board of real wood, a plywood board or a board for parquet flooring, with a flowable plastics material. The method comprises applying the plastics material as a single, thick layer to the board of wood-based material (6) and creating an impressed structure by means of a material web (3) or a structure roller. After creating the impressed structure, the plastics material is cured to produce a wear resistant surface.

  • Publication number: 20060127194
    Abstract: The invention concerns a machining tool for chip removal, in particular a milling cutter, comprising a support (10) wherein is provided a housing (12) for a cutting element (14) equipped with a machining part (16) and a fixing part (18). The fixing part (18) includes a base part (20) which is placed in the housing (12) in receiving position (22) and which, when it its rotated into interlocking position (26) meshes beneath at least one retaining flange (26) of the housing (12), being thereby capable of being used with the cutting element (14) for chip removal matching. It is therefore possible to fix said cutting element without additional retaining means, such as a fixing screw or the like, its simple insertion into the housing and its interlocking position by rotation providing a reliable fixing method. Conversely, said cutting element can be released from its interlocked position and extracted from the housing hardly with very little force.

  • Patent number: 6139227
    Abstract: A holder for free-cutting machining tool inserts, especially for chiseling, piercing or cutting inserts, includes an essentially beam-like edge support (1) with a receiving pocket (5) constructed in its end for the blade edge inserts. Clamping jaws (9 and 11) define the narrow width of the receiving pocket (5). A slot (29) is configured in the blade edge support (1) forming a flexible pivot for moving one clamping jaw. An operating member (37) is provided for producing a clamping force in the area of the slot (29) on the movable clamping jaw (11). The operating member (37) is mounted in a bore (39) at some distance from the slot (29). The clamping force is transmitted to the movable clamping jaw (11) through a force transmission member (43) which is slidably guided in the blade edge support (1).
