  • Patent number: 11396056
    Abstract: A method for providing teeth on working gears by cutting, wherein the working gear and the cutting tool are driven in rotation at a predetermined speed ratio along axes oriented at an intersection angle. The flanks of the cutting teeth form edges having flank cutting sections arranged on the edges of a gap between two adjacent teeth and extend along a first contour line, and which as a result of an advance in the direction of the working gear engage in a cutting manner to produce teeth having a flank contour predetermined by the shape of the cutting edge. Each of the flank cutting sections is adjoined by a tip cutting section which extends along a second contour line in the region of the base of the cutting tooth gap, wherein the second contour line is curved such that at least partially rounded tooth tips are produced on the teeth.

  • Patent number: 11383341
    Abstract: A machine tool configured to attach multiple tools to a turret is provided to improve the efficiency of a tool exchanging operation and, thus, also the production efficiency. A control device determines whether an expired tool, which is a tool needs to be exchanged, is present among the tools held by the turret. The control device sets a tool exchanging position, which is a position within the movable range of a head section and is a position where the expired tool is exchanged with a new tool. If the control device determines that an expired tool is present, the control device causes a head section driving device to move the head and rotate the turret to position the expired tool at the tool exchanging position.

  • Patent number: 11370041
    Abstract: The present invention relates to a slanting-bed feed processing machine tool of a large propeller. The machine tool comprises a slanting column feed bed, a machine tool spindle, a workpiece rotary worktable, a large propeller and a bed feed mechanism. The present invention coordinates the geometrical relationship between the machine tool and the large propeller to ensure that the slanting column feed bed moves between two blades, thereby reducing the overhang length of the spindle. Different forms of workpiece rotary worktables and bed feed mechanisms are selected according to different slanting column feed beds. Four types of slanting column feed beds are designed, which can be selected, optimized and applied for different processing objects. The present invention enhances the processing stiffness of the spindle and solves the problem of poor processing quality of the large propeller caused by machine tool vibration.
