The tool base (25) is provided for fixing one or more tools. A tool housing (26) with milling head (27) is provided, the tool housing (26) being displaceable relative to the workpiece blank (K1) held in the turning machine (22) and the milling head (27) is mounted to rotate about a milling head axis (B3).

Abstract: A method for producing a drive shaft of a food processor, the drive shaft having an end-side, splined-shaft-like toothing that is movable into positively locking engagement with a complementarily formed clutch. The method includes producing the toothing by machining the drive shaft with a cylindrical milling cutter, wherein the cylindrical milling cutter engages with the drive shaft from a radial direction with respect to a longitudinal axis of the drive shaft; and positioning an axis of rotation of the cylindrical milling cutter cross-wise relative to the longitudinal axis of the drive shaft, wherein the axis of rotation of the cylindrical milling cutter is at an incline relative to the longitudinal axis of the drive shaft so that the axis of rotation and the longitudinal axis draw an angle of less than 90°.

Abstract: The invention relates to a device (20) comprising a workpiece spindle (21) for receiving a gear wheel (25), a tool spindle (29) for receiving a tool and several drives (X, Y, Z, B, C, A1) for machining the gear wheel in individual divisions. According to the invention, one tooth gap of the gear wheel is machined and then the tool is displaced in relation to the gear wheel in order to remove the tool from the tooth gap. The gear wheel is then rotated by a division and the tool is placed against the wheel again to machine another tooth gap. One of the drives (C) can be controlled in such a way that the relative displacement involves a tilting displacement, which modifies the relative angle between the tool and the gear wheel, the tilting displacement being co-ordinated with the displacement of a division.

Abstract: Bevel gear cutting machine for chamfering and/or deburring edges on the teeth of a bevel gear. The gear-cutting machine comprises a workpiece spindle, which receives the bevel gear coaxially of a spindle axis. Furthermore, a deburring spindle is provided for the receiving of a deburring tool and several numerically controllable axes are given. A deburring blade head with several blade cutter-like blade inserts serves as deburring tool, whereby the blade inserts are insertable in recesses of the deburring blade head essentially radially oriented to a deburring spindle axis (E) and comprise edges for chamfering and/or deburring.

Abstract: In forming a helical gear by grinding with a grindstone, the modification accuracy of crowing etc. is improved in such a way that the inequality .beta.>.gamma. c is established wherein .beta. is the helix angle of the helical gear to be ground and .gamma. c is the inclination angle of the grindstone, and the profile of the grindstone is designed to have a vertical angle which is equal to the inclination angle (.gamma. c)of the grindstone.

Abstract: The production of differential speed reduction apparatus, which uses a double-toothed gear including face cams having tooth profiles uniquely generated to secure efficient speed reduction. The speed reduction apparatus includes an input shaft carrying the double-toothed gear, a slant shaft wobbling in association with the rotation of the input shaft, a stationary face gear engageable with the face cams, a movable face gear secured to an output shaft, wherein the stationary face gear and the movable face gear have a roller-like or a convex-face contour.

Abstract: A gear cutter is provided as an accessory to a milling machine. A single gear cutting blade makes successive passes across a continuously rotating gear blank to cut a desired number of gear teeth. The cycle time of the cutting blade and the angular velocity of the gear blank are such that the gear blank increments a number of cut positions after each cut which number is greater than one and prime to the total number of gears to be cut. The accessory includes a pivotal and oscillating gear blank carriage. A blank on the carriage is rotated through change gears by a main timing shaft. The timing shaft also controls vertical movement of the cutting blade through a cam, a rack and pinion assembly and change gears. Further, through another cam the timing shaft controls retraction of the gear blank from the cutter blade. Proper selection of change gears enables cutting of gears of any pitch or diameter.

Abstract: A method for manufacturing precision gate-rotors and gate-rotor supports a single-screw mechanism by cutting the complex tooth profiles in a cylindrical gate-rotor blank. The cylindrical blank is rotated about its center axis as a cutting tool is translated in a fixed two-axis plane, one axis being the centerline of the cylindrical blank and the second axis being a line extending radially therefrom. This process may be carried out by a multi-axis, numerically controlled milling machine.

Abstract: This invention pertains to a rack and pinion type steering gear for an automobile and a method for cutting rack teeth in the gear. The gear comprises a housing, a pinion rotatably supported within the housing and operatively connected to a steering wheel and a rack bar supported within the housing for slidable movement in the axial direction and rotation and provided with rack teeth in engagement with the pinion. The rack teeth are formed on the rack and along a varying pitch line so that the axial movement amount of the rack varies as the pinion rotates.

Abstract: A rotary indexing table having a generally circular top plate rotatably secured to a fixed base structure is disclosed. An outer race annular ring is connected to the top of the fixed base structure and extends radially over a central bore formed in the top face of the fixed based structure. A first ring of teeth is formed on the circular top plate. A second ring of teeth is formed on the outer race annular ring. Both the first and second rings of teeth face toward the central bore in the fixed base structure. A piston is slidably mounted in the central bore. The piston has a third ring of teeth aligned with the first ring of teeth and a fourth ring of teeth aligned with the second ring of teeth. A method of forming the third and fourth rings of teeth on the piston is also disclosed. The method includes mounting a sine block on a work table. Then fastening a rotary indexing table on the top of the sine block. Next, securing the piston to the top of the rotary indexing table.
