Abstract: A power source for electric discharge machining employing a capacitor discharge circuit with charging and discharging switching elements Q1, Q2 for use in an electric discharge machining apparatus, wherein no resistance for limiting charging current is used in order to eliminate energy loss and to prevent the switching element Q1 from breaking due to surge voltage of the switching element Q1. Further, a diode D is provided in parallel with the discharging capacitor C1. The diode D, the charging switching element Q1, and a capacitor C2 for smoothing the power source are fabricated in the form of a printed circuit board in order to reduce the stray inductance and to limit surge voltage.

Abstract: The invention concerns a method and device for simultaneously working different parts of the surface of one and the same workpiece using two abrasive wheels. The method calls first for the smooth-polishing positions of the two abrasive wheels (4.1; 4.2) to be calculated. When the two abrasive wheels (4.1; 4.2) have been brought into these positions, the abrasive wheels (4.1; 4.2) are shaped with a dressing tool (1), thus producing the surface roughness appropriate for rough-grinding. Subsequently, the abrasive wheels (4.1; 4.2) are brought into the calculated rough-grinding positions and the rough-grinding carried out. The abrasive wheels (4.1; 4.2) are then brought into the smooth-polishing positions. In the following dressing procedure, the surface roughness appropriate for smooth-polishing is produced. The smooth-polishing is then carried out. In the device proposed, the abrasive-wheel carriages (14.1; 14.2) are disposed such that the two abrasive wheels (4.1; 4.2) have a common axis of rotation (15). A rotating dressing tool (1) mounted on a device (16) which can move in two dimensions is disposed parallel to this axis (15). The dressing tool (1) can be used to shape all the parts of the abrasive-wheel surface. The surface thus produced is reproduced accurately on the workpiece (2).

Abstract: Disclosed herein is a process and apparatus for grinding tooth surfaces of spur and helical gears by a generating method. The outer tooth surfaces (4) of a theoretical ring gear (6) are conjugate to the grinding surfaces (3) along the width of a generally hourglass shaped grinding wheel (2). The grinding wheel (2) is rotated which in turn causes the theoretical ring gear (6) to rotate. A work gear (8) is rotated in mesh with the internal tooth surfaces (10) of the theoretical ring gear (6) and simultaneously is traversed in mesh across the width of the grinding wheel (2) with the center of the work gear (Xw) moving in a path (12) about the center of the theoretical ring gear (XI).

Abstract: A method for producing the rack of variable ratio rack-and-pinion steering arrangements in which a uniformly toothed pinion meshes with a non-uniformly toothed rack. The rack has a central section (7) of uniform pitch and tooth shape flanked by two outer sections (8) having a different pitch and tooth shape so as to vary the steering ratio in dependence upon the position of the rack, the teeth in the transitional areas between the central section and the outer sections being of modified shape and pitch. The method comprises the steps of forming a rack with a central section (7) of uniform pitch and tooth shape, forming two outer sections (8) disposed one at a preset distance from each end of the central section (7) and having uniform pitch and tooth shape differing from the pitch and tooth shape of the central section, and producing transitional areas by form-grinding transitional tooth spaces (9, 10 and 9', 10') between the respective sections (7 and 8), which tooth spaces fan out from central points defined by the points of intersection (F and F1) of the helix angles of the last tooth spaces (A and A1 respectively) of the central section and the first tooth spaces (D and D1) of the respective outer sections (7 and 8).
