Title: METHOD AND DEVICE FOR PRODUCING TOOTHED RACKS
Abstract:
The invention relates to a method for producing toothed racks (51, 61) which extend in the direction of a longitudinal axis (L) and comprise, in a toothing plane parallel to the longitudinal axis (L), a toothing (9) having teeth (92) extending in a tooth direction transverse to the longitudinal axis (L), in which method at least one rack blank (5, 6) is clamped in a clamping device (3) and a tool head (2) of a machining tool is moved in the tooth direction with the tool engaging parallel to the toothing plane such that the tool head (2) introduces at least one tooth parallel to the toothing plane. To enable more effective production of toothed racks and faster creation of the toothing (9), according to the invention, at least two rack blanks (5, 6) are clamped in parallel next to each other in the clamping device (3), and the tool head is moved in one continuous working stroke over both rack blanks (5, 6) with the tool being in continuous engagement parallel to the common toothing plane (7).
