Abstract
In order to minimize the sliding friction occurring between the locking parts, that is, between the pawl and the rotary latch of a motor vehicle lock, it is advantageous if, during the machining process, the different latch surfaces of both locking parts are provided with a punched contour and with a contour having a oblique machining groove. Machining grooves are formed, in particular on the latch surface thereof, after stamping the pawl. Defined shapes of oblique channels and/or machining grooves are produced, for example, by milling out the machining grooves. The oblique machining grooves are produced at a defined angle and guarantee that the straight channels on the rotary latch only have a few overlapping points with the oblique grooves, if both locking parts come into contact with each other.
