FIELD: machine engineering, namely manufacture of flat threading dies for threading by plastic deforming process.
SUBSTANCE: apparatus includes housing with two mutually normal linear guides placed in horizontal plane; slide performing main reciprocation lengthwise motion along one guide of housing; carriage performing cross feed motion along other guide of housing; carriage placed in guides of slide arranged along the same axis as guides of carriage at neutral position of slide. In order to enhance efficiency, apparatus is provided with cylindrical knurling tool having threading knurl. Apparatus may have contour follower mounted on housing and providing possibility for simultaneously working two or more threading dies. At least one threading die has several flat portions inclined one relative to other. Carriage is provided with roller that rolls on surface of contour follower. In order to provide constant engagement of roller and contour follower, carriage may be spring-loaded relative to follower.
EFFECT: enhanced efficiency of apparatus.
