DIN 403 describes and specifies the knurl profile at the knurling wheel with knurl profiles AA, BL, BR, GE, GV, KE and KV. Since the DIN does not provide any comprehensive specification, Böni knurling wheels are produced similar to DIN 403. We have extended the knurling wheels by further knurling wheel designations. Special knurling wheels of Böni AG are customized according to customer drawing.
The following knurling wheels are not required using Böni tangential knurling tools. For these knurling-wheel types GV and KV the points are incorporated in the knurling wheel. Applying these knurling wheels involves enormous lateral forces which are not accepted by a counter roller or a second knurling wheel. The workpiece material may move away and an inferior knurl may develop. The same knurling profile RGE or RKE is achieved using a tangential knurling tool and standard knurling wheels.
Therefore, these knurling wheels should only be used in case of extreme emergency.
Prerequisite for applying these knurling wheels: The material must be capable of being cold-formed.
