STANDARD KNURLING WHEEL

Knurling profile at the knurling wheel

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.

SACutting wheel with sharp edges and axially parallel toothing, plunge and feed knurling possible. Creates positive knurl at the workpiece.
SRCutting wheel with sharp edges and teething with right-hand twist. Plunge and feed knurling possible.
Creates positive knurl at the workpiece.
SLCutting wheel with sharp edges and teething with left-hand twist. Plunge and feed knurling possible. Creates positive knurl at the workpiece.
BORolling wheel with teethed radius and axially parallel teething. Plunge and feed knurling possible. Creates positive knurl at the workpiece.
EBOCorner- rolling knurling wheel with teethed radius and axially parallel teething. Plunge and feed knurling possible. Creates positive knurl at the workpiece.
EACorner-rolling knurling wheel with bilateral chamfer and axially parallel toothing. Plunge and feed knurling possible. Creates positive knurl at the workpiece.
AARolling wheel with bilateral chamfer and axially parallel teething. Plunge and feed knurling possible. Creates positive knurl at the workpiece.
BRRolling wheel with bilateral chamfer and teething with right-hand twist. Plunge and feed knurling possible. Creates positive knurl at the workpiece.
BLRolling wheel with bilateral chamfer and teething with left-hand twist. Plunge and feed knurling possible. Creates positive knurl at the workpiece.
GELeft-hand, right-hand knurling wheel, points raised, left-hand and right-hand twist. Only applicable in plunge procedure. Creates a negative knurl at the workpiece.
KECross-knurl wheel, points raised, axial and radial grooves. Only applicable in plunge procedure. Creates a negative knurl at the workpiece.

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.
