Changing the corner Shape of Knurling

Updated: Jun 1

Machining products such as Shafts, Pins or Rollers where Knurling is done on “Chamfered” corner, it is likely to have burr on the corner which gives us extra job to deal with burrs that increase production costs.




Rather than “Chamfering”, “Radial” corner are preferable in terms of burr prevention.




We, E&H Precision has over 10 rolling / knurling machines from NISSEI Co., Ltd. and PROFIROLL TECHNOLOGIES GMBH.
