KINEFAC ULTRA HIGH SPEED PARTS  FORMING

Thrufeed and cutoff  roll forming is  an ultrahigh speed rotary open-die forging process. It is similar to skewed-axis thread rolling process, but differs in that instead of producing continuous helix thread form, it produces simple discrete forms such as balls, rings, rollers and pins with conical ends. A typical application is the rolling of 1/8" (3.2 mm) low-carbon steel balls at rates exceeding 4000 per minute. Other applications include  military munitions rotating band with an O.D. 1-1/2 (38.1 mm) and wall thickness of 1/8 (3.2 mm) at 200 parts per minute. Such production rates, combined with material savings, excellent form repeatability, and in some cases superior physical characteristics make the process worthy of consideration by anyone faced with the problem of producing high volumes of small parts with simple shapes
