Precautions when using Wiper inserts About wiper inserts A wiper insert is designed with a wiper edge that is located between corner radius and straight Finishing cutting edge cutting edge shown as right figure. (Wiper edge) Advantages · A wiper edge geometry provides improved surface finish quality even at increased feed rate Corner-R · Improved machining efficiency : Reduced cutting time with higher feed rate as well as Straight cutting edge consolidation of roughing and finishing provide high machining efficiency · Longer tool life : Reduced cutting time with higher feed rate leads to increase part production · Excellent chip control : Higher feed rate makes chips thicker, which provides easier-to-break chips Precautions when using WF / WE Chipbreaker (Negative Insert) Tip of corner-R (DNMX, TNMX) Wiper insert edge line Standard insert corner-R Edge line after offset Biting amount Z-axis direction cutting edge offsets at radius part X-axis (+) Z-axis (+) cutting edge effsets X-axis direction Standard insert corner edge line Cautions when machining inside corner-R R Do not use this wiper insert if a precise inside corner-R is required when such a machining in the figure below.
