Technical information X-axis direction setscutting edge e 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 cutting edge shown as right figure. Finishing cutting edge(Wiper edge) Advantages · A wiper edge geometry provides improved surface finish quality even at increased feed rate · Improved machining efficiency : Reduced cutting time with higher feed rate as well as Corner-R 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 o set Biting amount Z-axis direction cutting edge o sets at radius part X-axis (+) Z-axis (+) 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. DNMX / TNMX WF Chipbreaker Unmachined part · More incomplete cutting and excessive cutting Cut-away during machining with this chipbreaker than Standard insert corner-R the machining with a standard insert Wiper insert corner-R · The inside corner-R dimension become smaller than the requirement. CNMG / WNMGWF / WE Chipbreaker* From external turning to up facing without arc complement(A wiper edge does not work during up facing)·The inside corner-R dimension would be smallerthan the requirement (Cutting excessively).Standard insert corner-R Cut-away Wiper insert corner-R R32
