CBN & PCD TURNING INSERTS CBN & PCD TURNING INSERTS WIPER INSERT Mmproving Surface Finish Under the same machining conditions as conventional breakers but with the feed rate increased the surface finish of the workpiece can be improved. Mmproving Efficiency High feed rates not only shorten machining times but also make it possible to combine roughing and finishing operations. Mncreased Tool Life When a change to high feed conditions the time required to cut one component is decreased thus more parts can be machined with each insert. In addition the high feed rate prevents rubbing therefore delaying the progression of wear and increasing the tool life of the insert. Mmproving Chip Control Under high feed conditions the chips generated become thicker and are more easily broken thus chip control is improved. Insert example Wiper insert for low rigidity workpieces NP-CNGA120408GAWS2 New wiper edge code- CUTTING PERFORMANCE Cutting Conditions Workpiece Hardened Material (HRC60) Depth of Cut :0.1mm Insert NP-CNGA120408GAWS2 Dry Cutting Cutting Speed 120m/min E a t a 10 Feed (mm/rev) NOTES FOR USE No Restriction for Holders A standard holders can be used. ( A double clamp high rigidity tool is recommended.) Restriction for Holders Use a holder with end cutting angle 93 for improving wiper efficiency. A holder with end cutting angle 91 can improve wiper efficiency however there is no wiper efficiency with other end cutting angles (60 90107etc.).
