When the cutting width, depth or overhang length is large, welding occurs on cutting edges. (ex. aluminium machining). set Vc and fz to the lower recommended values and check the machine power · For the operation with depth of cut which varies (ex. casting skin) and machining and vibration. Others of workpiece materials with interrupted surface, the feed (fz) should be set to the lower recommened value shown in the above table. Installation of inserts on an extra close-pitch cutter • On an extra close-pitch cutter, the screw hole of an insert pocket is placed at an angle. • Leave a gap between the insert and pocket when starting to fasten the screw on the cutter body as shown in Fig. A. • After fastening the screw, please ensure that there is no gap Leave a gap between the cutter body and insert. (Fig. B) when starting to fasten the screw. Fig. A Fig. B Notes for using wiper inserts Notch • When fine surface finish is required, wiper insert PNCU0905GNER-W is recommended. • Attach the insert with its notch on the top, as shown in Fig. C. Cutting • Also, make sure that the mark of the insert is located at the bottom edge of the cutter body, as shown in Fig. D. • The wiper insert has two corners available (Fig. D). Do not use the other corners as the cutter body may be broken. Cutting edge Mark Fig. C Fig. D H072 www.tungaloy.com
