GROOVING GUIDE FOR GROOVING GVF INSERT Guide for External Grooving > Point (I) (Turning after Grooving) 1) Grooving Depth Over 0.5mm: At roughing (Refer to Fig.1) Before turning, pull the tool back about 0.1mm after grooving, instead of turning subsequent to grooving. (Failure to pull the tool back before traverse machining will result in an unbalanced load applied on only one side of the cutting edge.) 2) Grooving Depth under 0.5mm: At finishing (Refer to Fig.2) Turning subsequent to grooving is possible because shallow groove depths relate a small load on the cutting edge. (Retention time is not necessary.) > Point (II) 1) When widening the groove width (Refer to Fig.3), apply the “Step Turning” as shown in Fig.3. 2) The widened groove and side walls should be finished last. (For better chip control, ap over 0.5mm is recommended.) Note) If the workpiece is not supported at the center, reduce the feed rate when grooving towards center. Before turning, pull the tool back about 0.1mm after grooving. (Grooving Depth Over 0.5mm: At roughing) Fig.1 Turning subsequent to grooving is possible because there is only a small force on the cutting edge. (Grooving Depth under 0.5mm: At finishing) Fig.2 Guide for Face Grooving (1) Choose the best tool depending on the groove width. The Cutting Dia. 0D listed in the catalog indicates the depth of the first plunge of face grooving as shown in Fig.1. (2) Confirm Grooving Depth (dimension T) Fig.1 (3) It is recommended to install the toolholder in the reverse position. (Fig. 2) (This will provide smooth chip flow and chip clearance.) Turning direction should be from the outer diameter to the inner diameter as shown in Fig.3 This improves chip evacuation. Fig.3 T G130 Kyocera
