Guide for External Machining Guide for External Machining PointLongitudinal turning after GroovingGrooving Depth Over 0.5mm: For roughing (Refer to Fig. 1)Before longitudinal turning, pull the tool back about 0.1mm after grooving,instead of longitudinal turning subsequent to grooving.(Failure to pull the tool back before traverse cutting will result in an unbalancedload applied on only one side of the cutting edge.)Before Longitudinal turning, pull thetool back about 0.1mm after grooving,instead of Longitudinal turningsubsequent to grooving.GroovingDepth Over 0.5mm: At roughingFig.1Grooving Depth under 0.5mm: For finishing (Refer to Fig. 2)Longitudinal turning subsequent to grooving is possible because shallow groovedepths relate a small load on the cutting edge.(Dwell-motion is not necessary.)G PointWhen widening the groove width (Refer to Fig. 3)Apply the “Step Turning”.Then perform finishing.(For better chip control, over 0.5 mm ap isrecommended.)NoteIf machining is made toward the center but the center isnot pressed, lower the feed rate.Traversing subsequent to groovingGrooving Depth under 0.5mm: AtfinishingFig.2GroovingFig.3 Case Studies17Cr3 SCr420HGrooving20CrMo5 SCM420 TraversingGroovingGearVc=113164 m/minf=0.06 mm/revWetGDM4020N-040GM(PR1225)KGDL2525X-3T10S10 ø24ø35GearVc=170m/minf=0.15 mm/revRoughing0.10 mm/revFinishingap=0.2mmFinishingWetGDM4020N-040GM(PR1215)KGDR2525X-4T20Sø73ø38ø54GM ChipbreakerPR1225Competitor KPVD Coated Carbide250 pcs/C1500 pcs/Cx6 longer lifeGM ChipbreakerPR1215Competitor L(Raughing: PVD Coated Carbide)(Finishing: Cermet)250 pcs/C200 pcs/CResultKGD type grooving toolholder + GM chipbreaker (PR1225) showed6 times longer tool life than that of Competitor K.Good chip control without burned chips.ResultGM chipbreaker reduced occurrence rate of tangle of chips (occurrencerate 80% => 10%).

Face Grooving Dia. øDFace grooving diameter (øD) is the suitable value for the initialgrooving on the unprocessed workpiece (see Fig.1). Then,you can widen it up to the center towards the inside (excludingthe models listed in the right table), and towards the outsideaccording to machine limits. Minimum traversing diameter of small grooveTraversing towards the Center causes the toolholder to interfere with the groove wall depending on the initial cut's diameter.øD2825 26 27OverødDescriptionødKGDF 2020X25-3AS4 2 0 02525X25-3ASøDKGDF 2020X25-4AS6 3 02525X25-4ASInterferenceKGDF 2020X25-5AS7 4 1Remaining Boss Dia.ød2525X25-5ASKGDF 2020X25-6AS9 4 12525X25-6ASExample)If a groove of external diameter ø25 is created usingKGDFR2020X25-3AS and traversing is made toward the inside, aø4 portion will be left in middle due to interference of toolholder.(No remaining Boss)Fig.1G72: Std.

For Successful Machining with KGDF Points to be checked for face grooving1Toolholder SelectionCheck the range of applicable“face grooving diameter” aswell as the groove width anddepth.Machining conditions(Feed rate: f)When machining onsteel, set the feed rate (f)so that chips are createdin a helical form in cut-off(see Fig. 1).How to widen the groove (Cut-off and Longitudinal turning)Start machining from the outside and then proceed to the inside.Chip control will be better in this way.Cut-off (Grooving + Side grooving)Longitudinal turningGGroovingGuide for longitudinal turning. When the cutting amount (ap)is over 0.5 mmPerform Cut-off.Return the cutting by 0.1 mm.Perform longitudinal turning.(See Fig.1)Fig.1When widening the face groove widthSee Fig.2Apply the “Step Turning”.Then perform finishing.Fig.2B. When the cutting amount (ap) isunder 0.5 mmPerform Cut-off.Perform longitudinal turning.Machining without interruption ispossible. (See Fig.3)Fig.3G75

Grooving Depth under 0.5mm: At finishing (Refer to Fig.2)Longitudinal turning subsequent to grooving is possible because shallowgroove depths relate a small load on the cutting edge.(Retention time is not necessary.)Before Longitudinal turning, pull the toolback about 0.1mm after grooving(Grooving Depth Over 0.5mm: At roughing)Fig.1 Point ( )When widening the groove width, apply the “Step Turning”Gas shown in Fig.3.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 centerLogitudinal turning subsequent togrooving is possible because there is onlya small force on the cutting edge.Fig.2GroovingFig.3 Guide for Face GroovingToolholder Selection Choose the best tool depending on the groove width.The machining Dia. øD listed in the catalog indicates the depthof the first plunge of face grooving as shown in Fig.1.

Increase the cutting speed for finishing process only. (This can handle most of the cases).If the method is not successful, try as follows.Countermeasures Check the insert edge's parallelness.Adjustment: Apply the insert edge tothe work face and adjust the toolholderwithin the angle of ±5'. (Fig.7)905Fig.7Chips are entangled.Install the toolholder in the reverse position.Adjust the coolant flow to the cutting edge. When widening the groove, do not machine one deep groove.Instead, repeat shallow grooving and turning.Insert cracks whenLongitudinal turning.Reverse the facing direction.Groove is not straight.Check the edge's parallelness.Decrease the feed rate.G95
