KGDF Face Grooving  Features  Separate type toolholder (toolholder + blade) and Integral type toolholder are available. Adaptable to a wide range of face grooving applications by changing blades Separate type toolholder  New insert clamping system "W Grip" Toolholder Unique "W Grip" (insert anti-slip structure) provides stable machining quality 1) Prevents abnormal machining surface and / or insert breakage resulting from slip Top and bottom profiles of insert. Insert of the part gripped 2) Improves repetitive installation accuracy of insert GDFM and GDFMS inserts are not applicable to KGD external grooving, Toolholder cut-off and KGDI internal grooving toolholders. G  Smooth chip control W Grip technology For general purpose GM Chipbreaker, For high feed grooving GH Chipbreaker, For deep grooving DM Chipbreaker  Advantages of Chipbreaker Grooving For general purpose GM Chipbreaker For high feed grooving GH Chipbreaker For deep grooving DM Chipbreaker · Smooth surface from cutting · Gradually raised surface. · Concave part in middle · Concave part in middle edge to the far side Keeps curling of chips in · Dots jutted out center side Control chips upward. Enhances breaking of chips. Enhances breaking of chips constant shape. Changes chip shape smoothly. · Inflated inner surface External and maintains their evacuation Stable chip control during Enhances breaking of chips direction constant. shoulder grooving. and maintains their evacuation direction constant. Internal · Slope portion Face Constantly curled chips. · Flat cutting edge line Improves chip control. · Negative cutting edge line · Smooth surface up to the Improvement of strong edge. far side standing wall · Steep surface near the cutting edge Reduces cutting force, enhances breaking of chips and Good chip control during shoulder grooving. maintains their evacuation in constant direction. · Curved lead edge Keeps chips in constant shape.  Chip Control of GM Chipbreaker Vc=150m/min f=0.05~0.2mm/rev GDFM5020N-040GM SCM415 Wet  Face Grooving (φ62)  Side Grooving  Turning (mm) 0.8 Width ae 1.0 ap (mm) 0.5 0.05 0.08 0.1 Cutting 0.5 Feed Rate f (mm/rev) 0.2 0.1 0.15 0.2 0.05 0.1 0.15 Feed Rate f (mm/rev) Feed Rate f (mm/rev)  High precision edge preparation High precision molding technology with tolerance ±0.03mm (Edge width 2, 3, 4mm types)  Highly-reputed MEGACOAT technology Long tool life and high efficiency machining achieved by superior oxidation resistance and wear resistance.
