Face grooving GDFM/GDFMS type KGDF: Face grooving 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 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 Insert Top and bottom profiles from slip of insert. of the part gripped 2. Improves repetitive installation accuracy of insert (GDFM and GDFMS G inserts are not applicable to KGD external grooving, cut-off and KGDI Toolholder internal grooving toolholders.) W grip technology Smooth chip control Grooving For general purpose GM chipbreaker, for high feed grooving GH chipbreaker, for deep grooving DM chipbreaker Advantages of chipbreaker GM: General purpose GH: High feed grooving DM: Deep grooving Smooth surface from cutting edge Gradually raised surface: to the far side: Keeps curling of chips in Concave part in middle: Concave part in middle: Enhances breaking of chips and constant shape. Control chips upward. Enhances breaking of chips. maintains their evacuation Inflated inner surface: direction constant. Dots jutted out center side: Changes chip shape smoothly. Enhances breaking of chips Stable chip control during and maintains their evacuation shoulder grooving. direction constant. Slope portion: Constantly curled chips. Flat cutting edge line: Improves chip control. Negative cutting edge line: Smooth surface up to the far Improvement of strong edge. side standing wall: Reduces cutting force, enhances Steep surface near the cutting edge: breaking of chips and maintains Good chip control during shoulder grooving. their evacuation in constant direction. Curved lead edge: Keeps chips in constant shape.
