... the proven solution for high productivity!• New improved PVD TiAlN-coated grades aredesigned to cut a variety of workpiece materials.• New CVD KENNA PERFECT and KENNA UNIVERSALgrades.• Rigid clamping securely locks insert in placethrough the toughest cuts.• Versatile design enables one system to handleO.D. and I.D. grooving, face grooving, backturning, undercutting, and even threadingoperations.• Chip control inserts provide excellent chipevacuation in grooving, and offer better controlin multi-directional turning.123Our rigid clamping design prevents insertmovement during high-feed rate applications.This benefit ensures excellent surface finish,improved productivity, and superior tool life, andpromotes perfect concentricity. The rugged bridgeclamp generates locking forces in three directionsto provide superior resistance to side thrust andtangential forces.B7

TOP NOTCH Grooving – Technical DataMachining GuidelinesA2 A3 A4 TOP NOTCHGROOVING & CUT-OFF TOOLSMachining Guidelines for Chip Control –Grooving• Center height of insert should be positioned at thecenter of the workpiece, or up to .005 inch (0,13 mm) above.• Dwell time in the bottom of the groove, more than three revolutions,is not recommended.• Chip control is feed rate related, and should be adjusted to fit theparticular situation. Recommended feed range is .003-0.012 ipr(0,08-0,3 mm/rev).Groove Limits (Maximum Internal Groove DepthVersus Minimum Bore Diameter)insertMachining Guidelines for Chip Control –Turning/Profiling• Maximum depth of cut for side cutting (turning/profiling) dependsupon material being cut and width of the tool. However, some generalguidelines are:1) .031 - .062 inch (0,79-1,6 mm) wide insert can cut up to .025 inch(0,6 mm) deep.2) .067 - .128 inch (1,7-3,3 mm) wide insert can cut up to .040 inch(1,0 mm) deep.3) .138 - .189 inch (3,5-4,8 mm) wide insert can cut up to .080 inch(2,0 mm) deep.4) .197-.375 inch (5,0-9,5 mm) wide insert can cut up to .120 inch(3,0 mm) deep.Finish turning the groove1. Plunge both sides of groove width.2. Plunge center area to remove webof material remaining.3. To avoid insert chipping and toachieve groove wallperpendicularity, follow the toolpath outlined here.4. Use the lightest depth of cut thatstill allows good chip breaking, toollife, and surface finish.maximumgroove depthminimumbore diameterinsertmaximumgroove depthminimumbore diameterinch mm inch mm inch mm inch mmNG-1094L .075 1,91 .800 20,32.040 1,02 .440 11,18NG-2031R/L .050 1,27 .730 18,54NG-2041R/LNG-2047R/LNG-2058R/L.110 2,79 2.500 63,5NG-2062R/L .102 2,59 1.750 44,45NG-2094R/L .098 2,49 1.500 38,10NG-2125R/L .080 2,03 1.000 25,40.055 1,40 .730 18,54NG-3047R/LNG-3062R/L .094 2,39 1.750 44,45NG-3072R/L .090 2,29 1.625 41,28NG-3078R/L .075 1,91 1.375 34,93NG-3088R/LNG-3094R/LNG-3097R/L .150 3,81 2.375 60,33NG-3105R/LNG-3110R/L .145 3,68 2.125 53,98NG-3122R/LNG-3125R/L .138 3,51 1.875 47,63NG-3142R/LNG-3156R/L .125 3,18 1.625 41,28NG-3178R/LNG-3185R/L .110 2,79 1.375 34,93NG-3189R/L.375 9,53 28.812 731,82NG-5250R/L .361 9,17 15.812 401,62NG-5281R/L .344 8,74 10.812 274,62NG-5312R/L .327 8,31 7.312 185,72NG-5344R/L .294 7,47 4.812 122,22NG-5375R/L .257 6,53 3.562 90,47.215 5,46 2.812 71,42NG-6250R/L .250 6,35 5.750 146,05NG-6281R/L .245 6,22 5.000 127,00NG-6312R/L .240 6,10 4.500 114,30NG-6344R/L .218 5,54 3.250 82,55NG-6375R/L .200 5,08 2.500 63,50Internal Groove Depth Versus Bar Interferenceminimum borediameter at maximumgroove depthminimumgroove depthNG-4125R/L .150 3,81 2.750 69,85.250 6,35 5.750 146,05NG-4189R/L .245 6,22 5.000 127,00NG-4213R/L .240 6,10 4.500 114,30NG-4219R/L .218 5,54 3.250 82,55NG-4250R/L .200 5,08 2.500 63,50NOTE: Internal grooving depth limits are a function of bar clearanceversus bore diameters.*The same maximum groove depth and minimum bore diameter values also apply to metric, NG-K (chip control), and NR (full radius) inserts of similar size.B34
