Technical Information for Threading O Thread infeed method Infeed Application Radial infeed When the pitch is smaller than 16 tpi R f infeed is thesimPlest and quickest method n . i -.u u u- The feed is perpendicular to the turning axis, and both F°r mat rial with short chips flanks oftheinsPert perform the cutting, operation For work with hardened material Radial infeed is recommended in 3 cases 1-3 Flank infeed (modified) When the thread pitch is greater than 16 tpi. Using the radial method,the effective cutting edge length is too large, resulting in chatter. for TRAPEZ Flank infeed is recommended in the following cases and ACME. The radial method results in three cutting edges, making chip flow very difficult Alternate flank infeed This method divides me load equaHy °n MM flanks, use of the alternate flank method is recommended resulting in equal wear along the cutting edges especially in large pitches and for materials with Alternate flank infeed requires more complicated lf' ' 3 r programming, and is not available on all lathes long chips Shim .C 0 IE (0 c c B m ATE (External) ATI (Through) Insert d 9.525 12.7 15.875 size L 16 22 27 Holder ER(L)H IR(L)H ER(L)H IR(L)H ER(L)H IR(L)H Ordering code ATE16 ATI16 ATE22 ATI22 ATE27 ATI27 Standard shim has lead angle 1.5° O Application grade Grade Features Available insert type PC5300 Universal grade For chip breaker type only Stable machining on a wide application due to fine-grained carbide substrate with balanced heat resistance and toughness Excellent wear resistance and oxidation resistance due to AiTN coating film Outstanding performance on high speed machining ERM/IRM (Insert with Chip breaker) PC3030T Specialized grade for threading inserts A tough sub-micron substrate with TiAlN coating provides good fracture toughness and excellent wear resistance Outstanding performance on STS and hard to cut materials ER/IR (Ground insert) PC9070 Specialized grade for threading inserts Strong wear resistance in stainless machining thanks to multilayer PVD coatings E/IR (Ground insert) 0 Recommended cutting speed as per workpiece (vc) Workpiece .> P Carbon steel, Alloy steel, Cast Steel PC5300 PC3030T M Stainless steel, Heat resistant steel, Titanium alloy steel PC5300 PC3030T PC9070 K Carbon Iron, Aluminum, Cast Steel, Copper PC5300 PC3030T Threading 5
