2 Technical Information - Special features External thread A thread on the external surface of a cylinder screw or cone epth of thread The distance between the crest and root measured from normal to the axis The distance between the corresponding points on adjacent thread forms measured parallel to the axis. This distance can be defined in millimeters or by the tpi (threads per inch), which is the reciprocal of the pitch Root Crest External thread Major Ø Ø Minor Ø Thread angle Helix angle Major diameter The largest diameter of a screw thread diameter On a straight thread, the diameter of an imaginary cylinder, the surface of which cuts the thread forms where the width of the thread and groove are equal Minor diameter The smallest diameter of a screw thread Helix angle For a straight thread, where the lead of the thread and the pitch diameter circle circumference form a right angled triangle, the helix angle is the angle opposite of the lead Nominal diameter The diameter of which the diameter limits are derived by the application of deviation allowances and tolerances Internal thread A thread on the internal surface of a cylinder or cone Straight thread A thread formed on a cylinder Taper thread A thread formed on a cone Left handed thread Right handed thread The helix angle (ß) Helix angle (ß) A thread which, when viewed axially, winds in a counter clockwise and receding direction. All left handed threads are designated LH A thread which, when viewed axially, winds in a clockwise and receding direction. Threads are always right handed unless they are specified Lead (L) For a straight thread, where the lead of the thread and the pitch diameter circle circumference form a right angled triangle, the helix angle is the angle opposite of the lead Machining a multi-start thread A thread in which the lead is an integral multiple, greater than one, of the pitch. A multi-start thread permits a more rapid advance without a coarser (larger) thread form First start machined Second start machined Third start machined (final, 3 starts thread) Lead Lead Insert profile style Partial profile Full profile Full profile for fine pitches Semi full The V partial profile insert cuts without topping the outer diameter of the thread. The same insert can be used for a range of different thread pitches which have a common thread angle The full profile insert will form a complete thread profile including the crest. For every thread pitch and standard, a separate insert is required The full profile for Fine es will form a complete thread. The topping of the outer diameter is generated by second tooth The Semi profile insert will form a complete thread including crest radius but without topping the outer diameter. Mainly used for trapezoidal profiles 3

4 Technical Information - Thread infeed method Radial infeed Flank infeed (modified) Alternate flank infeed Radial infeed is the simplest and quickest method. The feed is perpendicular to the turning axis, and both flanks of the insert perform the cutting operation. Radial infeed is recommended in 3 cases: When the pitch is smaller than 16 tpi (1.5mm) For material with short chips For work with hardened material Flank infeed is recommended in the following cases: When the thread pitch is greater than 16 tpi (1.5mm). Using the radial method, the effective cutting edge length is too large, resulting in chatter. for TRAPEZ and ACME. The radial method result in three cutting edges, making chip flow very difficult Use of the alternate flank method is recommended especially in large pitches and for materials with long chips: This method divides the load equally on both flanks, resulting in equal wear along the cutting edges. Alternate flank infeed requires more complicated programming, and is not available on all lathes Shim Shape of shim ATE ATI Insert size Helix angle d L ATE16-3P ATI16-3P ATE22-3P ATI22-3P ATE16-2P ATI16-2P ATE22-2P ATI22-2P ATE16-1P ATI16-1P ATE22-1P ATI22-1P ATE16 ATI16 ATE22 ATI22 ATE16-1N ATI16-1N ATE22-1N ATI22-1N ATE16-1.5N ATI16-1.5N ATE22-1.5N ATI22-1.5N ATE16-2N ATI16-2N ATE22-2N ATI22-2N ATE16-3N ATI16-3N ATE22-3N ATI22-3N Holder ERH-16 / ILH-16 IRH-16 / ELH-16 ERH-22 / ILH-22 IRH-22 / ELH ATE27-3P ATI27-3P ATE27-2P ATI27-2P ATE27-1P ATI27-1P ATE27 ATI27 ATE27-1N ATI27-1N ATE27-1.5N ATI27-1.5N ATE27-2N ATI27-2N ATE27-3N ATI27-3N ERH-27 / ILH-27 IRH-27 / ELH-27 Standard shim has lead angle 1.5 Application grade Grade Features Available insert type PC5300 PV 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 TiAlN coating - Outstanding performance on high speed machining General Grade - A tough sub-micron substrate with TiAlN coating provides good fracture toughness and excellent wear resistance - Outstanding performance on stainless steels and hard-to-cut materials ERM/IRM (Insert with chip breaker) ER/IR (Ground insert) Recommended cutting speed ISO Workpiece Grade P Carbon steel, alloy steel, cast steel PC5300 M Stainless steel, heat resistant steel, titanium alloy steel PC5300 K Carbon iron, aluminium, cast steel, copper PC5300 5
