SEC-Threading Tools SSTE Type / SSTI Type ■ Shim Selection f the pitch is large or the thread diameter is small, the thread lead angle will beome large and the effective clearance angle will become small. A A It is ideal to set the threading insert so the left and right clearance angles are equal. Shim In order to do this, it is necessary to choose the correct shim based on the Insert Insert machining thread pitch and effective diameter using the table below. ß° 1 ≒ Lead angle Shim (ideal condition) ß° 2: Shim angle Lead angle A-A cross-section ■ Shim Selection Procedure ① Chose either right thread or left thread based on the table below. For external: YE3-3P For external: YE3-2P For external: YE3-1P ② Confirm the machining thread pitch row. T1 4.5° For internal: YI3-3P T1 3.5° For internal: YI3-2P T1 2.5° For internal: YI3-1P ① Confirm the value that matches the machining thread effective diameter. ② Confirm the part number of shim listed above for the corresponding value. If Nonmachinable areas D D D it is different from the part number you are currently using, change the shim. For external: YE3 3.0 T1 1.5° For internal: YI3 * Standard shim attached to holders Pitch (mm) 2.0 Example: If you re machining a right M16 × 2.0 thread, the effective diameter is 14.701 mm, so the 1.0 T1 0.5° For external: YE3-1N values of a [2.0] mm pitch and [11.4 to 17.4] mm For internal: YI3-1N F effective diameter in the table correspond. Therefore the YE3-1p in the For External 0 10 20 30 40 50 60 70 Threading Diameter column is the corresponding shim.
