ISO 5686:2024 Polygonal turret interface with flat contact surface – Part 1: Shanks of type F, H and A
CDN $336.00
Description
This document specifies the dimensions of polygonal taper shanks with flat contact surface (PTI). These shanks are the tool-side part of the interface to the (in cutting process non-rotating) tool carrier of machine tools (e.g. turret lathes, turning centres).
This document specifies three types of tool-side interface types, which differ at the face contact. The tool shanks themselves are designed identically for all types.
–¬†¬†¬†¬† Shank type F has two holes for the coolant supply (F = fluid) on the face contact for use in two installation positions (offset by 180¬∞).
–¬†¬†¬†¬† Shank type H has a primary coolant hole for the main supply and a secondary coolant hole for an intermediate tool position on the face contact (H = half). For PTI type H holders an installation position offset by 180¬∞ is not possible.
–¬†¬†¬†¬† Shank type A has two holes on the face contact for the primary coolant supply and additional two holes for supplying the tool holder (driven tool) with sealing air (A = air). An installation position offset by 180¬∞ is possible. A spring-type straight pin belongs to the holder and avoids incorrect insertion.

Abstract
This document specifies the dimensions of polygonal taper shanks with flat contact surface (PTI). These shanks are the tool-side part of the interface to the (in cutting process non-rotating) tool carrier of machine tools (e.g. turret lathes, turning centres).
This document specifies three types of tool-side interface types, which differ at the face contact. The tool shanks themselves are designed identically for all types.
-     Shank type F has two holes for the coolant supply (F = fluid) on the face contact for use in two installation positions (offset by 180°).
-     Shank type H has a primary coolant hole for the main supply and a secondary coolant hole for an intermediate tool position on the face contact (H = half). For PTI type H holders an installation position offset by 180° is not possible.
-     Shank type A has two holes on the face contact for the primary coolant supply and additional two holes for supplying the tool holder (driven tool) with sealing air (A = air). An installation position offset by 180° is possible. A spring-type straight pin belongs to the holder and avoids incorrect insertion.
