Polygonal turret interface with flat contact surface - Part 1: Shanks of type F, H and A

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.

Polygonal turret interface with flat contact surface - Part 1: Shanks of type F, H and A

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.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
