带平面接触面的多边形转台接口第2部分:F、H、A和X型用于F、H和A型刀柄的接收器

[中文适用范围]： 本文件规定了具有平面接触表面的多边形锥度接收器（PTI）的尺寸。这些接收器是机器一侧与机床中的刀具载体（例如 turret lathes, turning centres）接口的部件。该文件规定了四种机器一侧的接口类型，其区别在于面接触部分。所有类型的接收器用于容纳工具夹持端的部分都是相同设计的。 receivers are the machine-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 four types of machine-side interface types, which differ at the face contact. [外文原描述]： This document specifies the dimensions of polygonal taper receivers with flat contact surface (PTI). These receivers are the machine-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 four types of machine-side interface types, which differ at the face contact. The bores for receiving the tool shanks themselves are designed identically for all types. — Receiver type F has one hole for the coolant supply (F = fluid); PTI-F type tool holder can be installed in 0°- and 180°-position. — Receiver 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. — Receiver type A has one hole on the face contact for the primary coolant supply and one additional hole for supplying the tool holder (driven tool) with sealing air (A = air). Two more bores allow the installation of PTI-A holders with spring-type straight pin in 0°- and 180°-position. — Receiver type X has a primary coolant hole for the main supply and a secondary coolant hole for an intermediate tool position on the face contact. In addition, the type X receiver has one hole for supplying the tool holder (driven tool) with sealing air and two bores for the 0°- and 180°-position of the spring-type straight pin of PTI-A holders.
