Foreword

GB/T 10944 "ATC 7.24 cone tool shank" is divided into five sections.

--- Part 1. A, AD, AF, U, UD and UF type shank dimensions and marking;

--- Part 2. J, JD and JF type shank dimensions and marking;

Part --- Section 3. AC, AD, AF, UC, UD, UF, JD and JF type Rivet;

--- Part 4. handles the technical conditions;

--- Part 5. Rivet technical conditions.

This section GB/T Part of 110,944.

This section drafted in accordance with GB/T 1.1-2009 given rules.

This Part replaces GB/T 10944.1-2006 "automatic tool changer with tool shank taper 7.24 Part 40, 45 and 50 handle 1.

Size and taper angle tolerance ", compared with the GB/T 10944.1-2006, the main technical changes are as follows.

--- Modify the name in English;

--- Modify the scope;

--- Modify the normative references;

--- Remove the original tool shank shown (Figure 1), adding a new type A and U-shank icon;

--- Remove the original tool shank size table (Table 1), adding a new type A and U-shank size table;

--- Remove the cone angle tolerances, annotations directly on the chart;

--- Tool shank model increased by 30 and 60, the corresponding type and size has also increased;

--- Increase the size of some models of the tool shank of 40,45,50;

--- Provide increased coolant hole of AD, AF, UD and UF tool handles;

--- Handle increased data chip with holes;

--- Increased material and heat treatment information;

--- Increasing the mark;

--- Increased by reference.

This section uses the translation method identical with ISO 7388-1:2007 "with 7/24 taper for automatic tool changers tool shank - Part 1. A, AD, AF, U, UD and UF type shank types and dimensions "(in English).
