Summary: This standard specifies the size of the taper shank series for automatic tool change and manual tool change machines such as lathes, drill presses, milling machines, turning centers and grinding machines, and multi-pyramidal interfaces with flange contact surfaces. Flange parts with grooves can be used for automatic tool change. The shank is achieved by means of an (expandable) fan block, by tightening the circular arc groove in the hole or by tightening the internal thread with a center bolt. Torque transmission is achieved by a locking device (polygonal pyramid).

Foreword

GB/T 32557 "Polygonal interface with flange contact surface" is divided into two parts. - Part 1. Shank size and marking; - Part 2. Mounting hole size and marking. This part is part 1 of GB/T 32577. This part is drafted in accordance with the rules given in GB/T 1.1-2009. This part uses the translation method equivalent to ISO 26623-1..2008 "Polygonal interface with flange contact surface Part 1. Shank Inch and mark "(English version). In this part of the normative reference to the international documents have a consistent correspondence between the following documents. --- GB/T 9145-2003 Ultimate dimensions of normal thread, preferred series (ISO 965-2..1998, MOD) --- GB/T 1804-2000 General tolerances Tolerances of linear and angular dimensions without tolerances (ISO 2768-1. 1989, eqv) This part is made by the China Machinery Industry Federation.

1 Scope

This part of GB/T 32577 specifies the use of automatic tool changers and manual tool changers (eg lathes, drills, milling machines, milling centers and grinding Bed), with a flange contact surface of the multi-pyramid interface taper shank series size. Flange parts with trenches can be used for automatic tool change. The handle is passed through (expandable) fan-shaped blocks, tighten the hole in the circular groove or use Center Bolt Tightening Internal Thread. Torque transmission is achieved by a latch (polygonal pyramid).
