Polygonal interface with flange contact surface Part 1. Shank size and marking

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).
