Описание (английский):

ISO 7388-2:2007 specifies the dimensions of tool shanks with a 7/24 taper of shank form J (with two possible additions for each) for automatic tool changers, used on machines having an automatic gripping system for feeding tools from the magazine to the spindle and vice-versa. These tools are designed with the most important dimensions for use in spindle noses according to ISO 9270.

Overview

ISO 7388-2:2007 defines the dimensions and designation of tool shanks with a 7/24 taper for automatic tool changers - specifically shank forms J, JD and JF. It standardizes key geometrical features, tolerancing principles (millimetre units), optional coolant and data-medium provisions, and the recommended designation format for compatibility with magazine-to-spindle automatic gripping systems and spindle noses per ISO 9270.

Key topics and technical requirements

Shank forms and options

Form J: basic shank geometry and critical dimensions (see tables for shank numbers/sizes).
Form JD: adds a central through-hole (e.g., for internal coolant) subject to core diameter constraints relative to the retention knob thread.
Form JF: adds two rear flange holes for inner coolant supply; auxiliary connecting bore must be sealed for operation up to 5 MPa.

Dimensions and tolerances

All dimensions in millimetres; tolerancing follows ISO 8015 and general tolerances per ISO 2768‑1 and ISO 2768‑2 when not individually specified.
Detailed tables specify diameters, lengths, radii and angle (7/24 taper alpha) for shank numbers (30, 40, 45, 50, 60).

Data medium provision

Optional recesses for a data medium (tool ID / chip) are defined with fitting position and dimensions.

Material and heat treatment

Guidance to select heat treatment, hardness and case depth to meet strength, toughness and wear requirements (no prescriptive metallurgy).

Designation

Clear naming convention: “Tool shank ISO 7388-2 - [Form] [Size] - [D if data medium]” (e.g., Tool shank ISO 7388-2 - J 40 - D).

Applications and users

Who uses it

CNC machine tool manufacturers, toolholder and shank manufacturers, tooling suppliers, design/production engineers, quality and metrology teams.

Practical use cases

Ensuring interchangeability of tool shanks in automatic tool changers and spindle noses.
Specifying shanks compatible with internal coolant systems (JF/JD) and tool identification/data media.
Designing retention knob interfaces and ensuring mechanical and pressure-sealing performance for coolant-fed tooling.
