Описание (английский):

ISO 3442-2:2005 specifies the sizes for interchangeability of self-centring, power-operated chucks with two-piece jaws (tongue and groove type) and describes, by reference to ISO 230-1, the geometric tests for such chucks. It also specifies the tolerances which apply to these tests.

Overview

ISO 3442-2:2005 - Machine tools - Dimensions and geometric tests for self-centring chucks with two-piece jaws - Part 2 covers power‑operated, self‑centring chucks with tongue‑and‑groove (two‑piece) jaws. The standard specifies sizes for interchangeability, the geometric tests (by reference to ISO 230-1) used to verify chuck geometry and rotational accuracy, and the tolerances that apply to those tests. All dimensions and tolerances are given in millimetres (mm).

Key Topics and Requirements

Scope: Verification focuses on rotational accuracy of the chuck and position of top‑jaw assembling elements. The standard explicitly does not cover dynamic aspects such as balancing, gripping power or balancing procedures.

Interchangeability sizes: Nominal chuck diameters covered include typical sizes from 100 mm to 800 mm (see the standard’s Table 1 for full dimensions and mounting/thread details).

Referenced test code: Geometric tests are described by reference to ISO 230-1:1996 (Test code for machine tools - geometric accuracy).

Geometric tests (G01–G05):

G01 / G02 - Checking spindle/face-plate radial run‑out and camming (tolerance 0.005 mm).
G1 / G2 - Radial run‑out of outer surface and camming of chuck face (tolerances vary by nominal diameter: 0.02–0.06 mm depending on size band).
G3 - Equidistance between top jaw locating key slots (0.03–0.12 mm).
G4 - Deviation between top of master jaws and mounting chuck face (0.03–0.10 mm).
G5 - Deviation between top jaw locating centre‑line and a parallel plane through chuck centre‑line (0.05–0.20 mm).

Measurement practice:

Primary instrument: dial gauge.
Tests may be performed with the chuck mounted on a test spindle or using a measuring machine; results can differ due to spindle‑nose tolerances.
Several tests require the chuck tightened with base/master jaws locked on a dummy piece and clamping force as specified by the manufacturer.

Accuracy class: The document specifies a single accuracy class; specially adjusted non‑interchangeable jaws must be marked.

Applications and Users

Who uses it: machine‑tool manufacturers, chuck designers and manufacturers, QA/metrology labs, maintenance teams, and procurement/specification engineers.

Practical uses:

Ensuring interchangeability of top jaws between chucks.
Specifying acceptance criteria for incoming chucks and routine quality checks.
Supporting accurate jaw mounting and pre‑setting on jigs separate from the machine spindle to maintain machining precision.
