Elle ne traite que du contrôle de la précision de la machine. Elle ne concerne ni l'examen de son fonctionnement (vibrations, bruits anormaux, points durs dans les déplacements d'organes, etc.), ni celui de ses caractéristiques (vitesse, avances, etc.), examens qui doivent, en général, précéder celui de la précision.

Overview
ISO 2423:1982 - "Acceptance conditions for radial drilling machines with the arm adjustable in height - Testing of accuracy" is an ISO standard that defines how to verify the accuracy of general-purpose, normal-accuracy radial drilling machines whose arm can be adjusted in height. This second edition (1982) cancels ISO 2423:1974 and focuses exclusively on accuracy verification (geometrical and practical tests) and the corresponding permissible deviations. It does not cover running characteristics (vibration, noise, speeds/feeds) which should be checked before accuracy testing.
Key topics and technical requirements
- Scope and test reference: Uses ISO/R 230 (Machine tool test code) for test methods, installation, and measuring practices. All dimensions and tolerances are given in millimetres and inches.
- Geometrical tests: Verifies features such as base-plate flatness and levelling, arm parallelism and radial movement, saddle movement, spindle squareness and vertical travel squareness. Tests are normally performed with the arm and saddle at mid-travel unless otherwise specified.
- Spindle checks: Includes measurement of spindle internal-taper run-out - typical permissible values in the standard are 0.025 mm (0.001 in) at the taper mouth and 0.05 mm (0.002 in) at 300 mm from the spindle nose. Squareness of the spindle axis to the base plate is also specified.
- Practical (load) tests: Defines an axial-load deflection test that measures spindle axis deflection under a specified axial force applied at the spindle nose (instead of an actual drilling test). The required test load is either manufacturer-specified or selected using the annex graph that relates axial force to drilling capacity.
- Instruments and measurement: Typical measuring equipment referenced includes precision levels, straightedges, dial gauges, test mandrels, gauge blocks and load cells. A calibration sheet for test instruments is expected.
- Permissible deviations: The standard lists permissible deviations for each test item and gives observations on test set-up (e.g., arm and saddle locked, measuring positions).
Applications and users
- Who uses it: machine-tool manufacturers, quality/acceptance inspectors, test laboratories, machine tool purchasers, service engineers and dealers.
- Practical uses: acceptance testing of new radial drilling machines, factory inspection, quality assurance during installation, and contractual acceptance criteria when buying or specifying radial drilling equipment.
- Benefit: Provides objective, repeatable accuracy tests and clear permissible deviations to support acceptance, warranty checks and quality control.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of
national Standards institutes (ISO member bedies). The work of developing Inter-
national Standards is carried out through ISO technical committees. Every member
body interested in a subject for which a technical committee has been set up has the
right to be represented on that committee. International organizations, governmental
and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the ISO Council.
International Standard ISO 2423 was developed by Technical Committee ISO/TC 39,

The standard outlines geometrical and practical tests for these machines and provides permissible deviations. It focuses on verifying the accuracy of the machine and does not cover testing for machine running issues such as vibrations or abnormal noises. Additionally, the standard does not address machine characteristics like speeds and feeds, as these should be checked before assessing accuracy.
