Full title and description

St ISO 2407-2024 — Test conditions for internal cylindrical grinding machines with horizontal spindle — Testing of accuracy. This International Standard specifies test conditions, test methods and tolerances for verifying the geometric accuracy, positioning accuracy and machining accuracy of internal cylindrical grinding machines with a horizontal spindle (general-purpose and normal-accuracy machines), whether or not fitted with a facing wheelhead slide.

Abstract

This document gives detailed geometric, positioning and machining tests for internal cylindrical grinding machines with horizontal spindles, and it specifies the applicable tolerances for those tests. It is written with reference to ISO 230‑1, ISO 230‑2 and ISO 230‑7 and defines terminology and axis designation (with reference to ISO 841). The standard is restricted to verification of accuracy and does not cover machine operation characteristics such as vibration, abnormal noise or the checking of speeds and feeds.

Scope

Applies to general-purpose and normal-accuracy internal cylindrical grinding machines with horizontal spindles. The standard specifies: terminology and axis designation (in line with ISO 841); geometric tests; positioning tests; machining tests; and the tolerances applicable to those tests. It is limited to accuracy verification and explicitly excludes dynamic/operational checks such as vibration, abnormal noise or detailed performance checks of speeds and feeds. The document references and aligns with ISO 230‑1, ISO 230‑2 and ISO 230‑7 for broader machine-tool testing context.

Key topics and requirements

• Definitions and terminology for components and axes of internal cylindrical grinding machines (reference to ISO 841).
• Geometric tests to check form and alignment of machine elements used in internal cylindrical grinding.
• Positioning and repeatability tests for axes relevant to internal grinding processes.
• Machining tests (test pieces and procedures) to assess actual grinding accuracy under specified conditions.
• Specified tolerances for the above tests, with acceptance criteria for general-purpose and normal-accuracy machines.
• References to ISO 230 series (machine tool testing) for test environment and measurement practices.
• Exclusions: this standard does not cover testing of machine operation (vibration, abnormal noise, stick‑slip, etc.) or the verification of speeds/feeds which are normally checked separately.

Typical use and users

Used by machine tool manufacturers, factory quality and inspection teams, independent testing laboratories, commissioning engineers, maintenance teams and procurement specialists who need to verify the accuracy and acceptance of internal cylindrical grinding machines with horizontal spindles. Also used by standards committees and technical authors drafting machine-tool acceptance and maintenance procedures. (Context and scope based on ISO 2407:2024 requirements and references.)

Related standards

Key related and referenced standards include ISO 230‑1 (Test code for machine tools — Part 1: Geometric accuracy of machines operating under no-load or quasi-static conditions), ISO 230‑2, ISO 230‑7, and ISO 841 (terms and designation of axes for machine tools). ISO 2407:2024 replaces and updates the earlier ISO 2407:1997 (and its amendment ISO 2407:1997/Amd 1:2016).

FAQ

Q: What is this standard?

A: ISO 2407:2024 is an International Standard that specifies test conditions, test methods and tolerances for verifying the accuracy of internal cylindrical grinding machines with horizontal spindles (edition 4, published 30 August 2024).

Q: What does it cover?

A: It covers definitions/terminology, axis designation, geometric tests, positioning tests, machining tests and the corresponding acceptance tolerances for general-purpose and normal-accuracy internal cylindrical grinding machines with horizontal spindles. It excludes checks of machine operation (vibration, abnormal noise) and the verification of speeds and feeds.

Q: Who typically uses it?

A: Machine tool manufacturers, factory acceptance/inspection teams, independent test laboratories, commissioning and maintenance engineers, procurement specialists and standards bodies use this standard for acceptance testing, accuracy verification and machine commissioning.

Q: Is it current or superseded?

A: Current — ISO 2407:2024 (4th edition) is the active standard published in 2024 and supersedes ISO 2407:1997 (and its amendment).

Q: Is it part of a series?

A: It is closely linked with the ISO 230 series of machine-tool test codes (notably ISO 230‑1, ISO 230‑2 and ISO 230‑7) and uses ISO 841 for axis designation; practitioners typically use these documents together when performing comprehensive machine-tool testing.
