ISO 2433-1999 PDF

Full title and description

St ISO 2433-1999 — Machine tools — Test conditions for external cylindrical and universal grinding machines with a movable table — Testing of accuracy. This international standard specifies test procedures, acceptance tolerances and terminology for verifying the geometric accuracy and positioning performance of external cylindrical and universal grinding machines equipped with a movable table.

Abstract

ISO 2433:1999 defines engineering and machining tests to assess the accuracy and repeatability of external cylindrical and universal grinding machines with a movable table. It covers geometric tests (straightness, parallelism, squareness, runout), positioning and repeatability checks, and machining tests used for acceptance and verification. The standard applies limits on machine size (swing diameter and distance between centres) and explicitly excludes running/operational tests such as vibration or speed/feeding characteristic tests.

Scope

This standard applies to general-purpose and normal-accuracy external cylindrical and universal grinding machines with a movable table having a swing diameter up to 800 mm and a distance between centres up to 4 000 mm. ISO 2433:1999 is restricted to verification of machine accuracy (geometric and positioning performance) and does not cover running tests (vibration, abnormal noise, stick‑slip) or machine operating characteristics (speeds, feeds), which should normally be checked prior to accuracy testing. The standard refers to and complements test methods and conventions given in related standards (for example ISO 230 series and ISO 841 for axis designation).

Key topics and requirements

• Definition of terminology and axis designation for the main machine elements (references ISO 841).
• Geometric tests: straightness, flatness, parallelism, squareness and angular errors for relevant axes and components.
• Positioning accuracy and repeatability checks for table and wheelhead movements.
• Machining tests to evaluate practical accuracy under cutting conditions (indicative machining trials and evaluation criteria).
• Specified applicability limits: machines with swing diameter ≤ 800 mm and distance between centres ≤ 4 000 mm.
• Exclusion of running tests and machine characteristic measurements from the scope of accuracy verification.
• Informative annexes (terminology in additional languages and explanatory material).

Typical use and users

Used by machine tool manufacturers, quality and inspection laboratories, end‑users accepting or commissioning cylindrical grinding machines, service and maintenance engineers, and organizations performing conformity/acceptance testing. Typical applications include factory acceptance tests (FAT), after‑repair verification, purchase acceptance, and periodic accuracy checks as part of quality systems for precision manufacture.

Related standards

Standards commonly used alongside ISO 2433:1999 include ISO 230-1 and ISO 230-2 (test code for machine tools), ISO 841 (axis designation), and other ISO machine tool test standards. ISO 2433:1999 revises earlier editions (ISO 2433:1984 and ISO 2433:1973) and is part of the body of ISO/TC 39/SC 2 standards for machine tool testing and verification.

Q: What does it cover?

A: It covers terminology, geometric and positioning accuracy tests, repeatability and representative machining tests for acceptance and verification. It applies to machines with swing diameter up to 800 mm and distance between centres up to 4 000 mm and excludes running/operational tests and general machine characteristic measurements.

Q: Who typically uses it?

A: Machine tool manufacturers, inspection and calibration laboratories, purchasers and end‑users performing acceptance tests, service engineers, and quality managers involved in precision grinding applications.

Q: Is it current or superseded?

A: The 3rd edition, ISO 2433:1999, is published and was officially reviewed and confirmed as current (stage 90.93) on 17 May 2022. As of that confirmation the 1999 edition remains the current published version.

Q: Is it part of a series?

A: It forms part of the family of ISO standards addressing machine tool testing and verification (often used together with ISO 230 series) and belongs to the work of ISO/TC 39/SC 2. It is also the successor to earlier ISO 2433 editions (1973 and 1984).
