Full title and description

ISO 4703:2001 — Test conditions for surface grinding machines with two columns — Machines for grinding slideways — Testing of the accuracy. This International Standard defines test conditions and acceptance-related procedures used to verify the geometric and machining accuracy of two-column surface grinding machines designed for grinding slideways (guideways).

Abstract

Specifies geometric tests, machining tests and checks for the accuracy and repeatability of positioning axes on general-purpose and normal-accuracy two-column surface grinding machines used for grinding slideways. The standard describes installation and preliminary conditions, measurement methods and permissible deviations (acceptance criteria) for verifying machine accuracy.

Scope

Applies to two-column (dual-column) surface grinding machines used specifically for grinding slideways/guideways. The standard focuses on verification of machine accuracy through defined geometric and machining tests, including checks of installation conditions, axis accuracy, and repeatability of numerically controlled positioning where applicable. It does not cover machine running characteristics unrelated to accuracy testing (e.g., dynamic running behaviour). The ISO record also indicates a project to revise/replace this edition (an AWI under development).

Key topics and requirements

• Preliminary installation and environmental conditions required before accuracy testing (foundation, leveling, temperature stabilization).
• Geometric tests for straightness, squareness, parallelism and other positional errors relevant to slideway grinding.
• Machining tests (test-piece generation) to evaluate practical grinding performance and resulting deviations on finished surfaces.
• Accuracy and repeatability tests for numerically controlled positioning axes where fitted.
• Definition of permissible deviations / acceptance limits and reporting format for test results.
• Annexes and normative references to facilitate consistent measurement methods and terminology.

These topic groupings reflect the standard’s structure as summarized in product catalogs and the ISO entry.

Typical use and users

Used by machine tool manufacturers (design and quality teams), production and inspection departments, test laboratories, acceptance/commissioning engineers, purchasers specifying acceptance criteria, maintenance teams diagnosing machine accuracy issues, and conformity assessment bodies performing independent verification of grinding machines intended for slideway grinding.

Related standards

Closely associated with ISO machine-tool test-code standards (for example ISO 230 series for geometric and machining tests), and other ISO/TC 39/SC 2 publications covering test methods for machine-tool accuracy and performance. National adoptions or identical/related documents (e.g., BS ISO 4703) provide harmonized national implementations.

FAQ

Q: What is this standard?

A: ISO 4703:2001 specifies test conditions and methods for assessing the accuracy of two-column surface grinding machines used for grinding slideways (guideways).

Q: What does it cover?

A: It covers preliminary installation conditions, geometric and machining tests, accuracy and repeatability checks for positioning axes, and permissible deviations/acceptance criteria for two-column surface grinding machines used for slideway grinding. It is focused on verification of accuracy rather than dynamic running characteristics.

Q: Who typically uses it?

A: Machine tool manufacturers, inspection and test laboratories, commissioning and maintenance engineers, purchasers specifying acceptance checks, and conformity assessment bodies. These users apply the standard during factory acceptance, site commissioning and periodic verification of machine accuracy.

Q: Is it current or superseded?

A: The 2001 edition (Edition 3) is published and — according to ISO’s bibliographic record — was last reviewed and confirmed in 2023 and therefore remains the current published edition; ISO also lists a work item (ISO/AWI 4703) indicating revision activity under development. Users should check ISO or their national standards body for the latest status before purchase or citation.

Q: Is it part of a series?

A: It sits within the machine-tool testing and acceptance domain handled by ISO/TC 39/SC 2 and is commonly used alongside the ISO 230 test-code series (Test code for machine tools) and related ISO machine-tool accuracy documents.

Q: What are the key keywords?

A: surface grinding machine; two-column; slideways; guideways; accuracy testing; geometric tests; machining tests; repeatability; ISO 4703; machine-tool test code.
