ISO 1986-1-2014 PDF

Full title and description

ISO 1986-1:2014 — Test conditions for surface grinding machines with horizontal grinding wheel spindle and reciprocating table — Testing of the accuracy — Part 1: Machines with table length of up to 1 600 mm. This International Standard specifies geometric and machining tests and the corresponding tolerances for verification of the accuracy of general‑purpose and normal‑accuracy surface grinding machines with a horizontal wheel spindle and a reciprocating table (table length ≤ 1 600 mm).

Abstract

ISO 1986-1:2014 defines test conditions, test procedures and applicable tolerance limits for accuracy testing of surface grinding machines that have a horizontal grinding wheel spindle and a reciprocating table with a table length up to 1 600 mm. It references ISO 230‑1 for general machine‑tool test principles, provides terminology for principal machine components and indicates axis designation with reference to ISO 841. The standard is limited to verification of accuracy and does not cover operational characteristics (e.g., vibration, abnormal noises) or machine performance parameters such as speeds and feeds.

Scope

This part of ISO 1986 applies to surface grinding machines with a horizontal grinding wheel spindle and a reciprocating table having a table length of up to 1 600 mm. It covers the tests necessary to verify geometric accuracy and relevant machining tests, and it specifies the tolerances applicable to those tests. It is not applicable to machines with fixed or rotating tables, nor to machines having longitudinal traverse of the wheelhead. It does not cover dynamic or operational checks (vibrations, abnormal noises, stick‑slip, etc.) or general machine performance characteristics (speeds, feeds), which should be checked prior to accuracy testing.

Key topics and requirements

• Definitions and terminology for principal components of surface grinding machines; axis designation referenced to ISO 841.
• Geometric tests to verify axes straightness, squareness, parallelism and table/slide geometry appropriate for reciprocating‑table machines.
• Machining tests simulating typical grinding operations and evaluation of workpiece results against specified tolerances.
• Reference to ISO 230‑1 for general machine‑tool test procedures and environmental/test conditions.
• Specified tolerance limits and acceptance criteria for the range of tests covered in the standard.
• Limitations and exclusions: scope limited to accuracy verification; excludes tests for machine operation dynamics and non‑accuracy performance parameters.

Typical use and users

Used by machine tool manufacturers, quality and inspection engineers, testing and calibration laboratories, OEMs and end users of surface grinding machines for acceptance testing, factory inspection, periodic verification and commissioning. Also used by standards committees and procurement/specification writers to define contractual acceptance criteria for reciprocating‑table surface grinders with horizontal spindles.

Related standards

Commonly 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) and ISO 841 (Designation of axes). ISO 1986-1:2014 replaces earlier editions such as ISO 1986-1:2001 and is connected historically to ISO 1986 (earlier acceptance conditions publications for surface grinding machines).

FAQ

Q: What is this standard?

A: ISO 1986-1:2014 is an ISO International Standard that specifies test conditions, procedures and tolerances for verifying the accuracy of surface grinding machines with a horizontal grinding wheel spindle and a reciprocating table up to 1 600 mm table length.

Q: What does it cover?

A: It covers geometric and machining accuracy tests and the applicable tolerance limits for machines within its scope. It provides terminology and axis designation guidance (referencing ISO 841) and refers to ISO 230‑1 for general test principles. It does not cover machine dynamic behaviour or general performance parameters (speeds, feeds, vibration tests).

Q: Who typically uses it?

A: Machine tool manufacturers, inspection and quality engineers, calibration and testing laboratories, procurement/specification writers, and maintenance/commissioning teams involved with surface grinding machines.

Q: Is it current or superseded?

A: Current. ISO 1986-1:2014 (Edition 2, published June 2014) replaced ISO 1986-1:2001. The standard was reviewed and confirmed in 2025 and therefore remains the current edition.

Q: Is it part of a series?

A: Yes. It is Part 1 of the ISO 1986 series addressing test/acceptance conditions for surface grinding machines (historically related to ISO 1986 and later ISO 1986-1 editions). Other related parts or regional/adopted documents may exist for different machine types or table configurations.

Q: What are the key keywords?

A: surface grinding, grinding machine, horizontal spindle, reciprocating table, accuracy testing, tolerances, ISO 230-1, ISO 841, table length 1600 mm.
