Full title and description

Machine tools — Test conditions for surface grinding machines with vertical grinding wheel spindle and reciprocating table — Testing of the accuracy (ISO 1985:2015). This International Standard specifies geometric and machining tests and the applicable tolerances for general-purpose, normal-accuracy manually and numerically controlled surface grinding machines with a reciprocating table and vertical wheel spindle.

Abstract

ISO 1985:2015 defines tests (referencing ISO 230‑1 and ISO 230‑7) for verification of geometric accuracy and machining performance of surface grinding machines with a vertical grinding wheel spindle and a reciprocating table. It excludes machines with fixed or rotating tables and machines whose wheelhead has longitudinal traverse; it also does not cover operational checks such as vibration or speed/ feed characteristics.

Scope

Specifies test conditions, procedures and tolerances for checking the accuracy (geometric and machining) of surface grinding machines that have a vertical grinding wheel spindle and a reciprocating table. The standard is intended for general-purpose, normal-accuracy machines whether manual or NC; it is not applicable to machines with fixed or rotating tables or to wheelheads with longitudinal traverse. Operational characteristics (vibration, noise, speeds/feeds) are outside the scope.

Key topics and requirements

• Definitions and terminology for principal machine components and axis designation (with reference to ISO 841).
• Geometric accuracy tests (straightness, flatness, squareness/orthogonality, positional accuracy) specific to reciprocating-table, vertical-spindle surface grinders.
• Machining tests to assess finish and dimensional performance under typical operating conditions.
• Specified tolerances corresponding to the above tests for general-purpose, normal-accuracy machines.
• Reference to ISO 230‑1 and ISO 230‑7 for general test principles and additional machine tool tests.

Requirements focus on verification procedures and tolerances rather than dynamic or operational checks.

Typical use and users

Used by machine tool manufacturers, quality and metrology laboratories, inspection and maintenance teams, purchasers of surface grinding machines, and standards/technical committees. It supports acceptance testing, in-factory verification, and periodic accuracy checks for relevant surface grinding equipment.

Related standards

Closely related to ISO 230‑1 and ISO 230‑7 (general test conditions and tests for machine tools). ISO 1985 has earlier editions/versions (ISO 1985:1974 and ISO 1985:1985) that were withdrawn and subsequently replaced by ISO 1985:2015.

FAQ

Q: What is this standard?

A: ISO 1985:2015 is an International Standard that specifies test conditions and tolerances for checking the accuracy of surface grinding machines with a vertical grinding wheel spindle and a reciprocating table.

Q: What does it cover?

A: It covers geometric and machining accuracy tests and specified tolerances for general-purpose, normal-accuracy, manual and NC surface grinding machines with a reciprocating table and vertical spindle; it excludes fixed/rotating-table machines and dynamic/operational checks.

Q: Who typically uses it?

A: Manufacturers, test and calibration laboratories, inspection/maintenance personnel, buyers of grinding machines, and standards bodies use it for acceptance testing and verifying machine accuracy.

Q: Is it current or superseded?

A: ISO 1985:2015 is the current published edition (Edition 4, published March 2015). Earlier editions (including 1985 and 1974 versions) were withdrawn and replaced by the 2015 edition; the ISO bibliographic record shows the 2015 edition as published and confirmed on review.

Q: Is it part of a series?

A: It is a standalone ISO standard addressing a specific class of surface grinding machines, but it cross-references and should be used alongside general machine‑tool test standards such as ISO 230‑1 and ISO 230‑7.

Q: What are the key keywords?

A: Surface grinding, accuracy testing, reciprocating table, vertical spindle, machine tools, tolerances, ISO 1985.
