Full title and description

St ISO TR 17243-2-2017 — Machine tool spindles — Evaluation of spindle vibrations by measurements on non-rotating parts — Part 2: Direct-driven spindles and belt-driven spindles with rolling element bearings operating at speeds between 600 r/min and 30 000 r/min. This technical report gives guidance for assessing the severity of spindle vibrations measured on the spindle housing, for use at customer sites and at manufacturers' test facilities.

Abstract

ISO/TR 17243-2:2017 provides criteria and practical guidance for measuring and evaluating vibrations of machine tool spindles by measuring on non-rotating parts (the spindle housing). It applies specifically to direct-driven and belt-driven spindles fitted with rolling element bearings, intended for stationary metal‑cutting machine tools with nominal speeds from 600 r/min up to 30 000 r/min. The report covers preliminary operations, measurement and operational procedures, evaluation parameters, spindle classification and evaluation methods, and includes an informative annex introducing alternative bearing condition assessment techniques. It does not address geometrical axis accuracy, cutting performance issues, speeds outside the stated range, or advanced frequency‑domain analyses such as FFT/envelope techniques.

Scope

This technical report provides information on how to assess the severity of machine tool spindle vibrations measured on the spindle housing. It applies to direct-driven and belt-driven spindles with rolling element bearings assembled on stationary metal‑cutting machine tools and intended to operate at nominal speeds between 600 r/min and 30 000 r/min. The report is intended for testing, periodic verification and continuous monitoring. Exclusions: it does not address geometrical accuracy of axes of rotation, direct assessment of cutting performance (surface finish or dimensional accuracy), spindles operating below 600 r/min or above 30 000 r/min, nor does it prescribe frequency‑domain analyses such as FFT or envelope analyses.

Key topics and requirements

• Measurement on non-rotating parts (spindle housing) as the basis for vibration assessment.
• Defined operating-speed applicability: 600 r/min to 30 000 r/min for direct- and belt-driven spindles.
• Vibration severity criteria and classification of spindles based on measured parameters.
• Recommended preliminary operations and standardized measurement and operational procedures.
• Evaluation parameters to be recorded for testing, periodic verification and continuous monitoring.
• Guidance on interpreting housing vibration relative to spindle condition and suitability for intended machining tasks.
• Informative annex introducing alternative bearing condition assessment techniques.

Typical use and users

Intended users include machine tool manufacturers, test laboratories, OEM service and quality teams, maintenance and reliability engineers, condition-monitoring specialists, and researchers in metal‑cutting and machine tool dynamics. Typical uses are factory acceptance tests, in-service verification, predictive maintenance programs, installation checks at customer sites, and baseline characterization of spindle performance.
