    Spindle Error Analyzer - lionPrecision Vietnam-ANS Vietnam 

    Đăng bởiAdmin

    in our Spindle Metrology LinkedIn Group to discuss spindle measurement and performance.

    Spindle Error Analyzer (SEA)

    The Spindle Error Analyzer measures and analyzes spindle error motions (dynamic and thermal) in accordance with ANSI/ASME, ISO, and JIS standards. These error motions create form errors in manufactured workpieces. The analysis is also useful in non-machinetool applications where spindle performance is a critical factor.

    Part Form Errors

    Form errors in manufactured parts are directly proportional to error motions of the spindle. How far away from the correct location

    is the cutting tool actually contacting the workpiece?

    The Spindle Error Analyzer measures the motions of a machine tool spindle at operating speeds. It then analyzes and reports error motions that decrease part quality. These measurements aid in troubleshooting, prevent unnecessary spindle rebuilds (a very common occurrence), and result in increased part quality and decreased scrap.

    • Discover problems before you make bad parts.
    • Qualify/Test machine performance before acceptance.
    • Find root cause of machining errors

    A complete measurement system consisting of:

    • High-resolution capacitive displacement sensors
    • Precision spherical or cylindrical targets
    • Robust sensor mounting hardware
    • Data acquisition components
    • Proprietary software for error motion analysis


    Eric Marsh, Ph.D., Motion Dynamics Research Lab at The Pennsylvania State University

    "Troubleshooting by simply looking at unsatisfactory and out-of-tolerance parts is difficult at best. The use of proper measurement tools provides the quickest and most accurate path to identifying causes and solving problems."


    Jim Bryan, Ph.D. formerly of LLNL

    "Routinely measure machines in your shop to know their health and condition before they make bad parts, before they breakdown."

    Predict and prevent part errors

    Machine evaluation enables manufacturers to predict and prevent part errors such as:

    • Surface finish
    • Feature location
    • Roundness

    Find and eliminate spindle error motion sources

    • Out of round bearing components
    • Misaligned bearing seats
    • Bearing wear
    • Improper preload
    • Structural vibration
    • Inadequate stiffness
    • Resonant machine frequencies

    Specific measurements required by international standards

    Synchronous and Asynchronous measurements of

    • Radial error motion
    • Axial error motion
    • Tilt error motion
    • Total Indicator Reading (TIR, Runout)

    See this excellent description of rotary axis error motions.

    Compliant with international standards

    The Spindle Error Analyzer performs tests in compliance with these standards:
    ANSI/ASME Standard B5.54-2005, "Methods for Performance Evaluation of CNC Machining Centers"
    ANSI/ASME B5.57-1998 "Methods for Performance Evaluation of CNC Turning Centers"
    ANSI/ASME B89.3.4-2010, "Axes of Rotation, Methods for Specifying and Testing"
    ISO230-3, Test Code for Machine Tools Part 3, "Determination of Thermal Effects"
    ISO230-7, Test Code for Machine Tools Part 7, "Geometric Accuracy of Axes of Rotation "
    JIS B 6190-7, Test Code for Machine Tools Part 7, "Geometric Accuracy of Axes of Rotation"
