Spindle Test Module
Overview
Warning - Due to required accessories, this module is not for use in Class I
Division 2 hazardous locations. Restrictions apply when used in ATEX zone 2
hazardous locations. Reference this manual's Appendix D, Safety Instructions for
details.
The Microlog’s Spindle Test Module is used by personnel who wish to perform before-
and-after type vibration level tests for pass / fail conformance in accordance with an
appropriate ISO, ANSI, API or other standard, including vibration level standards defined
by the user.
Spindle Test settings are specified in “test template files” that are transferred to the
Microlog. These pre-configured test templates measure machinery vibration in
accordance with a recognized international standard (e.g., ISO, ANSI, API, etc.). Each
test template defines a standard’s vibration level measurements for a specific
machinery classification, and the measurement grade levels to which measurement
results are compared.
You may apply these conventional test templates with their standardized measurement
grade settings, or you may use a host computer with the CC Setup Generator software
to modify the standardized test template settings to more accurately apply to your
machinery vibration conformance surveys. In addition, you may use the Setup software
to set up custom test templates specific to your machinery conformance survey needs.
The Spindle Assessment kit has been developed in conjunction with the SKF Machine
Tool Precision Services and is designed to perform nine tests on the machine tool
spindles:
Imbalance - Determine imbalance condition utilizing Microlog and sensor
Mechanical condition - Determine mechanical conditions utilizing Microlog and sensor
Bearing condition - Determine bearing condition utilizing Microlog and sensor
Tool nose run-out - Determine tool nose run-out utilizing Microlog and an external
pull force gauge
Clamp force - Determine actual drawbar force utilizing Microlog and a clamp force
gauge
EM distance - Determine actual EM distance utilizing Microlog and a depth micrometer
Belt tension - Determine belt tension utilizing Microlog and an external belt tension
gauge
Speed accuracy - Determine speed accuracy utilizing Microlog and a tachometer
Resonance frequency - Determine resonance frequency utilizing Microlog, sensor, and
a tachometer
