Machine Tool Metrology
Spindle Error Analyzer
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, increase part quality, and prevent unnecessary spindle rebuilds (a very common occurrence).
- 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
Testimonial
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."
Testimonial
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
