Follow on Google News | ![]() Micro-Machining Performance Evaluation With New Smaller Machine Tool AnalyzerMicro-machining requires high levels of machine performance. A new tool enables users and designers to measure and characterize performance, at operational spindle speeds, in light of thermal growth, vibration, and spindle error motions.
By: Lion Precision With the recent surge in micro-machining spindle designs that minimize error motions, measuring those error motions will continue to present challenges to designers and end users alike. This micro-machining adaptation of a standard instrument is a major step in helping the micro-machining industry get to the next level. The SEA system includes high-resolution noncontact capacitive displacement sensors, precision probe mounts, precise masterball targets with less than 100 nm of roundness error, temperature sensors and software to acquire and analyze the measurements. Results are presented in polar or linear plots and values are listed for synchronous and asynchronous errors, TIR and more. Spindle displacement can be plotted against temperature and RPM to show critical relationships between these variables. For more information on the Micro-Machining version of the Spindle Error Analyzer, visit: www.spindleanalysis.com and click the “Micromachining SEA” button in the left menu, or go directly to: www.lionprecision.com/ In 1958, Lion Precision was the first company to provide capacitive displacement sensors to industry. The company has expanded its product offering to include eddy-current displacement sensors and some application specific sensors for the packaging and PCB industries. # # # Lion Precision manufacturers high performance noncontact displacement/ End
