“Revolution in Spindle Measurement” Video Updated and Now Online

Aug. 25, 2009 - PRLog -- An updated video on machine tool spindle measurement features international experts Dr. Robert Hocken, Dr. James Tlusty, and Dr. James Bryan describing modern, high-tech spindle measurement methods and their importance. The original video has been updated with the latest version of the Lion Precision Spindle Error Analyzer and can now be viewed online at www.spindleanalysis.com. In the 12-minute video, the experts describe the needed transition from spindle measurement methods developed in the 1930s to newer methods using noncontact sensors and computer analysis. The older Schlesinger method used a dial indicator to measure a machine tool spindle while it was turned very slowly, often by hand. Modern methods using high-performance noncontact sensors, temperature sensors and computer data acquisition, enable measurement of the spindle at full operating speeds in multiple axes and with temperature data to show thermal dependencies.

Compliance with international standards such as ASME B5.54 and B5.57 and ISO 230-7 require these multi-axis spindle tests. The video discusses the advantages of machine tool characterization of capability and specifications before a part is made, including reduced production costs, verification of machine capability before acceptance and improved machine assignment dependent on critical part parameters.

Lion Precision, established in 1958, pioneered commercially available noncontact sensing systems. The company’s Spindle Error Analyzer is the dominant solution for spindle measurements that comply with international standards and is used by machine tool builders and users across the globe.

The company provides high-performance capacitive and eddy-current displacement sensors for industries such as machine tool, semiconductor, disk drive, automotive, packaging, and university and national laboratory research.
