Lion Precision has been measuring machine-tool spindle thermal growth and error motions in multiple axes for over ten years. To address the increasingly stringent requirements for micro-machining in precision tools, the company adapted its technology to target smaller scale measurements.
The micromachining Spindle Error Analyzer (SEA) uses smaller versions of the noncontact probes, probe mounts, and masterball targets in the earlier design. Using standard SEA software, the new version can perform ANSI and ISO standard tests of spindle performance. The new SEA system measures spindles at operational speeds up to 300,000 RPM with resolutions less than one nanometer.
