Spindle Inspection System Helps to Find Root Causes of Failures

Lion Precision’s SpindleCheck Inspector system provides diagnostic and capability data for all rotating spindles to help shops better manage their machine tools. The system uses non-contact, capacitive sensors with nanometer resolution measure error motion in the machine and surrounding environment. Among other information, this includes intelligence on roughness, roundness, runout, vibration, thermal growth and repeatability across the entire performance range of machine tool. The company says that each of these parameters impacts the final dimensional capability of a machine and its ability to make a part to desired specification.

Ultimately, measuring a rotational spindle can help confirm or eliminate root causes of problems, the company says. For instance, a shop could ensure that a new machine is not a lemon; that production is proceeding optimally; and that maintenance is used to determine the root cause of failures rather than just replacing parts.
