hardness tested automatically
A high speed system for hardness testing and grading ball bearings automatically has been developed by Indentec.the system gravity feeds one ball at a time from an adjustable magazine to a stop and support anvil fixed at the testing point under the indenter.
Indentec says that a typical cycle time is about fifteen seconds.maximum and minimum hardnesses, scale conversions, numbers in and out of tolerance, percentage failures, capability indices, etc.
