Ball bearings hardness tested
automatically
A high speed system hardness tests and grades sample batches of fifty or more ball bearings automatically in semi finished or heat treated condition.
A high speed system for hardness testing and grading ball bearings automatically has been developed by Indentec Thought to be the first of its type, it is capable of testing sample batches of fifty or more balls in semi finished or heat treated condition and sorting them individually into in and out of tolerance specimens

Stainless steel robotically hardness tested
Believed to be the first that a digital Vickers hardness testing machine has been adapted for robotic operation, a system has been configured for a Spanish stainless steel plant.
Built into an Indentec digital Rockwell testing machine, 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.
When the Rockwell test has been made, the machine's special software interprets the hardness reading to operate gate and pusher actuators, which direct the ball into either in or out of tolerance channel.
An SPC program in the software provides data processing and recording, with details such as individual, average, maximum and minimum hardnesses, scale conversions, numbers in and out of tolerance, percentage failures, capability indices, etc.
Indentec says that a typical cycle time is about fifteen seconds.
This compares favourably with more conventional methods, which can take between one and two minutes to prepare and test each ball manually.
