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.
Simultaneously Vickers test up to twelve surfaces
No less than nineteen different specimens can be supported for hardness testing by a single fixture developed by Indentec.
The unique nose mounted indenter and dead weight, friction free load application system make this instrument eminently suitable for automatic applications.
The specimen clamp is designed to eliminate movement due to losses in the translation stage, leadscrew and component support interfaces during the test cycle.
Any losses when the 150kgf main load is applied will result in 'soft' answers, which would impair/compromise the first two or three test results.
The clamp saves test time normally spent performing dummy indentations.
A PC and controlling software are not required as the hardness testers internal computing power has been utilised to manage the test cycle automatically.
The operator can select either to test according to the ISO 642 or ASTM A255-02 International Jominy Standards.
Alternatively, using the touch screen fornt panel, it is possible to define a non standard traverse pattern to suit individual customer requirements.
Results are automatically downloaded via the RS232 port into data capture software for storage, retrieval, and analysis.
As with all Indentec products the system is UKAS accredited in line with Rockwell standards ISO 6508, ASTM E18 and quality standard ISO 17025.
The instrument is supplied with certified test blocks and indenters which are traceable to the National Physical Laboratory in London.
