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.
Projecting an image of the indentation onto a monitor for electronic measurement, the system eliminates the human judgements that can lead to reading errors and delays with conventional Vickers testers.
Repeatable accuracy in hardness measurement is crucially important for the Leeds based high volume specialist, which can produce over 200 million grease fittings a year, 90 per cent for export.
Ranging in size from 7mm to 18mm hexagon, the nipple bodies are case hardened before assembly.
The depth and hardness of the case must be established within close limits to ensure that the nipple can be peened over to retain the ball and spring, and that the assembled nipple is hard enough to be used for self forming.
The Indentec machine is operated alongside conventional Rockwell and Vickers testers in a batch inspection process following heat treatment of the nipples in a new carbonitriding line.
As well as helping speed up an intensive testing operation, the system produces related test data automatically, identifying specimens by type, batch, furnace, etc as tests are carried out.
Kingfisher says that the availability of projected images of indentations has also helped in training and familiarising operators.
Other features available in the machine include preprogramme test sequences and password secured access to prevent unauthorised use.
