Portable approach checks hardness efficiently
A transmissions manufacturer has adopted a portable approach to ensure that all components rescued from defective gearboxes and drive trains are hardness tested rapidly and economically.
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.
Previously, the Company transported selected parts mainly gears and shafts to an outside test house to establish if they had, for example, been softened by overheating.
This was a slow and costly process that militated against comprehensive investigation of all potentially useful components, particularly the large and heavy ones.
With the handheld tester from Indentec the Company can now carry out in situ and bench testing of all parts immediately, regardless of component weights, sizes, shapes and awkwardness of location.
Additionally, debatably valuable parts that once might have been ignored can now be included in the test programme.
Less than half the price of a conventional benchtop hardness testing machine, the Indentec instrument can be applied from any direction, including (unusually) upside down, to produce an on the spot reading and print out of the hardness of the component in any of the popular hardness scales.
VOR, which tests mostly to the Rockwell C scale, says that the compactness and easy operation encourage general use by shop floor staff, leading to more exhaustive searches for viable components.
The tester calculates hardnesses automatically to plus/minus 0.5 percent scale accuracy.
The reading appears on a built in digital display, which also shows test scale, material tested, number of tests, running average hardness, direction of test, and ultimate tensile strength.
The results are recorded by an infrared printer for logging in computer.
According to VOR, this instant availability of printed hardness confirmation is helpful in negotiations with customers and suppliers.
It also provides hardness records for components destined for stock to wait remanufacture into new transmissions or delivery as spare parts.
