Our client, leader in its sector, is a producer and provider of electricity in France and Europe for companies, public communities and individuals.
Tested products: metal test bars
Metal test bars intended to characterize materials in fatigue according to their surface condition.

Polishing metal test bars in a simpler and faster manner.
Our client wishes to conduct low fatigue cycle tests at very low deformation on metal test bars. For this type of test, the influence of the surface condition of the metal test bars is particularly important; it must be known or controlled and repeatable. Our client is seeking a polishing mechanism in order to standardize the surface condition of the test bars and facilitate their realization. Our engineering team offers a polishing machine which is automated but also offers the possibility to operate in a manual way.
Solution and results
LF Technologies designed an automatic polishing machine for test metal bars by an abrasive bar, simple of use thanks to its operation panel and its digital control by computer, from which the operator can create his own test programmes.
In order to meet the client's requirements, this bench includes, in its upper part, two work stations, one is automated and the other one is manual.
The automatic work station consists of a spindle which carries the test bar and can move in a horizontal plane, and a second spindle which carries the abrasive and enables polishing the test metal bar, thanks to a programmed defined by the operator. The spindle which carries the test bar rotates around a horizontal axis to come in contact with the abrasive bar.
The manual work station, on its side, is equipped with a chuck, a tailstock and a hand-rest which allow handmade polishing.
This polishing machine enables our client to enhance significantly its productivity thanks to the automation of the polishing function on the metal test bars, providing this way a better profitability. Thanks to the polishing machine, the surface condition of the metal test bars complies with the standards that are required to conduct low fatigue cycle tests.
