The Testing Times

I often get asked “Why do your large Brinell hardness testers not have a clamp option” The answer begins with understanding why old technology Brinell testers had and required a clamp feature. They were dead weight machines i.e. the load (in the case of regular Brinell 3000kg) was applied using actual physical weights hanging inside the machine. If a work piece or component was not clamped it could move as the weight was applied thus resulting in an indentation in the metal which could be less than the true size due to the movement. So A clamp was used to pre clamp the work piece or component thus stopping it from moving as the load was applied ensuring a true sized indentation. However a modern closed loop Brinell tester like the Tinius Olsen models FH-009, FH-008, FH-012 do not use dead weights, this means clamping of the work piece is not required. This is because the closed loop system sampling and applying the 3000kg force ensures, very accurately, that the tester keeps

Tinius Olsen’s New model FH-6 Micro Vickers, Vickers and Micro Brinell hardness testing capability. It’s an automatic Vickers hardness tester using the turret technology to hold up to two different indenters and four objectives which automatically selected and utilized when test is started. This technology can help your business make money by increasing the efficiency of your Vickers tests. By using automation it cuts typical testing time in half, more for large pattern tests. And if the pattern tests per sample need to change, for example when testing around weld sites, the time saving is huge. Simply take the stored existing pattern, use it as a template and drag the intended indent points using the mouse or touch screen as required. This tester does not save you money, it makes you money. FH-6 Material testing machine is capable of performing physical strength test in hardness on raw materials such as metal, plastics, large parts and small precision parts, it is a very
