Tensile specimen blanking tools

All delivered punching tools are customised to the requirements of the customers needs. All common specimen shapes are available according the different standards ISO / ISO6892, ASTM, / JIS / GHOST …

If a tensile specimen grinding machine PSM 2000 should be used the parallel length
between the heads (the fillet) should have a minimum length of 60 mm to the radius

In standard (also when damaged zone from blanking will not be removed) the specimens should be blanked with oversized specimen width (b). Later on you will discover that it is a must to remove this. But when the blanking tool does have a layout for indicated dimension in width you don’t have enough width to remove this damaged area – you will be out of indicated width of the standard.

For us it is standard to customise the tools to your needs – also if you need (in the same tool / additional tool) additional circular or square blank for hardness test or zinc coating test
