Demonstration of the Tensilkut II

June 23, 2015

The Tensilkut II is used to easily prepare flat tensile, compression, flexural and other specimens from metals and non-metallics.  This machine is designed for operation in the testing lab by technicians without previous machining experience.

The starting blank is inserted into the Tensilkut Master Template, and the clamping screws are tightened as shown in this video.  The micrometer dial on the Tensilkut control head is set to its starting position, and a series of light passes are taken to cut the material from each side of the specimen.  When the correct tensile specimen dimensions are achieved, the micrometer dial will stop turning, thus preventing cutting an undersized test specimen.  After removing the completed ASTM E8 or other specimen from the master template, the tensile bar is ready for immediate testing.

ASTM D695 Compression Testing

May 13, 2015

Preparing the ASTM D695 Specimen for compression testing is a two step process.  First, the gauge section must be cut in the blank, using one of the Tensilkut Master Templates designed specifically for this purpose.

After the gauge section has been cut, the specimen is inserted into the Tensilkut Master Template which cuts the ends square and parallel at 3.13″, in accordance with ASTM D695.  Different templates are available for  Tensilkut I and Tensilkut II machines.
