Tensilsaw Demo

July 28, 2017

The Tensilsaw, with the 60-66 diamond plated Tensilsaw Blade, is perfect for cutting fiber filled plaques into strips, as shown in this video.

The Tensilsaw cuts through this sheet very efficiently, creating strips which are ready to be cut into tensile bars on the Tensilkut I, Tensilkut II or CNC Tensilkut III, notched for izod impact testing in accordance with ASTM D256, or used for flexural or other tests requiring a straight strip of a precise width.  The width is controlled via precision spacers, ensuring that the width doesn’t change unless you wish to change it.

Tensilkut II

July 24, 2017

The Tensilkut II is an efficient, cost effective way to prepare tensile samples.  Recently, we cut some specimens from fiber filled composites for demonstration; the attached video shows the cutting of two ASTM D638 Type I tensile bars, from start to finish, in about 8 minutes.

This video also shows measuring of the specimen during the cutting process, which is not necessary with a properly adjusted Tensilkut machine and master template, but does demonstrate the accuracy of the system.  Tensilkut machines are designed to be operated by lab personnel without previous machining experience.  Please contact us today for further information on how we can help you with your testing program.

Tensilsaw for Fiber Reinforced Plastic Strips

July 17, 2017

New on YouTube: the video demonstration of the Tensilsaw being used to prepare strips of fiber reinforced plastic from 12″ square plaques.  The material saws quickly and easily, with minimal operator training.

After t

he strips have been prepared, they can be used for flexural testing, or any test requiring a straight strip.  Alternatively, and frequently, the Tensilsaw is used to cut blanks for insertion into the template, to be cut using the Tensilkut II or Tensilkut I into tensile bars.  A common specimen to be prepared in this manner is ASTM D638, or ASTM D695 tensile bars.  Another use for such strips would be for insertion into the V-Mill template, to be notched for Iosipescu shear testing in accordance with ASTM D7078 or ASTM D5379.

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.
