Composite Tensile Test Sample Preparation

August 2, 2017

Recently, a customer sent us some composite strips to be cut into ASTM D638 Type I tensile samples.  We used the Tensilkut II, and the process was very fast and easy.

Tensilkut machines are sized for location in your testing laboratory, to be used by technicians without machining experience.  The Tensilkut II is a floor model, manually operated machine; table model Tensilkut I machines are also available for labs with less space available.  Visit our website at www.tensilkut.com or fill out the contact form below for more information on how Tensilkut can make your tensile specimen preparation easier!

Tensilkut, New and Improved

July 31, 2017

The new Tensilkut website is live; you’ll find information about all of our machines, along with more photos and links to our YouTube channel.

Need to make flat tensile bars? No problem! Round bars? Easy.  Flexural, impact, fatigue…it’s all here, waiting for you to visit.

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.

Tensilshear

May 23, 2015

The Tensilshear is an easy way to cut strips from small sheets of metal, including aluminum, brass, steel, and even harder materials.

A pair of micrometer adjustments on the back move the stop to enable you to simply push your sheet of up to 10″ wide metal under the blade until it reaches the stop, make sure it’s firmly in place, and cut off a strip.  The process can be repeated for as many strips as you need. It is a compact, manually operated unit, requiring neither electrical nor air hookup to operate.

The Tensilshear will shear strips from 1/8″ (3mm) thick aluminum or materials of similar hardness, and up to 2mm thick steel.  The hardened, precision ground blades are adjustable to eliminate virtually all edge burring problems.  The video below shows the Tensilshear being used to shear strips from 2mm thick hardened steel.

CNC Tensilkut III Video

September 1, 2010

Because the recent video of the CNC Tensilkut III showed very little of the motion, here is a video in which the cutting head is moving along its X axis.  Note that no cutting is occurring in this clip.  This is a Quicktime video; please download Quicktime if you can’t view it.

Operation of the CNC Tensilkut III

August 25, 2010

While there are plenty of photos of the CNC Tensilkut III, this is the first time we’ve posted video of the operation of the machine. You will have to look closely, because these samples are lined up front to back on the table, so the cutting head is moving only a minor amount on a left/right or up/down basis, and the table is moving forward and backward for cutting the length of the specimen. When the camera pans to the view of the computer screen, the red shapes indicate the uncut specimens, while the blue lines display the sample which has already been prepared.

Because the door cannot be opened while the cutting operation is in progress, we can’t give a closer view of the operation of this machine.

Tensilkut II Demonstration

August 24, 2010

To aid you in picturing the operation of the Tensilkut II, here’s a video demonstration of the cutting of a piece of 1/8″ thick aluminum from start to finish.  The footage was taken from very close range, so there are no views of the entire machine.
