Special Master Templates

For nearly as long as Tensilkut machines have existed, people have wanted to prepare custom test specimens.  These are some of the more unusual ones:

This is a special template to cut micro tensile bars from very tiny pieces of materials.  Typically, this is the type of test specimen one might use if cutting from precious metals, or from “historic” material which has been in storage, and to which a comparison with a modern material is desired.  These are also used to prepare samples from materials which are irregularly shaped, and therefore, only a small piece can be obtained for the test.

I truly have no idea who ordered these Special Templates, or what the purpose was of having multiple reduced sections.  I only know that these are very interesting in appearance, and the story behind them must have been somewhat intriguing.  Note that these specimens have holes in them for pin loaded grips; Tensilkut Engineering can install hardened bushings for guiding the drilling of such holes.

If you need to create a custom specimen, why not submit your drawing to Tensilkut for a quotation on a system to meet your needs?

Spring in Tennessee

Spring actually arrived a couple of weeks ago in Tennessee, but we take pride in keeping the Tensilkut building looking inviting.

Guide Sleeves

Because of the process of operating the Tensilkut I and Tensilkut II, the guide sleeves eventually wear out.  We keep all sizes of guide sleeves in stock for immediate shipment.

Snow at Tensilkut

It’s snowing in Tennessee – a rare occurrence, especially this early in the season.

Snow at Tensilkut

But it looks a little like the Christmas season.  We probably won’t decorate this evergreen with tensile bars, however.

 

10-13 Tensilkut I

The 10-13 Tensilkut I is the same size and model as the original Tensilkut machine first made back in 1955.  This machine has the smallest motor of any Tensilkut machine, whether a Tensilkut I or Tensilkut II, and consequently the lowest cutting capacity.  It also, true to the Tensilkut heritage, does an excellent job of preparing tensile specimens from thin materials.  While we don’t recommend this model for cutting steel samples of more than 1/8″ thickness, and certainly not for harder materials, it does a superb job at preparing aluminum and softer materials of up to 1/4″ thickness.

10-13 Tensilkut I with 50-12 Master Template

The 10-13 Tensilkut I is a fine choice for a small testing lab, where space is at a premium, or where only a limited number of specimens are needed.  As with other Tensilkut machines, this machine will prepare specimens in a wide variety of specifications, including ASTM E8, ASTM A370, ASTM D638, or whatever you might need.  Contact us for more information and a quote, or visit our Tensilkut website for more information on this and other equipment to make your lab more productive.

Cutting Round Monel Tensile Bars

Recently, we shipped a CNC Tensilathe to a customer who was cutting, amongst other materials, Monel.  This is a very hard material to cut, but the CNC Tensilathe handled it well.  These are pictures of a shaving from the monel bar, as it was being cut; we cut it in .012″ deep passes, which would equate to approximately 10 passes for an ASTM E8 bar cut from a .750″ diameter starting piece.

Starting with an irregular bar would require more and shallower cuts, but with Tensilkut’s CNC machines, we program the specimens for your starting size and shape, and you insert the blank into the machine, select the specimen from the drop down menu on the integral computer, and walk away until the cycle is finished, and your specimen is complete.

Complex Round Test Bars

In addition to being able to turn perfect shouldered, button head and threaded tensile bars, Tensilkut’s CNC Tensilathe has been used for preparing more complicated, proprietary test specimens.  This one is a fine example:

Tapered stress test bar

This is a bar designed by a customer for a specific test of longevity of Hastelloy.  Each of the end sections on both ends is tapered, as is the gauge section.  This test specimen is beautiful in its complexity.

Ends of tapered stress test bar

Of course, because it was turned from Hastelloy, accommodations had to be made in the program; when the program would turn steel or stainless specimens perfectly, the deflection from the Hastelloy caused it to be oversized.  When we program your specimens for the CNC Tensilathe or the CNC Tensilkut III, we want to receive several samples of your actual material, so our programs will accurately prepare your test bars, regardless of its properties.  Machines which accurately prepare physical test specimens are the only things we’ve ever built, and we pride ourselves on offering the best sample preparation equipment available.

40-75 Tensilbis

The 40-75 Tensilbit is our carbide burr Tensilbit.  It is .500″ diameter, suitable for use on all Tensilkut I or Tensilkut II machines.  The 40-75 Tensilbit is suitable for cutting test specimens from fiberglass, composites, filled and similar materials; the cross cut effectively cuts the fibers in these materials, ensuring a smooth finish for the best possible test specimen.  Note, however, that Kevlar does require one finishing pass of .002″ with the 40-76 Tensilbit, to clean up the lower edge of the specimen before it’s removed from the template.
