Turning Round Tensile Bars

September 29, 2017

Turning round tensile test bars has always been a difficult and tedious process.  A full charge machinist can turn a test specimen using a lathe, but it will take some time, and, unless the machinist is fastidious, it may not be within the tolerances required by the specification.  Additionally, since machinists will often turn bars using only the largest possible passes, the bar will likely need hand finishing to remove distortion caused by the turning process.

Tensilkut has two machines designed to allow you to turn round tensile bars in accordance with ASTM E8, ASTM A370, JIS, DIN and ISO specifications in the lab.  Technicians without previous machining experience can learn to run these machines in short order; as with our other machines, these machines are supplied with a self-instruction manual, so it can be used by different operators as time goes on.

The Tensilathe/505 is our semi-automatic tracing lathe.  It operates from a Master Template, which controls the shape and dimensions of the specimen.  The operator needs only to dial in each cut to prepare a perfect tensile bar.

The CNC Tensilathe is the automated round test specimen preparation system.  This machine runs on a Windows-based microcomputer; specimen preparation is accomplished with a point and click software system.  After setting up the specimen, the operator is free to complete other tasks while the sample is turned automatically.

Tensilkut: Tensile Sample Preparation Gold Standard

September 5, 2017

Tensilkut has the capacity to accurately machine tensile specimens from ferrous and non-ferrous metals and non-metallics from .002″ thickness up to .250″ or more, depending upon the model of the machine and the hardness of the material.  The Tensilkut series is fast; test specimen preparation can be completed in as little as 3 minutes, depending upon the material and its thickness.  The machined edges are so finely finished that no hand finishing is required.  The capacity to satisfactorily machine such light gauges as .002″ thick allows testing of many materials for which specimen preparation would otherwise be significantly more difficult.

Some of the bars cut on Tensilkut machines include ASTM D638 Type I tensile bars, ASTM D412 Die C tensile bars, ASTM D1855 Type L Tensile-Impact specimens, ASTM D256 Impact specimens, and ASTM D5379 Shear Test Specimens.

Tensilkut Catalog, Circa 1955

August 9, 2017

In this day of instant electronic communication, it’s hard to believe that 60+ years ago, not only was everything mailed, but Tensilkut’s catalog, when it arrived in the mailbox, contained a tensile test bar which had been cut on the Tensilkut.

The 1955 Tensilkut catalog included a drawing of the only tensile bar we made at the time, along with an actual specimen!

I don’t imagine the founder of Tensilkut ever imagined a time when we could not only send information to customers nearly instantly, but also a time when we’d be able to make videos available for people to see whenever they wished.  Despite sea changes in communication, the need for his original machine remains very real – and at least one of the machines made in his first couple of years remains in service today.

A Blast From The Past

August 7, 2017

Recently, while browsing the Tensilkut Ancient History file, our catalog from October 1, 1956 appeared.  It was a simple affair, with a heavy sheet as front and back cover, and a single sheet describing the entire Tensilkut line, consisting of the Tensilkut (one model only) and its template.  The cover was adorned with a four-color photograph, glossy, of course (at a time when color photography was less common and rather expensive).

How far we have progressed today, to our line containing numerous models of the Tensilkut I, Tensilkut II and CNC Tensilkut III for preparing flat tensile specimens, along with the Tensilgrind for high hardness flat samples, and machines for round and notched test specimen preparation!
