CNC Tensilkut III For Multiple Samples

October 3, 2017

Often, our customers are interested in the CNC Tensilkut III to gain the ability to clamp multiple blanks into the machine, start it and have the freedom to do other things while the machine cuts specimens unattended.  To that end, we typically set up the CNC Tensilkut III with multiple work stations, so several specimens (typically between 4 and 6, depending upon the size) can be cut at once.  This is a typical table, configured to clamp 6 strips for the preparation of ASTM E8 samples.

Once the strips are clamped to the table, the specimens are chosen on the included computer, using our Windows-based point and click system; the machine then runs through its cycle without any operator interaction.  When it’s finished, the CNC Tensilkut III shuts down, indicating that it’s safe to open the front door and remove the specimens, at which point it can be reloaded for another set of specimens. When located in the testing lab, a Tensilkut machine lets you cut your tensile bars as you need them, on your schedule.


Cutting Specimens from Plaques

March 31, 2015

Some customers wish to cut specimens from plaques, using the CNC Tensilkut III, without first cutting the pieces into strips. This unit can be designed to do just that.

The machine is programmed to cut the specimens you need in the layout you desire. All clamps are custom made, and, as shown in this photograph, this plaque will be cut into ASTM D638 Type I specimens, cutting the entire length of each bar.

Often, a plaque which is to be cut into all tensile bars is sawn into strips using the Tensilsaw before the pieces are clamped into the machine. More commonly, when a customer wishes to cut specimens from a plaque, he wants several types of specimens, including tensile, flexural and impact blanks.

Although this can be done for thin plaques of metal, it is not recommended, as the cutting time is significantly longer, and the cutter wear will be much greater. Using the Tensilshear to cut metal strips to be clamped in the CNC Tensilkut III is much more efficient.

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.
