Tensilsaw

October 30, 2013

Straight strips cut from non-metallic materials can be tricky.  A shear can tear the edges, and dies are expensive, and require sharpening to avoid edge damage to the strips.

Tensilsaw is designed to cut straight strips from non-metallic materials, including plastics, composites and fiber reinforced materials.  Once the strip width is set, it is repeatable indefinitely, until you choose to change it.  Cutting strips from a plaque is extremely fast and easy with the Tensilsaw, designed for use in the lab by non-machinists.  Diamond plated and toothed blades are available for use on different materials.

The straight strips prepared by the Tensilsaw can be used as is for tests such as flexural  testing, or the Tensilsaw can be used to cut blanks for insertion into templates for the Tensilkut machine, from which specimens such as tensile, compression or fatigue bars can be cut.  The Tensilsaw can also prepare the .500″ wide blanks needed for insertion into the Impactmill, which notches Charpy and Izod impact blanks in accordance with ASTM D256.  It will also cut the .75″ and 2.2″ wide blanks required for insertion into the V-Mill templates for the Iosipescu shear test notches.

The Tensilvac can also be added to the Tensilsaw to collect most of the dust and debris from cutting strips.

Tensilshear

Tensilshear is a rugged hand shear designed specifically to cut straight strips from sheets of metal.  Strips can rapidly be sheared from sheets of light foil, steel up to 1/16″ thick, or aluminum up to 1/8″ thick.  These strips can then be inserted into templates for the Tensilkut I or Tensilkut II, and cut into tensile specimens.  Other applications include preparing blanks for paint, corrosion or similar tests.

The hardened blade on the Tensilshear ensures smooth, burr-free strips.  Micrometer gauges at the back enable the user to set the strip width accurately to best suit his needs.

ASTM D638 Type IV tensile bars can be quickly and easily cut on the Tensilkut I or Tensilkut II manually operated machines.  Thinner blanks can be stacked together in order to prepare multiple specimens at one time, significantly cutting down the time required to prepare each tensile specimen.

ASTM E8 Threaded Tensile Bars

V-Mill for Iosipescu Shear Samples

October 6, 2013

V-Mill is a new machine designed specifically for preparing the V-notch in Shear Test Specimens.  The test is done on composite materials in accordance with ASTM D5379 and ASTM D7078, using the Iosipescu shear test fixture.  Tensilkut Master Templates developed specifically for these test methods ensure accurate location of the notches within the test blank, while the cutter manufactured specifically for this notch  creates perfect 90 degree notches with the required radius at the base.

Impactmill: Redesigned

October 4, 2013

The Impactmill has long been a workhorse for notching prepared .500″ wide blanks in accordance with ASTM D265 for Charpy and Izod tests.  We have recently redesigned this machine to include an easier method of loading the specimen blanks, more convenient notch depth control, and easier feeding of the specimen through the cutter.  Additional venting for the heavy duty motor which powers the notching cutter  has also been added.
