Tensilkut Tensile Sample Preparation Equipment
A test specimen is the most important component of tensile testing for it determines the actual physical properties of the material being tested. The specimen must conform to exact physical dimensions and must be free of induced cold working or heat distortion. Qualified laboratory personnel and accurately calibrated tensile machines are important, but the ultimate test results are based on the quality and accuracy of the test specimen.
A highly skilled machinist, a precision milling machine and considerable hand finishing can achieve the required configurations of the test specimen. However, the slow milling cutter speeds create heavy chip loads and can induce severe internal distortion to the machined edges. The amount of induced cold working or heat distortion cannot be determined by visual or heat distortion cannot be determined by visual inspection, hence test results often produce erratic and inaccurate tensile properties.
Specimens of light gauge sheet must be blanked, sheared or die cut to the required tensile configuration. The basic principle of shearing causes severe deformation and distortion to the critical specimen edges and creates even greater variations and errors in the physical properties.
The ideal tensile specimen should duplicate the pure basic metal or plastic being tested with a total absence of tool marks, incipent cracks, induced stresses, internal deformation or heat distortion. Our range of TensilkuT machines achieve these ideal requirements and produce an almost perfect test specimen.
The Tensilkut II is an updated version of the original Tensilkut machine, developed in response to our customers' requests for an enhanced, yet still manually operated, economical way to prepare tensile bars and other samples. The Tensilkut II is an enclosed machine which includes integral misting, chip removal and motor speed regulation units. The chip shield around the control head protects the area around the unit from debris, while the sound deadening package absorbs much of the noise of the unit. A series of power switches located on the front of the panel enables the operator to easily access those accessories desired, while the emergency stop switch located on the machine cuts power to all systems simultaneously. For added safety, the Tensilkut II is equipped with a foot-control ("dead-man's") switch; the Tensilbit will not rotate unless the operator depresses it. As with the Tensilkut I, the Tensilkut II is accurate to within +.0005" when preparing specimens with a Tensilkut master template and Tensilbit.

The CNC Tensilathe is a new, fully automatic lathe developed specifically for turning round test specimens from most metals and non-metallics. The CNC Tensilathe employs a microcomputer which is programmable to prepare a wide variety of specimens from approximately 1/4" overall diameter to in excess of 2" overall diameter. The Pentium computer with integral hard drive includes a color monitor, keyboard and mouse.
This new lathe features a Windows based software featuring pull down menus for easy operation; neither machining nor CNC tool experience are required for the user to quickly learn to turn his own bars. Optional software will allow specimen contours to be imported from most CAD drawing programs; most users prefer to allow us to program their systems. This lathe uses a standard 3-jaw chuck; a 4-jaw chuck is available for gripping irregular pieces. The unit contains a Micro-Drop coolant system; a chip shield inhibits flying chips and reduces the noise of the lathe. An emergency stop switch is located on the front of the unit, as are all power switches.

Blanking ( Punching) Presses with Specimen Grinding System
Specimen Blanking Presses in C-Frame & O-Frame Designs for punching metallic specimens out of sheet metals with thickness up to 8mm. Also a High precision Specimen Grinding System is available.
The Tensilkut I was designed for the specific purpose of preparing flat metal or non-metallic test specimens. The compact size of the equipment permits it to be conveniently located in the laboratory. Small table top units or larger floor mounted models are available to accomodate any space and/or work volume requirements. The specimens are accurate to within +.0005" when prepared on the Tensilkut machine with a Tensilbit and a standard or special master template. Optional mist coolant and vacuum systems are available for the Tensilkut I.

Tensilkut master templates are available for flat test specimens to ASTM, ASM, AISI, BS, DIN, or any other international testing standard. These moderately priced templates have guaranteed contour accuracies within ASTM tolerances and all templates are interchangeable. A standard tensile specimen can be machined, and with no change in the TensilkuT controls, a subminiature specimen can be accurately prepared.
The Tensilgrind is a precision contour grinding machine developed for the preparation of foil and sheet test specimens from high hardness metals and tough alloys. Tensilgrind employs the basic principle of the Tensilkut, wherein a precision master template is manually guided across the table surface with the removal of metal being accomplished in a series of light grinding passes.
The TENSILATHE/505 is a precision contour grinding machine developed for the preparation of foil and sheet test specimens from high hardness metals and tough alloys. TENSILATHE/505 employs the basic principle of the Tensilkut, wherein a precision master template is manually guided across the table surface with the removal of metal being accomplished in a series of light grinding passes.
The Tensilsaw, powered by a high speed motor, is used to saw straight strips from glass laminates, composites or hard plastics. The thin diamond blade cuts the material for insertion into the Tensilkut template, or for flexural or other tests without heating or burning the strip edges. Strip widths of 1/4" to 1" can be accomplished with the Tensilsaw. A plexiglass guard above the blade acts as a chip shield.
Gauge Marks are accurately scribed on flat or round tensile specimens within ASTM tolerances of ±.002 inches. A floating steel bar contains two hardened steel scribe pins for rapid and consistent elongation marks on sheet specimens by unskilled technicians.
