TENSILKUT MASTER TEMPLATES

Because of the wide variety of specifications in use worldwide for testing of different materials, the Tensilkut machine does not include any standard templates. All standard specifications available for the Tensilkut machine are listed below, and can be ordered with the Tensilkut machine, or at a later date.

template_use To prepare a test specimen, a rough sheared or sawn strip which is the overall width of the finished specimen is inserted into the template between the upper and lower guide bars, and is not removed from the template until both sides of the specimen are completely machined. This reduces errors caused by reversing samples, as required by conventional milling. Where the finished specimen is too small to be held securely in a conventional two-sided template, a one-sided template is used. A sample which requires machining along its entire length is also prepared with a one-sided template. As with the more commonly used two-sided templates, any tapers are accurately blended into the template bars, eliminating the need for costly hand finishing.

To insure proper dimensions for your tensile specimens, genuine Tensilbits manufactured by Tensilkut Engineering should be used.

SPECIAL MASTER TEMPLATES

Should the standard master templates we have available not suit your exact requirements, special master templates can be designed to meet almost any testing specification, including ISO, JIS, DIN, BS and EN standards.

Test specimens can be prepared from strips varying in length from 2” to 24”, and width from ¼” to 6”. Gauge sections of the templates can be designed with or without blended tapers. A template can include drill bushings for precision alignment of holding pin holes for elevated temperature testing or for use with certain grips. Custom shapes have been designed for longitudinal testing of curved tube sections, while others have been built to machine specimens from welded sections.

Should your testing program require special dimensions, or if your samples include one or more of the unusual conditions listed above, please forward a sketch of the completed specimen, including tolerances and desired taper, to our Engineering Department for a quotation. A basic sketch for tensile specimens, indicating the required dimensions, are shown below. This can be copied, and used to create a sketch of the sample for quotation, if desired.
