Impactmill

June 17, 2009

The Impactmill accurately notches plastic and non-metallic materials in accordance with ASTM D256 or ISO 180.  The totally enclosed ½ HP motor rotates a precision ground, single tooth cutter at 1000 RPM.  One or more prepared .500” wide blanks are clamped in the Impactmill’s holding fixture; a rotating cutter notches the specimens as the handwheel is cranked to move the fixture through the cutter’s path.  A micrometer control is used to raise and lower the notching cutter on the Impactmill.  To check the depth of the notch, a micrometer with a knife edge is mounted on the unit.  It is used to accurately measure the critical distance between the tip of the “V” notch and the back of the izod or charpy impact bar.  As with all Tensilkut equipment, the Impactmill is designed for location in the laboratory, and can be operated by technicians with no machining experience.

Tensilmark

June 9, 2009

The Tensilmark is a compact, freestanding unit designed to scribe gauge marks on prepared flat or round specimens made of most machineable materials.  The marks are accurately produced on 1” or 2” centers, within ASTM tolerances of +.002”.  A floating steel bar contains two hardened steel scribe pins for rapid and consistent elongation marks on specimens.

Flat specimens are held in place in the Tensilmark by a positioning bar located in front of the floating steel bar.  The Tensilmark model designed for marking round specimens holds the piece to be marked in a pair of “V” blocks.

For those with custom marking requirements, the Tensilmark can be manufactured with special pins for metric measurements, or for longer samples.
