Product Summary



For notching prepared blanks in accordance with ASTM D256 for impact testing



Product Detail



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. For a Youtube video of the Impactmill in operation click here





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.



To prepare the blanks which the Impactmill notches, either the Tensilsaw or the Tensilkut machine can be used.



Impactmill from Tensilkut Engineering



The Impactmill is used to notch prepared .500" wide blanks in accordance with ASTM D256 for impact testing. The blanks can be cut with a properly adjusted Tensilsaw, or with the Tensilkut I, Tensilkut II, or CNC Tensilkut III. The clamp will hold multiple specimens, in accordance with the ASTM requirement that specimens be prepared with a backer bar. The Impactmill is easily operated, requiring no previous machining experience. The Impactkut for notching prepared 10mm square blanks from metals for ASTM A370 impact testing, is also available.
