Notched Samples: Impact and Shear Testing

September 7, 2017

Tensilkut is known for high quality, accurate machines for preparing flat and round tensile bars.  But we also build machines for notching specimens, which is one of the hardest things to accomplish.  For Impact specimens in accordance with ASTM A370 for metal bars, we offer the Impactkut, a fast, accurate and durable machine which broaches the notches with a single stroke of the 24″ long

broach tool.

ASTM D256 specimens are used for testing plastic or composite impact specimens; the Impactmill notches those specimens in one pass through the machine.

For Iosipescu Shear Test specimens in accordance with ASTM D5379 or ASTM D7078, the V-Mill notches both sides of the specimen quickly, with the notches perfectly aligned.  This machine was developed in response to customers in the aerospace industry, who were among the earliest to suffer the difficulties of preparing these notches.
