Notch
Broaching Machine
Technical
Specifications
When
the casting/research engineer is put with a tight tolerance in
properties. It is necessary to test the accurate specimen. Notches
are especially critical in determining the toughness for fracture.
Close tolerance and fine surface finish in 'V' and 'U' notches to
give correct value during charpy or izod test.
SGS-10
series-broaching
machine can give significantly faster and accurate finishing to the
specimen. The machine will broach a notch in 10mm specimen to the
Indian/International Standards.
