This UV series machines are mainly for Charpy Impact Specimen U V notch Broaching.
GB/T 229 Metallic materials -Charpy pendulum impact test method
ASTM E23 Standard Test Methods for Notched Bar Impact Testing of Metallic Materials
ISO148-1 Metallic materials -Charpy pendulum impact test
1) It adopts hydraulic transmission to ensure the geometric accuracy of the notch of the specimen.
2) The machine adopts the principle of one broaching and forming, its processing identity is excellent, which can guarantee that the sample notch is 100% qualified.
3) All broaches are made of imported W18Cr4V materials, which have high hardness and good abrasion resistance. Each broach can be machined to more than 20000 samples.
4) It is equipped with double broaches, which can be used to process two notches at the same time: one V type and another U type( Or double V type, or double U type). No need to exchange the broach whether V type notch or U type notch, the notch processing needs only 10s.
5) Special inner lubricating device to ensure good lubricity, which can prevent from damaging broaches, and the equipment is equipped with iron chip recovery box, easy to clean.
