Notching device VRE for creating U and V notches


The VRE device is intended for the creation of V and U notches in samples intended for notch toughness tests according to the standards EN ISO 148-1, ASTM E23, GOST 9454, EN ISO 179. The device was designed so that in conjunction with optical inspection of samples OPTOLab 55 II forms a comprehensive workplace that provides 100% of the sample for notched toughness.



Key features of the VRE 20 system series

  • Robust and very rigid stand construction with high stability when notching
  • Notch formation in accordance with EN ISO 148-1, GOST 9457-78, ASTM E 23 standards
  • Possibility to make two different notches at once.
  • Easy blade change for V2, U2, U3, U5 and subsequent adjustment
  • Very high notch milling speed with automatic cycle
  • Continuous speed control can be used to mill a V or U groove on the machine into any material not exceeding the hardness of 40HRC.
  • Thanks to an ingenious system, the milled chips are caught in the lower part of the machine, where they can be easily and safely removed.
  • Centrally located controls for easy machine operation.
  • VRE system with protective safety cover, corresponding to EC directives on machinery working in accordance with new safety functions according to EN ISO 13850-SIL 1 / PL.
  • Integration into the X RUNNER robotic system.
