Product Overview
  • Rockwell hardness meter for testing line tank hardness with surface preparation.

    TWIN TDM is a Rockwell hardness meter with test loads ranging from 15 to 187.5 KgF. (N 147 - 1839) but also available with loads of 750 KgF. Complies with ISO-EN and ASTM standards for Rockwell testing, which has been designed for line hardness testing of thin-walled tanks with length from 180 to 2,000 mm. and diameters between 80 and 220 mm.

    The line in question consists of two durometers with two systems of surface preparation by means of lamellar grinding wheels, with pressure increases on the wheels through absorption of current which varies according to slats consumption.

    The surface preparation systems and the two durometers are mounted on two parallel lines, so that the tank may be loaded and unloaded in the same position by means of master controller.

    The two lines are connected by the translation system / tank rotation system in order to automatically perform hardness control on two points at 180° - or 6 tests in different spots may be programmed from the control panel in order not only to perform a more accurate hardness testing, but also to comply with different regulations according to the country.

    Obtainable productivity amounts to 40 seconds per tank with two opposed tests.
