  • The UTC-1040 Automatic Grinding Machine provides fast grinding of cylinder specimen ends to obtain plane and parallel surfaces according to EN and ASTM standards.
  • Three units of Ø38 to 100 mm or two units of Ø150-160 mm concrete cylinders ends and three units of 100 mm or one unit of 150 mm concrete cubes faces can be ground simultaneously with the suitable cradle and water restraint panel.
  • The length of the any specimen must be longer than 70 mm.
  • According to ASTM and EN standards, the planeness accuracy of grinded surfaces of concrete compression test specimens should be 0.05 mm. and also the deviation of perpendicular of the side with reference to the end faces should be 0,5O.
  • The equipment has selectable advance grinding time functionality by user from 50 to 400 seconds.
  • Optimum grinding time per end of all type specimens is 90 to 120 seconds.
  • The cradle which specimens are fixed on has automatic bidirectional radial displacement ability.
  • The safe and ergonomic design prevents the user to exposure to water and dust and provides easy access to the water inlet and outlet.
  • Specimen cradles and water restraint panels can easily be installed without the need for any assembly.
  • Mobility of the machine is achieved with the help of the integral wheels, and all components of the system can be safely accessed for easy maintenance.
  • The frame is manufactured from aluminium to obtain a lighter weight and the stainless-steel exterior shell assures resistance to corrosion.
  • UTC-1044 Water Restraint Panel Set for Cylinder consist of panels for Ø150 mm, Ø100 mm and Ø50 mm specimens. For different sized cylindrical specimens, the water restraint panel should be ordered separately.
  • The cradle and the water restraint panels should be ordered separately for 100mm and 150mm cubic specimens.

The Automatic Grinding Machine is supplied complete with:

  • Grinding Wheel for concrete specimens
  • Cradle for Ø:38mm to 100 mm cylindrical specimens
  • Cradle for Ø:150mm to 160 mm cylindrical specimens (Connected to the machine)
  • Water restraint panel set (Consist of panels for Ø150, Ø100 and Ø50 mm specimens)
