Automatic Specimen Grinding Machine

STANDARDS : EN 12390-1, 12390-3, 12504-1; ASTM C 31, C39, C42, C192, C617

ParsRos Automatic Specimen 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 lenght of the any specimen must be longer than 110 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

perpendicularity of the side with reference to the end faces should be 0,5°.

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 aluminum to obtain a lighter weight and the stainless steel exterior shell assures resistance to corrosion.

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 seperately.

The cradle and the water restraint panels should be ordered seperately for 100mm and 150mm cubic specimens.

Filtration and Circulation System Water Tank is designed to save the amount of water used during the etching process in automatic grinding machines
