Automatic Grinding Machine
Product Code : EL-RTLE-10503
Quick Answer: The Automatic Grinding Machine provides fast, automatic grinding of concrete cylinder specimen ends to obtain plane and parallel surfaces, handling three ø38 to 100 mm units or two ø150-160 mm units simultaneously (specimens must be longer than 70 mm), with a grinding time selectable from 50 to 400 seconds and an optimum grinding time of 90 to 120 seconds per end. It features an aluminum frame with a corrosion-resistant stainless steel exterior shell, integral wheels for mobility, and a safe, ergonomic, easy-to-install design, measuring 730 x 1080 x 1510 mm, weighing approximately 280 kg, and drawing 1850 w of power.
The 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 cylinder ends can be ground simultaneously with the suitable cradle and water restraint panel, and any specimen must be longer than 70 mm. According to ASTM and EN standards, the planeness accuracy of grinded surface is 0.05 mm. and the deviation of perpendicularity of the side with reference to the end faces is 0.5o.
The cradle on which specimens are fixed has automatic bidirectional radial displacement ability, and the safe and ergonomic design prevents the user's exposure to water and dust while providing easy access to the water inlet and outlet. Specimen cradles and water restraint panels can easily be installed without the need for any assembly. The equipment has selectable advance grinding time functionality by the user, from 50 to 400 seconds, and the optimum grinding time per end of all type specimens is 90 to 120 seconds.
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. The water restraint panels should be ordered separately for cubic specimens or different sized cylindrical specimens.
