Description & Specification for Lab Tenders
Detailed product overview for Astra Scientific Automatic Grinding Machine — suitable for institutional purchases and international tender submissions.
Technical Specification
Complete technical data, dimensions, capacity and performance parameters for Astra Scientific Automatic Grinding Machine.
Specification:
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 cylinders ends 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 surface is 0.05 mm. and the deviation
of perpendicularity of the side with reference to the end faces is 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 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.
