Used to grind and polish rock and concrete specimens, natural stones, ceramic materials, etc. Proposed in two versions:
All the other specifications are the same.
The cube and cylinder specimens can be easily locked on the table and the grinding head, 330 mm dia., can be radially moved either manually or automatically in both directions. This means that the only manual operation required is the lowering of the grinding head by the top hand wheel. The machine is supplied complete with safety chip guard that, when removed, automatically stops the machine. The standard configuration also includes the coolant tank, motor pump and one set of abrasive sectors. Diamond grinding sectors are available on request (see accessories). The machine is supplied complete with clamping element for 100, 150 and 200 mm cubes. Clamping devices for cylinders and the device for dry grinding operations are also available on request (see accessories). The Core face preparation jig can be easily fitted by the clamping element supplied with the machine.

Description The West Cerchar Abrasivity Index Tester is designed to determine the rock abrasivity index (CAI) for the purpose of quantifying the classification of rock materials abrasivity. This type of test is especially valuable in the mining industries, underground construction […]
This universal saw, completed with the suitable accessories, can be used to cut concrete and rock cores, and irregular rock samples in order to obtain geometrically defined samples. It can be fit with 300 to 450 mm dia. blades.
This apparatus was originally developed at Imperial College, London, by Professor E. Hoek. It is a simple and practical method of determining the strength and slope stability of rock, both in the field and in the laboratory.
The apparatus consists of a load frame 60 kN cap. with a hydraulic loading ram actuated by a hand pump. The frame is adjustable for testing samples up to 102 mm dia.
NG-CoreTrim is used to obtain rock samples perfectly machined (cube, prisms, etc) from irregular rock or core pieces. It is supplied complete with a proper vice to hold irregular pieces firmly in place up to 7x14
This machine is specifically used in the laboratory for cutting core samples from hard materials such as rock and concrete.
