TRIMMING/CUT-OFF MACHINE FOR CORES

Suitable to cut and trim cores to be prepared for compression tests,
where the flatness of both surfaces is a basic condition to obtain
correct results.
The equipment is made of stainless steel and aluminum and it is
supplied complete with diamond blade diameter 180 mm.
For this purpose it must be used the drill mod. C377-10 (enclosed
into micro-coring equipment) and the water tank with foot pump
mod. C377-01.

The maximum values expected for compression tests on micro-cores
are usually lower than 60 kN. Portable compression machine mod.
C094 (see p. 323), or a cement compression tester (see p. 422) may
be conveniently used.
Trimming of cores may be even obtained with the grinding machine
mod. C298 + device mod. C300-08 (see p. 65)
