Model M-2 Metallography specimen pregrinding machine is a kind of wet type
pregrinding machine. Taking advantage of various water-resistant sand paper
with different granularity, it can be used to pregrind various metal and alloy
materials. By using this machine, manual grinding can be replaced by
mechanical grinding so as to improve specimen preparing efficiency, also the
deforming and heating traces produced during cutting can be removed
completely. This will be suitable to observe and measure the metallography
structure of specimen under microscope.
