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.
