Charpy Notch Broaching Machine

This type of machine is specifically designed for preparing notch specimens for charpy test. our machine has2 sets hydraulic system (2motors and pumps, 2 oil chamber) one is for notch making and others for lubrication system. and also our machine is able for broaching 2 sample in 1 time becouse three are2 brouches on both sodes. NSM-201B is a specific machine for notch metal specimen, which is combines machine tool design with material testting standard

FEATURES:

STEP LESS speed change, hydraulic drives , double broaching tools can work simultaneously (specific broaching tool ±aterial : W18Cr4V)
