The Plasser GWM-series grinding machines are rail surface, and corrugation grinding machines. Compared to conventional rotary grinding machines, the unique, patented Plasser grinding system is the only system available which offers a spark-free operation utilizing a water supply for lubrication of the grinding stones.
This system is not subject to fire hazards caused by rotary action grinding machines. Also, utilizing water during the grinding operation eliminates dust, which is an important factor in highly populated areas. Additionally, there is no need for operators to wear respirators or masks.
