Internal Combustion Rail Waist Grinding Machine

The machine is suitable for grinding works before railway laying, subway maintenance welding and gluing insulated joints construction. This work is one of the heavy workload jobs in the rail welding operation. In the past, it was mainly carried out by hand-held electric grinder or angle grinder, it has led to high labor intensity, low operation efficiency and slow working speed, poor grinding surface quality, serious environmental pollution etc.
