In processing the inner-hole cercumferencial slots on the heat-exchanger on the tube-plate (steam drum), we often adopt the mechanical inner-hole slotting tools (spiral & eccentric structure). The hydro-slotting machine is a new slotting tool developed recently in the country. Compared with the mechanical ones, the machine is new and ingenious in design, rational and compact in structure, convenient in operation, stable in running, and wide range for processing. The hydro-slotting machine is an ideal inner-hole slotting equipment.
