Transverse slotting machines for plain and corrugated PVC, PE, etc. pipes (for filtering water from wells and drainage or consolidating the soil) It is possible to open 1 or more parallel slots; variable dimensions can be made if needed. A wide variety of diamond blade or special steel blade types can be used. This machine, which we developed for drilling holes and slots in drainage pipes, can open both holes and slots at desired angles and intervals. Our machine is designed for corrugated and plain pipes. Our machine, which can open slots and holes for pipe diameters from 120mm to 500mm, can adjust hole or slot intervals with 1mm precision thanks to its encoder.
