How long can the waterjet sand pipe be used?
Under normal use, when the width of the cutting seam is more than 2mm, the wear of the sand pipe is more serious, and its service life has been reached. The new sand tube should be replaced and replaced. In addition, the water beam emitted by the water knife will weaken with the increase of the distance from the jewel nozzle, so the shape of the cutting section will appear twill, and the closer to the surface of the workpiece, the more rough the surface of the workpiece is.
At present, the thickness of the workpiece that can be cut by water jet can reach 100mm, and the cross section of the workpiece is relatively smooth. In fact, the production of the cutting cross section is also related to the water pressure fluctuation of the water knife, so long as the pressure is increased and the speed of the cutting movement is reduced, the situation of the cross section can be improved effectively.
