Hydroabrasive cutting device: battery in half in a few seconds

Waterjet cutting device

Young inventors Dan Hicken and Mitchell Fillmore from Bountiful, Utah, created a unique cutting hydroabrasive device that creates a pressure of 400 MPa. This was enough to cut the car battery in half a second . The video with the episode of cutting scored more than 111,000 views.

It may give the impression that a huge amount of water is consumed during the cutting process. In fact, the flow rate is only 4.5 l / min. The secret of such high efficiency lies in the combination of high pressure and abrasive in the form of fine granite sand, which is pumped through a nozzle with a diameter from the sewing needle.

During cutting, the nozzle moves along a certain trajectory at a specified speed. Depending on the material from which the object is made, the pressure and cutting speed are selected.
