- Nextgrid 4y agoWaterjet cutting uses water to propel a powder which acts as an abrasive, like an infinite stream of sandpaper. I don't think water by itself will achieve much.

- climb_stealth 4y agoHuh, thanks for mentioning this! I always thought it was just water with enough pressure. It looks like pressure cutting with pure water exists but it is limited to softer materials. This page [0] has a fair bit of detail on it all.

- daenz 4y agoSounds like pressure washing vs sand blasting. Only difference between the two (aside from drastically different effect) is sand blasting has an intake tube to suck sand into the water jet.
- fortran77 4y agoPeople have made DIY waterjet cutters with pressure washers and a sand feeder: https://www.youtube.com/watch?v=Lg__B6Ca3jc https://www.youtube.com/watch?v=Lg__B6Ca3jc
- nullc 4y agoWaterjeting without abrasive is a thing, it's used for soft materials like rubber... and there are some companies marking higher pressure approaches for metal (though usually with tiny amounts of abrasive rather than none at all).
- gonzo 4y agoIt’s also used in commercial food prep.
- walnutclosefarm 4y agoWater is not doing the cutting there. Water is just the carrier for garnet abrasive, which does the actual cutting. Garnet is roughly three times harder than steel, so at high pressure cuts it very effectively.
