Anyone with GPO-3 cutting experience!!


Mar 17, 2023
Got a job that sent me some GPO-3 to cut on my OMAX 120X water jet, looking to get advice on cutting parameters. It’s 1/4” thick medium hardness and a fiberglass poly resin mixture.
Hi there

I would go for the fiberglass setting and also select low pressure piercing and brittle. A pull to open setup would also help you out. If you do start to have issues then try reducing the event and relay timings. I would start by reducing the figure in. The high pressure collom, time to clear abrasive from nozzle when finished cutting. By reducing this it would allow more abrasive to stay in the line. This will help when piercing.
