hi Marcin ,
Just to fwd you my post ( from OSE workshops facebook page) , it might be interesting for CNC Torch Team future plans:
recent video "Waterjet cutter built with a cheap pressure washer " https://www.youtube.com/watch?v=Lg__B6Ca3jc
, by famous applied science mr http://benkrasnow.blogspot.nl
I see you have started collecting info for water jet : http://opensourceecology.org/wiki/Water_Jet_Cutter
Best, Branko
Notes
- 1/16" aluminum, 3200 PSI - 2 IPM cut rate
- 1 IPM for 1/8" aluminum.
- 3/8" hard wood !
Cutting Cost of Industry Standards
- As low as $20/hr for 30 hp 0.01 orifice [1].
Cutting Cost of Industry Standards
- As low as $20/hr for 30 hp 0.01 orefice. Cut rate - 7 ipm for 1/2" mild steel with 30 hp, total operating cost $12/hr. 2 largest costs are 1/2 garnet, 1/2 pump/head parts. [2]. Lowest cost is 15 hp at $11/hr.
- With 32 feet of cut per hour - this is decent for 1/2" steel. Can be a main production tool.
BOM
- [2] 10000 PSI hydraulic cylinder - $300 - [3]
- Garnet - 50c/lb [4]. Can be recycled 5x. Usage - about 1 lb/min. [5]
- There are abrasives harder than garnet (shorten mixing tube life) or softer (don't cut as fast)
- 15 hp pump - [6]
Literature Review
- Indian Waterjet with DIY nozzle At 2000 psi - [7]
Low Pressure Examples
- Water - 8000 psi?
- 17,000 psi - [8]
