Hypertherm , a U . S . -based manufacturer of industrial cutting systems and abrasive waterjet cutting systems ( including intensifierbased pumps , abrasive recycling systems and AccuStream consumables ) introduced predictive maintenance waterjet pumps in 2018 ‘ to substantially reduce maintenance costs and disruption caused by non-planned service ’. This generation of pumps — called HyPrecision Predictive — is equipped with features such as Hypertherm ’ s Advanced Intensifier Technology .
Recently , Hypertherm announced a new name for its HyPrecision™ and Echion™ waterjet pumps . It is rebranding these intensifier-based pumps as DynaMAX™ to unify the naming of its intensifier pumps . HyPrecision pumps also get a make-over . The pumps will now have a black exterior to match the exterior of the Echion pumps .
All Hypertherm ’ s intensifier-based pumps feature more consistent hydraulic and cutting pressure from a closed-loop proportional pressure control ; advanced intensifier monitoring ; a fluid management system and low maintenance costs for intensifier-style waterjet pumps .
It also launched the Hypertherm Connection Hub , a new virtual event platform , to provide access to live product demonstrations , learning opportunities and conversations with Hypertherm plasma , waterjet , and software experts . In April 2019 , Hypertherm completed the acquisition of OMAX , a leading supplier of integrated waterjet cutting systems based in the U . S .
Intermac ( part of the Biesse Group ) offers its Primus range of waterjet cutting systems . The fiveaxis cutting head is fitted with the patented Intermac infinite rotating C-axis system for making tilted cuts (+/ -60 °) on complex profiles , with no limits . This system , says Intermac , eliminates the errors due to rotating axis reverse clearance in traditional
methods , and also guarantees a constant supply of abrasive material .
Jet Edge , Inc . manufactures complete systems for precision water jet cutting , mobile waterjet cutting and UHP cleaning and surface preparation applications , as well as accessories . Models include the Edge X-3 mid-rail gantry waterjet , the Edge X-5 five-axis waterjet and the Edge X-HR high-rail gantry waterjet . It also offers a wide range of waterjet pumps , including hydraulic intensifier pumps and direct-drive pumps .
“ Our Edge X-5 features five-axis waterjet cutting that is capable of bevel cutting to 60 °. Complex 3D parts , including impellers and gears , can be cut in the hardest materials with a taper-free finish . Controlled with the fully-networkable Aquavision DI , the system is optimised with multiple heads , nesting software , laser surface mapping and lights-out cutting . It also comes with a Jet Edge UHP Pump ,” said the manufacturer .
