FOCUS ON WATERJET CUTTING

The newly launched FiveX Ultra from WJS . and EDM cutting and brings waterjet cutting into micro part processing . To enable such levels of precision you need two things : ( 1 ) a cutting head and cutting process for FAWJ cutting and ( 2 ) a machine built for extreme accuracy . The NCM 10 Micro is Water Jet Sweden ’ s offering which it has designed to meet both these requirements .
WJS has showcased an Augmented Reality , 3D version of one of its advanced waterjet machines , the FiveX , so that visitors could get closer to the operational cutter and look at it in 1:1 , 1:4 or 1:10 scale , and then take it home with them on their smartphone or tablet . The company ’ s entry-level waterjet cutting systems include the T-model and H-model . Its Grand range is a heavy-duty waterjet cutting system with large tables sizes to manage large and odd-sized materials .
TECHNI Waterjet manufactures waterjet cutting solutions for the metals , composites , glass and stone industries . Now part of the GMM Group , it controls the entire waterjet process in-house , with its own developed servo-driven pump and five-axis cutting head and holds several patents on its technologies . Its Electric Servo Pump is designed to be efficient and quiet .
“ Our new Intec-G2 ® waterjet machine cuts parts up to 12 ” thick in most materials . Simple to use , its versatile cutting allows users to cut multiple material types on the same bed without having to change tooling ,” it explained . “ Our Quantum NXT™ Series pump incorporates technology from the NASA space shuttle programme , making it 60 % more efficient than standard hydraulic intensifiers .”
Uhde High Pressure Technologies GmbH has been designing and manufacturing ultrahigh-pressure pumps for pressures of up to 14,000 bar for industrial use for almost half a century . Its high-pressure pumps - the core element of the waterjet cutting system - with stepless working pressures of up to 6,000 bar are implemented in many relevant industrial sectors , from the food industry to aerospace . Water Jet Sweden , based in Ronneby ( southern Sweden ) is a well-known waterjet cutting specialist with over 100 different waterjet cutters from entry-level 2D machines and micro processing to large machines for large and odd sizes of material , with its fiveyear performance warranty . At EuroBLECH 2022 this October in Germany , and FABTECH this November in the USA , WJS launched its new five-axis machine concept : FiveX Ultra ( 4200 bar technology at 60,000PSI ).
“ FiveX Ultra is a compact and lean version of the large-scale 3D cutting machine model , FiveX . It is designed to manage a wide range of cutting assignments from 2D up to full 3D , any material . FiveX Ultra has a new design platform to make it slim , light and extremely stable ( as WJS known standard ) with improved accessibility and visibility ,” commented Lennart Svensson , CEO and President of Water Jet Sweden .
Its Alphajet , which it dubs ‘ the next generation of taper angle control and perpendicular waterjet cutting ’ is mechatronics based on compact design with a fixed TCP point .
“ Extraordinary cutting result can be achieved with carefully selected machine elements and small precise movements at an angular accuracy within ± 0.05mm ,” it told ISMR . “ You can fit up to four Alphajets on the same machine , thereby quadrupling the cutting capacity .”
The Fine Abrasive Waterjet ( FAWJ ) cutting process bridges the gap between micro laser
EDRIVE™ PRO is an all-electric servo intensifier pump able to generate pressure of up to 6000 bar ( 87KPSI ).
Italian manufacturer , Waterjet Corporation Srl , offers a range of electric servo intensifier pumps ( such as EDRIVE , EDRIVE PRO and SERVODRIVE ). Its EDGE 5 cutting system features integrated ITC . Its machines include cantilever and bridge designs and five-axis flying bridge technology ( Edge 5 ) which delivers significant productivity improvements . The company also offers combination plasma and waterjet machines , as well as waterjet surface texturing technology .
Wazer is now offering what it calls ‘ the first desktop waterjet ’ at 864mm x 635mm x 534mm . The cutting area is 305mm x 460mm . n
