Waterjet Cutting Opens New Doors
Mitsubishi
Those looking to expand
beyond cutting and machin-
ing only metallic products,
such as ceramics, composites,
plastic, glass and stone, find
waterjet cutting to be the
process of choice. While dis-
cussing waterjet technology
with the folks at the Mitsubishi
booth at Fabtech, we learned
about its new entry-level machine due to be introduced early in 2012. While not quite ready to be displayed at Fabtech, Mitsubishi personnel offer MetalForming readers this sneak preview.
Dubbed the MW3, Mitsubishi’s new entry-level waterjet-cutting machine should prove ideal for production environments and customers new to waterjet, we’re told. “Its solid base construction and cantilever head design make it reliable and affordable,” say company officials. The machine is provided with a Model 720 CNC control boasting easy-to-use menu and help functions to guide operators through programming and workpiece setup.
The MW3 will come standard with a high-pressure S-50 KMT pump, which pro- vides 60,000 PSI of water traveling up to Mach 2 with 1.09 gal./min. of water con- sumption through a maximum orifice size of 0.013 in. The reciprocating hydraulic
piston to ceramic water piston ratio is 20:1, pushing the water into an accu- mulator that maintains a smooth, even flow to the cutting nozzle.
(KMT launched two new intensifi- er pumps at Fabtech: its Streamline Pro2 in 60- and 125-hp models, and the NeoLineTM40i 55,000-PSI pump that features a new, low-profile cabinet to ease operator access to controls and components.)

Techni Waterjet
Techni Waterjet featured its TJ3000- X2 waterjet-cutting machine at Fabtech, along with its Quantum ESP55 electric servo pump. New for the firm is its abrasive-delivery pump and hopper system, designed to eliminate all mechanical moving parts from con- tacting the garnet. This, say company
Faster progressive die design.
Webcast “Introduction to NX Progressive Die Software”.
Progressive die design can be one of the most challenging tooling disciplines. Predicting sheet metal formability and validating tool performance with physical try-outs is costly and time-consuming. To reduce try-outs, slash lead times up to 30%, and trim tool costs you need an automated design system with integrated capabilities for formability, analysis, and motion simulation.
During our free webcast “Introduction to NX Progressive Die Software” you’ll learn how to apply the latest CAD/CAM/CAE technology from Siemens PLM Software to optimize your die design time throughout the manufacturing process.
