Hard Metals - NETZSCH Grinding Dispersing

The s-Jet ® System (patent pending) is a new innovation in a line of consistent developments being made in the area of air jet milling. Final finenesses in the submicron range (example: d 50 0.2 µm) can now be achieved with fluidized bed jet mills. As opposed to conventional dry grinding processes with fluidized bed jet mills, the s-Jet ® System uses superheated steam as its milling gas.

Grinding the Hard Stuff - SME

Aug 01, 2007  This type of dressing requires an acoustic sensor that can precisely find the wheel’s edge with an accuracy of 0.000020–0.000040″ [0.0005–0.001 mm]. To grind hard materials, such as ceramics or carbide, it’s essential to have a stiff machine. This allows the use of “hard” wheels and precise truing and dressing.
