  • USA1 Coherent jet nozzles for grinding

    A nozzle assembly and method is configured to apply coherent jets of coolant in a tangential direction to the grinding wheel in a grinding process, at a desired temperature, pressure and flowrate, to minimize thermal damage in the part being ground Embodiments of the present invention may be useful when grinding thermally sensitive materials such as gas turbineThis trend is related to the grinding nozzles jet being submerged in the circulating bed At higher pressures, ie, in the 4, 5 and 6 barg cases, there is some disparity in the kinetic energy of the particle system, accompanied by fluctuations, as the mass loading is increased The difference in the trends between the low (2 and 3 barg) and high (4–6 barg) pressure cases suggests aEffect of grinding nozzles pressure on particle and fluid

  • CoolGrind Technologies High Pressure Coolant Nozzles

    High pressure coolant nozzles for grinding, milling and turning machines CoolGrind pioneered the coherentjet nozzle in 1990 at the University of Connecticut Despite their low price, the laserlike quality of the jets is an industry leader, even the flat formed nozzleThe RotoJet jet milling machine is a fluid bed jet mill which features opposed grinding nozzles and a dynamic classifier Opposed nozzles reduce abrasion while the classifier rotor operates at variable speeds to provide ultimate control of the particle size distribution Capable of grinding dry powders to 05 – 45 micron averages with specific top size and/or bottom sizeRoto Jet | fluidenergy

  • An investigation into the effect of nozzle shape and jet

    22/05/2015· Circular, rectangular, and elliptical orifice nozzles were compared in terms of workpiece profile error, workpiece surface roughness, and grinding power over a variety of workpiece feedrates and cutting fluid jet pressures For the grinding conditions used in this research, it was observed that, although the circular nozzle performed best, higher nozzleJet milling is a common grinding method for high added value materials It is mainly used for materials which are abrasive or when the grinding process has to be carried out in ultra high purity conditions Extremely low wear rate of the mill parts provides more and more interesting new applications Comex jet mills incorporate the grinding chamber with air nozzles and theJMX Jet Mill Comex Group
