Dry Cleaning System Delivers Energy Savings Dürr EcoClean's EcoCVac ofers an efective dry cleaning system designed to eliminate the need for compressed air. The system can provide energy savings of more than 50 percent and, because maintenance of the work- ing chamber is minimized, it also improves the ma- chine availability. The EcoCVac system includes a pressure vessel connected by a pipe to the vacuum chamber in which the part is placed. Once the chamber is closed, a powerful airfow catches the chips stick- ing to the part and takes them into the vacuum vessel. A chip clean-out device then separates chips and emulsion, enabling both to be discharged separately into a collecting bin and a fume, respectively. The company says the system afords reduced energy consumption compared with compressed-air type equip- ment, leading to a cost reduction of more than 50 percent. In addition to the cost benefts, the EcoCVac has improved process reliability. As the chips are removed not only from the part but also from the work chamber, the risk of recontamina- tion is minimized. The chamber is then cleaned less ofen at a reduced cost. Unlike conventional compressed-air systems, there are no nozzles to be aligned relative to the part. Dürr Ecoclean Inc. /248-560-2100 / durr-ecoclean.com Engineered Compound Purges Resins in 3D Printing Dyna-Purge, division of Shuman Plastics Inc., has partnered with 3Dom USA of Fargo, North Dakota, to intro- duce "Dyna-Purge 3D Clean," a non-abrasive, non-chemical, engineered thermoplastic purging compound specially formulated to purge all resins used in 3D printing. This part is designed to be easy to use before or afer printing a part, for color changes, resins changes, especially composite materials and for preventive machine maintenance. According to the companies, Dyna-Purge 3D Clean is designed for a variety of 3D printing applications including plastic proto- typing, multi-color 3D prints, low volume production and others requiring multiple color and resin changes for a range of systems. Dyna-Purge / 716-685-2121 / dynapurge.com Spray Gun Catalog Provides Detailed Technical Reference Spraying Systems Co. provides a publication featuring spray guns and a detailed technical reference section on spray tech- nology. GunJet Catalog 75 provides specifc information on hundreds of low-, medium- and high-pressure GunJet spray guns that are used for cleaning and rinsing applications. In addition to product information, the catalog includes cross-reference tables to simplify matching extensions, adapt- ers and spray tips for spray guns. Another section is comprised of an extensive list of spare part kits for each GunJet model. Spraying Systems Co. / 800-957-7729 / spray.com Guyson Corp.'s Robotic Lance Blasting System is designed with an extended lance nozzle for precision grit blasting and surface preparation of the inside diameters of industrial gas turbine components in manufacturing and repair operations. A Fanuc M-710iC robot is integrated into the blast system as the lance manipulator in an expanded process chamber with a servomotor-driven rotary table that is controlled as an auxiliary axis of robotic motion. To enable processing of components with difer- ent surface roughness specifcations, the custom blast machine is designed with an enhanced media reclamation and delivery system for two diferent grit sizes, including a sep- arate cyclone separator, classifer and pressure pot for each. The change-over from one grit size to the other is accom- plished in less than fve minutes, and the selected media, as well as the status of all valves and elements of the media delivery system is automatically detected and displayed at the touch screen human-machine interface. A 500-pound-capacity jib hoist is mounted over the crane slot in the roof of the blast cabinet to facilitate safe and convenient loading of heavy work pieces. Custom-designed interchangeable fxtures with locator pins and quick-change hardware accurately secure the work in the correct position for repeatable robotic blasting. The robot motion program was created using customer-sup- plied solid models of the components and fxtures. The entire blast system was also solid modeled and all the data brought together using advanced ofline robot programming sofware to generate the robot tool path. Nozzle stand-of, lead and lag can thus be adjusted with a quick parameter change. This method ofers a time advantage over teach pendant programming, and for robotic blast systems in production use, the beneft of not idling the machine.
