NASA’s Ames Research Center – Robert Walker

At NASA’s Ames Research Center we study the chemistry of astronomical objects within our Solar System and beyond. We use a vacuum system that was designed to reproduce the ultra low temperatures and vacuum of outer space. This is done with diffusion pumps for vacuum and a special refrigeration unit we call the “cooler”. To access parts for maintenance we must periodically lift the cooler out.

The Sky Hook Model 8570 portable lifting device is an ideal “lifting parts system” for this application.

Before Sky Hook we were limited to using coolers that only weighed 15 lbs. which were lifted out by hand. It sounds easy, but not everyone could handle these smaller systems because of the attached high pressure helium lines. Obviously this method of lifting machine accessories or coolers was not ideal. Also, because using this method to lift parts was so awkward, occasionally someone would damage the sensors on the cooler.

With helium hoses connected, the newest cooler weighs over 40 lbs and is even more awkward to handle. Back injury prevention is always a consideration (so it would be very impractical to lift the unit up by hand to remove).

I knew we needed a portable lifting device that would allow us to lift the cooler straight up with ease, and then swing it around to the cart for maintenance. Sky Hook 8570 provided the perfect solution to all our problems.

When the research scientists saw the Sky Hook 8570 in use, they all agreed that it was a fantastic lifting parts system.

There was one unexpected bonus–as you can see in the close-up picture of the cooler–we are able to stop lifting at any point. Here you can see the gold-plated window holder which can easily be cleaned, then lowered back into the vacuum chamber.

This alone is a big time saver AND far less awkward, because on the smaller 15lb units, the Cooler has to be completely removed and placed on a table–at the same time by hand-and at the same time deal with helium lines.

Another great feature is the ability to rotate the cooler 180º, and lower it through the hole in the lift cart (where it can sit for more work that might be required).

Manufacturers in search of precision gear solutions or productive tooling for CNC lathes should stop by booth 2022 at CMTS 2015, taking place September 28 – October 1 at the International Centre in Mississauga, Ontario. Here, EXSYS Canada Ltd. will showcase the latest gearboxes, tool holders and adapter systems it offers from EPPINGER.  

Suited for a range of applications, including machinery, automation and robotics, EPPINGER’s compact, high-transmission gearboxes meet strict demands for stiffness, efficiency and performance. These precision gearboxes come in a variety of types, including bevel, hypoid, planetary and cycloidal designs, to bring smooth, reliable operation to a variety of industry segments.

Designed for use with all major machine tool brands, the EPPINGER Dual Collect Chuck is a double spindle tool holder that expands the capacity of individual turret positions on a CNC turning center. With two live tools in one turret station, shops can reduce their job setup times and increase tooling versatility for different workpieces.

EPPINGER Slim Fit tool holders accommodate VBS 24-station turrets on Haas CNC lathes. The compact housings of these tool holders allow shops to utilize all 12 bolt-on and 12 VDI stations for maximum tooling space and optimal productivity. Available in radial right angle and straight axial configurations with coolant capabilities, the holders have a lightweight, yet rigid design that minimizes the stress put on the machine turrets.

With the EPPINGER Gear Hobber attachment for all machine tool brand live-turret stations, shops can achieve single-setup, one-operation gear cutting capability when generating splines, spur or helical gears. The attachment’s adjustable toolholding system eliminates the need to rough gears on one machine then transfer them to another for gear hobbing. To compensate for different types of grooves and pitches in splines and gears, users simply adjust the vernier dial to the applicable settings.

When it comes to turning operations, shops can significantly shorten their changeover times with the EPPINGER PRECI-FLEX® modular quick-change tooling system. The system incorporates selections of adapters engineered to hold a variety of cutting tool types and shank designs. The adapters have a common connecting feature that locks into standard base units mounted on a turning machine’s turret.

PRECI-FLEX lets shops preset tools in adapters offline then quickly and easily switch the tool/adapter assemblies in and out of the base units. Tool positions repeat exactly within +/- 3 µm, eliminating the need to re-center, touch off or make test cuts after a tool exchange.

Another advanced form of modular quick-change tooling technology EXSYS offers is the EPPINGER Compacto™ C3, C4, C5 and C6 base holder. When compared with traditional base holder designs, the compact size of Compacto provides more space for machining in tight workspaces as well as offers improved torque transmission and rigidity for increased tool accuracy. The holder’s polygon shape connection (PSC), which is the shortest PSC interface in the industry, further adds to the system’s precision and stability.

 

About EXSYS Tool:
EXSYS Tool, Inc. is the exclusive importer of German-made EPPINGER solutions, including high-precision live and fixed toolholders for CNC turning centers, modular adapter systems for quick lathe tooling changeovers and gear box solutions for a wide range of applications. EXSYS Canada Ltd., located in Brampton, Ontario, operates as an extension of the EXSYS Tool Inc. headquarters in San Antonio, Florida, and provides manufacturers throughout Canada with applications support and repair work on all makes and models of live tooling.
