new small series of standard-sized crest-to-crest wave springs enables
original equipment manufacturers to reduce the size of their assembly by up
to 50 percent, while maintaining the same amount of force and deflection as a
regular coiled spring. Smalley offers more than 4,000 standard wave springs
in 17-7 stainless steel or carbon steel. The new Crest-to-Crest series is
available in dimensions from 0.25 to 2.00 inch.
This design eliminated the need
to keep wave crests aligned, eliminating use of a key locating device or use of
a shim inserted between individual springs. The wave peaks hold their configuration
because the spring is integrally formed. Crest-to-crest wave springs are made
with plain and shim ends.
Smalley has expanded its flat
wire rolling mill operation in Illinois
to meet growing demand for various raw material sizes. A vertical integration
has evolved into the production of hundreds of material cross-sections in a
wide variety of alloys. Springs can also be made in exotic metal alloys.
Unlike rings and springs that
are stamped through the metal grain, Smalley's edgewound retaining rings and
wave springs have a circumferential metal grain structure that is said to give
them improved strength, dimensional stability, and performance characteristics.
A new service lets engineers and orthopedic surgeons design and 3D print highly accurate, patient-specific, orthopedic medical implants made of metal -- without owning a 3D printer. Using free, downloadable software, users can import ASCII and binary .STL files, design the implant, and send an encrypted design file to a third-party manufacturer.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
