Traditional manufacturing processes alter forms through material removal, heat or mechanical force. But in generative or additive manufacturing, structures are built up layer by layer. Laser additive manufacturing, electron beam melting and laser metal deposition are all types of additive manufacturing processes.
Because metal additive manufacturing processes are complex and require extensive material and process knowledge, it can be difficult for a metal fabricator to see how or when 3D printing might fit. To help make sense of it all, let’s consider the basics of additive manufacturing and 3D printing and how it all relates to metal fabrication.
The best way to prevent issues with collets is to simply keep them clean by removing swarf, particles, coolant residue and oil. (first view)
There are three particularly sensitive areas of the tool holder assembly that can experience process-affecting wear and tear and cause a cycle to change. By identifying and addressing issues early in these areas, you can prevent small tool holding imperfections from turning into bigger problems.
The perfectly fitting beak prosthetic was secured in place on the bird with bone cement and colorful rhinestone-styled orthopedic screws. The bird was able to try out the beak within 48 hours and made a full recovery while awaiting placement at a zoo. (first view)
The durability and strength of metal, coupled with a nimble approach to product development and reduced lead times, are driving the widespread adoption of metal additive manufacturing for orthopedic care and prosthetics. Here is one example where 3D metal printing recently proved to be a truly lifesaving process.
Mechanically generated mists are produced by processes that do not generate excessive heat, like metalworking lathes. They are usually around ten microns in diameter and are relatively easy to capture due to their large size. Most inexpensive oil mist control systems on the market are aimed at mechanical oil mist collection. Membrane-based collectors (which use a disposable fiberglass membrane filter) and centrifugal mist collectors can remove up to 80 percent of mechanically generated mists. (first view)
Coolants and lubricating fluids are essential to metalworking operations. But if they are allowed to accumulate in the air, they can become a significant health and safety hazard. What can you do to minimize your risks?
