Nexen, CNC melhor? E uma Pinball de Lego, projectos, Vídeos Gingery, e 3D para a Quinta!

Nexen!
Em vez dos Parafusos, lentos, ou das correias, relaxadas, o melhor de 2 Mundos, um movimento linear de precisão, mas que aguenta muito...
Bacana!



Nexen Enhances Roller Pinion System With Increased Torque Capacity
Editor Design World

Nexen Group, Inc. has improved its revolutionary Roller Pinion System (RPS) by significantly increasing its torque capacity. With up to 60 to 140 percent more torque capacity*, the RPS offers industry-leading power density for precision linear motion control applications.
“In the past, the market has used the phrase ‘power density’ to differentiate similar motion control solutions,” said Tony Kliber, Lead Project Engineer Precision Automation Components, Nexen Group, Inc. “The new torque capacity ratings eliminate this factor, allowing our customers to reduce the size, cost and weight of their machines without sacrificing superior linear positioning performance.”
Nexen’s RPS offers linear positioning with zero backlash for high-precision motion control applications. With more than 99 percent efficiency and a long operational life of up to 60 million pinion revolutions, the RPS yields up to 36 million meters of travel. Differing from a traditional rack and pinion system, the RPS features a roller pinion/toothed rack combination. The pinion is comprised of bearing supported rollers that engage a unique tooth profile. Each tooth profile is measured to ensure high positional accuracy and eliminate cumulative error. Racks are available in standard 1-meter and ½-meter cut lengths or can be custom cut to certain lengths, leaving no limit to travel distances.

Dos nossos amigos da 3D Printing, vem esta Dica, uma série de Livos Antigos, que ainda hoje são úteis, dos quais, The Boy Electrician, e The Boy Mechanic:









Public Domain Technical Books
This is a scanned version of The Boy Electrician, 1913 version. This book is in the public domain. Currently it is in scanned form, but the eventual goal is to use OCR software to convert it to real text plus images. If you need the original TIFs (which are huge), send me an email.















Estou sempre a insistir nestes Livros da Série Gingery, mas é assim que eu sou!

O que eu sei, é que estes Livros fazem falta a qualquer Engenhocas, porque não só vos permitem construír Máquinas-Ferramenta, como vops podem inspirar para sabe-se lá que mais outras máquinas, como por exemplo...
Impressoras 3D!







The Best Gingery Lathe Video Series To Date
Gerrit Coetzee

Makercise] has been working on a Gingery Lathe since September last year. His videos on the process are by far the most detailed, clearly shot, and complete series on making a Gingery lathe we’ve come across.
For those who aren’t familiar, the Gingery series of books describe how to build an entire machine shop’s worth of bench top tools using only the hardware store, dumpster dives, charcoal, and simple skills. The series of books start out with the charcoal foundry. [Makercise] has built a nice oil fired foundry already so it’s off to the next book, Gingery 2, is the metal lathe.
The Gingery books and, really, most DIY books from that era are: not well laid out, well written, or even complete. All but the most recent prints of the series still looked like photocopies of typewritten documents with photos glued on. The series provided just enough detail, drawings, and advice to allow the hobbyist to fill in the rest. So it’s really nice to see someone work through the methods described in the book visually. Seeing someone using a scraper made from an old file on aluminum to true the surface is much more useful than Gingery’s paragraph or two dedicated to the subject.

3D printing for agriculture: Top 7 of the best projects
Lucie Gaget

Additive manufacturing is a great asset for many different industries and can be used for various applications. You may not know it, but agriculture is one of the industries starting to make the most of the cutting-edge technology that is 3D printing. You will see in this blog post what are the benefits of this technology for agriculture and what are the most innovative projects developed in this sector. From urban gardens to 3D printed tools, we will see how additive manufacturing is helping the development of agriculture. Follow the guide.
