3D Printing Is Already Starting To Threaten The Traditional Spare Parts Supply Chain

Gilles Roucolle and Marc Boilard for Forbes: Â The race is on to use 3D printing to produce small-series parts, on demand and on location, for industries from aerospace to automotive. At stake is the shape of a $400 billion market for spare parts manufacturing and logistics. And those changes are not 20, or even 10, years out - they are happening now. Using models built through computer-aided design (CAD), 3D printing can produce virtually any solid object, even those with complex architectures, and in a range of materials, including plastic, ceramic, and metal. Currently, about half of 3D printing - also known as additive manufacturing - is used for prototyping. This saves manufacturers time and money, because they can develop new components or products on-demand, with less waste and without expensive tools and molds. Â Cont'd...

Desktop Factories: A 'Moving' Look at 3D Printing

Precision mechanical movement is an essential attribute of 3D printers. Stepper motors provide this control to many 3D printers thanks to their relative ease of use and competitive cost.

Maintaining Precision At Varying Temperatures

High precision transducers are increasingly in demand due to high-performance industrial applications such as precision motor controllers, metering, measurement accessories and test equipment for medical equipment such as scanners and MRI machines.

Selecting Pneumatic Linear Slides for Automated Assembly Equipment

Rather than sizing up to a slide model with very large diameter guideshafts, you may be able to use a smaller model with the addition of the optional center support.

Comparing Three Different Types of WirelessHART Adapters

Transmitting small amounts of data over long distances is one of the challenges in process plants.

T.J. Davies' Retention Knobs

T.J. Davies' Retention Knobs

Our retention knobs are manufactured above international standards or to machine builder specifications. Retention knobs are manufactured utilizing AMS-6274/AISI-8620 alloy steel drawn in the United States. Threads are single-pointed on our lathes while manufacturing all other retention knob features to ensure high concentricity. Our process ensures that our threads are balanced (lead in/lead out at 180 degrees.) Each retention knob is carburized (hardened) to 58-62HRC, and case depth is .020-.030. Core hardness 40HRC. Each retention knob is coated utilizing a hot black oxide coating to military specifications. Our retention knobs are 100% covered in black oxide to prevent rust. All retention knob surfaces (not just mating surfaces) have a precision finish of 32 RMA micro or better: ISO grade 6N. Each retention knob is magnetic particle tested and tested at 2.5 times the pulling force of the drawbar. Certifications are maintained for each step in the manufacturing process for traceability.
