The editors of MICROmanufacturing magazine have compiled a series of videos focusing on various automated assembly aspects.

Kennametal Inc.'s GOdrillTM addresses drilling operations in a diameter range of 0.0394" to 0.5" in a broad variety of materials and applications, including the production of fuel systems or medical components.

Researchers at the Cockrell School of Engineering at The University of Texas at Austin say they have built the smallest, fastest and longest-running tiny synthetic motor to date. The team’s nanomotor is a step toward developing miniature machines that could one day move through the body to administer insulin for diabetics when needed, or target and treat cancer cells without harming good cells, the researchers said.

 

Precitech and Vision Research, both business units owned by Keene, N.H.-based Ametek Inc., have partnered with Levicron, a German manufacturer of air-bearing spindles, to create a slow-motion video of ultra precision milling.

Mohawk Innovative Technology Inc., Albany, N.Y., demonstrates a micromilling operation at 400,000 rpm with a 300µm carbide tool at a feed rate of 50" per minute.

 

A Stanford researcher has devised a method to wirelessly transfer power through living tissue to charge deeply implanted medical devices, such as pacemakers, in the heart and the brain.

Scientists have invented a method to make a high-powered lens that can transform a smartphone into a high-resolution microscope, according to researchers from the Australian National University (ANU).

Laser expert Dr. Ronald Schaeffer is releasing a series of educational videos titled, “Introduction to Micromanufacturing with Lasers.

In Part I, “Laser Characteristics,” he introduces types of lasers and parameters such as wavelength, pulse duration and pulse repetition rate, among others. He also describes the influence of these parameters on substrate type, feature size and material removal rate.

Leica Microsystems' Leica DCM8 optical surface metrology system is the latest evolution in non-contact 3D optical surface metrology. Designed to help maximize efficiency, the system unites the advantages of HD confocal microscopy and interferometry into one versatile dual-core system.

MAKLab, based in Glasgow, Scotland, hosts a wide range of digital fabrication tools and provides training and entrepreneurial opportunities to 16- to 25-year-olds seeking access to digital technology for their start-up businesses.

Advanced Tool Inc. talks about their trademarked Wear Analysis™ End Mills and a better method to process improvement and cost reduction in CNC Milling applications.

For Microlution Inc., which reports more than 100 micromilling and laser machining platforms installed worldwide, growth has been a constant since its inception in 2005.

Hexagon Metrology's Gary Hobart, the company's national sales manager, demonstrates the Optiv Performance multisensor optical measurement system equipped with a rotary table and a chromatic white-light sensor.

The miniature zinc die-casting process is described in this video from the Chicago White Metal Casting Co., Bensenville, Ill.

 

Laser frequency combs are high-precision tools for measuring different colors of light in an ever-growing range of applications such as advanced atomic clocks, medical diagnostics and astronomy—are not only getting smaller but also much easier to make.

 

New Scale Technologies Inc.’s ultra-compact M3-LS linear “smart” stage measures 28mm×20mm×9.5mm and offers 0.5µm resolution, less than 10µm runout and 1 mrad pitch and yaw over its 6mm travel range. The stage supports side loads of up to 20 grams without loss of precision or speed, and no separate bearing or guide mechanism is required, according to the company.

 

Micrometal GmbH, Muellheim, Germany, offers an overview of its photochemical machining process, which is said to be capable of fabricating very fine features. The continuous photochemical machining process "enables production of endless strips of metal parts on reels, which are fit for further processing (e.g. in the automobile industry)," according to the company's Website.

Custom Wire Technologies, Port Washington, Wis., is a contract manufacturer of precision medical wire parts that are custom manufactured from fine wire or ultra fine wires.

Cornell Universityresearchers have 3-D printed a working loudspeaker, integrating the plastic, conductive and magnetic parts. The loudspeaker is ready for use almost as soon as it comes out of the printer.

A new additive manufacturing process developed by GE can build-up parts as traditional AM methods can do, but it can also repair old parts and potentially extend the repaired part’s life cycle.
