Yaskawa launches direct drive servo motor for ‘backlash-free’ automation applications

Yaskawa has introduced a direct drive servo motor that the company says packs a new level of performance into a more compact size than anything offered before. 

The new Yaskawa SGM7F line of direct drive servo motors delivers from 4 to 35 Nm of torque in a device as small as 2.1” high and 5.3” in diameter (53x135mm).

This size advantage makes it possible to apply the mechanical benefits of a direct coupling between a servo motor and a load in tighter spaces than ever before.  Continue reading Yaskawa launches direct drive servo motor for ‘backlash-free’ automation applications

Electric power: Clean energy infrastructure driving switch from AC to DC

Nikola Tesla was a famous scientist who developed alternating current, the means of distribution for electricity for the vast majority of devices, appliances and machines in households and factories and just about every other electrified thing in the world today. 

But even as Tesla was inventing much of the technology used in the alternating current electricity supply system, another famous inventor, Thomas Edison argued that direct current was the best way to distribute electricity.

By the time Tesla tech came onstream, DC had already been in use for a decade, but within a relatively small area, and Edison lost that argument mostly because the components of an alternating current grid enabled electricity to be carried far and wide beyond the power generating facility.  Continue reading Electric power: Clean energy infrastructure driving switch from AC to DC

OR Laser claims its 3D printing method will innovate jewellery industry

3D printing can produce complex shapes but the finishing when it comes to metal has not so far matched traditional manufacturing methods

OR Laser believes the jewellery industry will be the main beneficiary of Orlas Creator

OR Laser believes it is on the cusp of further innovate the jewellery industry with the introduction of its new and accessible metal additive manufacturing system, the Orlas Creator. 

OR says its Orlas Creator offers an “economically profitable” metal system with “superior speed and productivity gains by way of its unique” circular build-platform design in combination with a proprietary, rotation-led precision coater blade that will bring new value creation opportunities for jewellery brands.

During its 30-year history, 3D printing has already caused some serious disruption within the jewellery industry by facilitating new approaches to jewellery design and manufacturing.  Continue reading OR Laser claims its 3D printing method will innovate jewellery industry

Xerox launches new 3D printer featuring a nozzle ‘half the width of a human hair’

New Xerox 3D printers sport a nozzle which is almost too tiny to see with human eyes

Xerox says it has developed innovative architecture featuring tiny, stainless steel nozzles inside its new Direct to Object Inkjet Printer.

The company says this means it has created a new, label-less, on-demand method of personalising three-dimensional objects.

The nozzles are contained in print heads – about the size of a deck of cards – that accurately spray ink on objects as small as bottle caps and as large as football helmets. The printer can print on plastic, metals, ceramics and glass, eliminating the need for costly labels.  Continue reading Xerox launches new 3D printer featuring a nozzle ‘half the width of a human hair’

Additive manufacturing ‘revolutionising’ shipbuilding, says OR Laser

There’s a revolution brewing in the production of sliding bearings, according to OR Lasertechnologie

German industrial technology company OR Lasertechnologie says it’s only necessary to apply a layer of metal a few millimeters thick using the powder nozzle to reliably, cost-effectively, and easily protect the large shaft bearings used in ships from wear and tear. 

This represents something of a revolution in the shipbuilding industry, according to the company.

OR Laser says it develops and builds robot-assisted laser systems for direct metal deposition – which is similar to additive manufacturing – that take the production and repair of sliding bearings to an “innovative new level”.  Continue reading Additive manufacturing ‘revolutionising’ shipbuilding, says OR Laser
