What is the best type of robot controller?
The current trend of robot control is changing with PLC-based systems offering different benefits and opportunities over the traditional dedicated robot controllers. So what needs to be considered when selecting the right option for the application? Barry Weller, Product Manager at Mitsubishi Electric, looks at how to determine which robot control option is best.
Ensuring surgical motors will withstand 500 sterilisation cycles
There are few industries that push the limits of engineering further than the manufacture of surgical power tools. Design engineers are constantly pushing the boundaries of ergonomics, precision, size and reliability in order to release the latest life-saving device onto the market. Fortunately, Portescap has launched a range of 15 new motors that are designed specifically for surgical applications.
Condition monitoring for predictive maintenance concepts
The system from Nord Drivesystems regularly or permanently records drive and status data in order to optimise the operational safety and efficiency of machines and plants. Based on this information, concepts for predictive maintenance can also be developed. Fast, efficient and comprehensive evaluation of analogue and digital data (measurements, signals and operating parameters) by the intelligent PLC in the drive electronics forms the basis.
Benefits of black oxide finish for rolling bearings
Black oxide finish has a long tradition. It forms a protective layer for steel parts. David Schaljo, head of application engineering with NKE in Steyr, Austria, explains the benefits and illustrates them with practical examples.
What can graphene do for lubricating bearings?
Design engineers have long searched for material coating methods to reduce friction. But, could the restructuring of newly found materials reduce friction on macroscopic scales? Here, Chris Johnson, managing director of EZO bearings supplier SMB Bearings, explains how future surface treatments, including innovations in graphene and grapheme-related materials (GRM) could enable better, or limitless, bearing wear.
Gas flow control: how to balance cost against specification
Within the field of gas mass flow control there are several manufacturers vying to supply their equipment into industry. Each has their own strengths, and each has their own weaknesses, although all have their merits within their chosen industry sector or application segment. An alternative view is to take a given flow control process and then apply the best, most cost-effective, technique or solution within the constraints of cost:specification balancing.
Maximise bearing life by considering load-carrying capacity
Chris Johnson, managing director of SMB Bearings, explains bearing loads – and how a bearing’s ability to deal with it can help maximise bearing longevity.
Should you use a safety PLC or a standard PLC and safety relays?
When Apple released the iPhone X in 2017, some critics suggested the improvements compared with its predecessor were not worth the extra cost. However, if you could benefit from facial identification and an OLED display, the iPhone X may be a good choice. Manufacturers must also consider the specifications they need when choosing between a standard programmable logic controller (PLC) and a safety PLC. Here, Bernard Zwickler, director of automation parts supplier EU Automation GmbH, explains.
