Top 10 questions to consider

With different measurement technologies and thousands of sensor variants from which to choose, the answers to these questions help suppliers to decide which sensor is best for the application, says Glenn Wedgbrow, Business Development Manager at Micro-Epsilon UK.

Feature: Metrology

Quality innovation in healthcare D

uring the coronavirus pandemic, the medical industry demonstrated its resilience and ability to bring new products to market quickly. As we look to the future, how can medical device manufacturers streamline the journey from development to production, to enable future innovations in healthcare? Here, Mike G John, Head of Engineering at industrial metrology provider The Sempre Group, explains how integrating metrology into every stage of medical product development can accelerate the journey to market.

Metrology is fundamental in gathering evidence that the medical device meets safety and performance requirements for the patient, so manufacturers should prioritise developing an effective quality management system when producing new devices.

Feature: Adhesive thread locking

Solar plant underpins production & saves costs with adhesive thread locking T

hreaded assemblies, subjected to load and vibrations, are often locked against self-loosening by either a mechanical locking device or an adhesive thread locker – or a combination of both.

The merit of this is easy to understand when the assembly is in a motor-driven machine, where obvious vibration can cause an unlocked nut and bolt gradually to unwind. But what about a completely static object, like a solar panel? Surely, that’s a good example of a bolt-downand-forget application?

The short answer is no, it is not. Panels are exposed to a variety of weather conditions, and wind will cause enough vibration for the panel mounting bolts to

Standard L10 life expectancy calculation of a ball screw assembly

A ball screw consists of a threaded metal

Bearings are often specified to give an “L10” life. This is the life at which 10 percent of the ball screw assemblies in that application can be expected to have failed, due to classical fatigue failure or, alternatively, the life at which 90 percent will still be operating. The L10 life of the ball screw assembly is a theoretical life and may not represent the service life of the assembly. It can be calculated according to the following formula:

shaft with a nut that rides along its length as a motor rotates the shaft. The nut connects to a table, an arm or other load, as determined by the industrial process that is being automated. Recirculating ball bearings packaged, within the nut, contact the

heavy loads, long and reliable life, and minimum maintenance.

Characteristics of a high-load ball screw Thomson has developed a high-load ball screw by implementing a unique thread form that increases load bearing capacity by four to eight times over traditional ball screws. This gives the application engineer the option of deploying a ball screw in any application that previously required a roller screw. Or, because the life of the assembly is a direct function of the load capacity (see L10 Life Expectancy Calculation), using a high-load ball screw in a low load application would extend the life of the product.

Simplified set-up and operation make these electric drives perfect for simple motions between two mechanical end positions, without having to sacrifice electric drive motion characteristics such as pre-defined speed, gently cushioned movement into end positions, and selectable force for pressing or clamping functions.

Thanks to the intuitive, quick and easy commissioning directly on the drive, configuration doesn’t require any software or specific know-how. The motion can be simply controlled via digital I/O (DIO), like a pneumatic valve. End position feedback, similar to that from a standard proximity sensor or cylinder switch, is provided on completion of the motion.
