Precise Positioning with Shorter Settling Times: Leveraging the Rolling Spring Effect of the LM Guide
Positioning technology is a crucial element of manufacturing. The ability to quickly and accurately stop at a specified position is particularly important for production floors that require precise position resolution. Here, the concept of “settling time” is key. Settling time is the time the machine spends repeatedly making minute adjustments before it reaches its target position. Because long settling times drastically impact product quality and processing efficiency, shortening them is crucial. In this article, we’ll take a deeper look at control technology used to shorten settling times in precision positioning systems that make use of the LM Guide.

Numerical Simulation Technology for Enhancing LM Guide Accuracy
The LM Guide first debuted on the market in its current form in 1973. During the just over 50 years since, it rapidly became ubiquitous around the world in machine tools and a variety of other fields besides. Today, the LM Guide is essentially synonymous with linear motion and its use is widely taken as a given. That said, the changing needs that have accompanied market expansion have been the impetus for a wider range of available sizes, more varied product concepts, and numerous combinations of optional features that have collectively resulted in a vast variety of LM Guide products on offer. From a customer’s perspective, though, selecting the appropriate LM Guide to build a machine that meets their requirements from this vast array poses a challenge. There are performance factors like service life and rigidity as well as dimensional constraints to consider, to say nothing of cost and lead times that must also be taken into account. This is where THK steps in as a manufacturer to offer different types of technical support.

Exclusive Look at the Internal Structure of the Pick and Place Robot (PPR)
We're now in an age where every single thing you own—from smartphones and computers to household appliances and cars—contains electronic components. Everyone is probably familiar with the image of electronic components as circuits that move machinery, which are made by soldering components onto a green circuit board. But do you know just how small those components have become? Looking at typical components as an example, the smallest resistors and capacitors are 0201 size (0.2 mm × 0.1 mm). At this granular size, it's becoming difficult to pick them up even with tweezers. The smaller and thinner they get, the more difficult it becomes for production equipment to handle them, which causes a bottleneck in transfer processes. In this article, we’ll take a look at how the Pick and Place Robot is optimized for assembling and transferring these kinds of tiny electronic components, which will include a rare peek inside the structure of this product.
