I didn’t observe high frequency vibration by fixing the x ends. There’s still some banding when I light the layers with a led light but it’s in the order of 0.1mm or less, most likely caused by inconsistent extrusion motion, step stick or filament diameter.

To comprehend Global (United States, European Union and China) 304 Stainless Steel market dynamics in the world mainly, the worldwide Global (United States, European Union and China) 304 Stainless Steel market is analysed across major regions. HTF MI also provides customized specific regional and country-level reports for the following areas.

Well it grew pretty linearly, at least in the early stages, and then it became an algorithmic thing, because one sells one, two sells four, four sells eight, that type of thing. The curve starts going up.

After the appropriate holes have been made, the meteorite dial is once again polished to remove any blemishes created by drilling and it is then removed from the work plate. Any slips and the entire dial has to be discarded and the whole process repeated.

For perspective, Chinese steel production capacity exceeded 1.1 billion tonnes in 2013, equivalent to the steel capacity of the rest of the world combined. Since then, China has pledged to cut 100 million to 150 million tonnes of capacity by 2020, having cut 140 million tonnes from outmoded induction furnaces in 2017.

While most fiber lasers sold today are in the 1 to 6 kW range, higher powered configurations are making inroads in select applications and will continue to grow in market presence. Brendon DiVincenzo, product manager for lasers and automation at Bystronic Inc., Elgin, Illinois, commented, “steel service centers have welcomed the advent of higher powered units that currently have an operating capability in the 10 to 12 kW range. As speeds increase, we will see greater demand.”

The joining of dissimilar metals has long been a challenge for welding and design engineers who have often been told that it’s difficult or that it can’t be done. Every welding handbook contains a table showing the allowable combinations of materials that can be welded—and those that can’t. As any metallurgist will tell you, it is the combination of physical properties and metallurgical incompatibility that governs weldability. However, there has always been a lot of interest in this area because there are a lot of potential applications that require such joints, particularly bright metals to steels and aluminum alloys. Over the years, this has prompted a significant research focus in this area—innovation has been incremental, so it’s still work in progress. SPI Lasers’ nanosecond welding process (patent pending) has provided a differentiated mechanism that has to date proven itself to be extremely capable in joining a wide variety of dissimilar metals (FIGURE 1).

The Showa shock features a 50mm shock body and an 18mm shock shaft. Pro Circuit had added a bladder cap and a special HSS coil spring. Bones told us that while the HSS steel coil-spring shock is not available to the public yet, it will be soon. It offers the springy feel of a titanium spring without the worries of the spring rate being off. Additionally, although made from steel, its weight is closer to that of a titanium spring than to a typical steel spring.

Controls and software have made a huge difference in coil processing. Software systems can calculate a nest based on the optimum cutting pattern for a particular coil width, as well as determining the coil width that will offer the best yield. Finn explained, “The final nest is dependent on the coil feeding process. The leading edge must match the ending edge. To ease adoption, we have developed software to automate nesting and cutting path optimization. This makes it less intimidating when bringing lasers into your operation.”

At least in the rifle department, an avalanche of new shooting equipment is being chambered for a bullet known as the 6.5 Creedmoor. Every hunting, long-range target and semi-automatic tactical weapon builder I examined in magazines and online after the enormous Las Vegas SHOT (Shooting, Hunting, Outdoor Trade) Show last January had added a rifle chambered for the 6.5 Creedmoor cartridge. This shooter obviously does something particularly special.
