[Aluminium Network] A few days ago, Canadian plasma-based PyroGenesis (hereinafter referred to as PG) announced that it will publicly demonstrate the analytical test performance of its launch of 3D printed titanium alloy powders. The experiment will use sophisticated digital imaging technology to analyze and include Results of sphericity, density, and purity. According to Xiaobian, this is the second company in the world to use plasma technology to produce 3D printed metal powders. During the testing process, PG's titanium powder will be scanned using Nikon's X-ray m-CT system, which is 1.1 cubic microns relative to the pixels' voxels, and will use an intuitive multi-scale multimodal image data detection platform. The aspect ratio, equivalent diameter, volume, and porosity of the powder were evaluated. The chief technical officer of PG said that it will also demonstrate the use of selective laser melting (SLM) printers to print parts on site and test the performance parameters of the parts to evaluate the titanium powder produced by plasma technology. Generally speaking, the shape of the metal powder is often irregular, and the shape often appears angular or serrated, so that they appear to be connected to each other when passing through a hose or on a printing bed. The spheronization of metal powders is a process of melting and reshaping the metal particles during their flight. Specifically, the metal powder is sprayed into an induction plasma stream. At an extremely high temperature, these powders melt immediately and then automatically become spherical under the effect of surface tension. These spherical liquid metal droplets, once they leave the plasma stream, immediately cool and harden into spherical particles. In February 2016, LPW Technology, a global manufacturer of plasma spheroidizing powders and the manufacturer of metal powder materials and technologies in the United Kingdom, was officially put into operation. At that time, in addition to producing tantalum, tungsten and titanium alloy powders including Ti-6Al-4V, they also targeted refractory metal powders such as molybdenum, niobium, and other nickel-based superalloys. The benefits of spheronization of 3D printed metal powders More importantly, the fluidity of the material is greatly increased, and the perfect spherical shape results in a more compact accumulation of the powder. When this powder is used on a powder bed technology based 3D printer, the resulting parts have better density and strength than untreated powder. In addition, the level of contamination on the surface is significantly reduced compared to conventionally atomized powders, which not only means that the extra titanium powder in the manufacturing process can be reused many times, but also can further improve the flowability of the powder. It also produces 3D printed parts that are more robust and have better mechanical properties. In addition, the use of plasma spheronization technology to produce metal powder material has an added benefit that excess material is recyclable. Especially those powders with increased oxygen content after being used several times on a metal 3D printer. Drill just rely on the motor to drive the drive gear to increase the strength of the drill bit rotation, so that the drill bit metal, wood and other materials to do the form of scraping holes.

The impact drill is equipped with adjusting knob,adjustable drill and impact drill in two ways. But the impact drill is used on the inner shaft gear beating each other to realize the impact effect, but the impact is far less than electric hammer. It can also drill reinforced concrete, but the effect is poor.
Hammer Drill is not the same, it is the use of the bottom of the motor drive two sets of gear structure, one to achieve it drilling, while the other is driven piston, like the engine hydraulic stroke, resulting in a strong impact force.
