3.High-end three-dimensional flexible robotic cutting applications, to achieve bevel cutting function, the pipe and the torch using the servo positioning function .Can cut carbon steel, stainless steel, copper, aluminum and other pipes and profiles, such as: the tube, pipe, oval pipe, rectangular pipe, H-beam, I-beam, angle, channel, etc. The device is widely used in various kind of pipes profile processing field, shipbuilding industry, network structure, steel, marine engineering, oil pipelines and other industries.What are acoustics? Sound absorption, absorption area, absorption coefficient, speech intelligibility,          reverberation time. There are many relevant factors involved in acoustics. But what we all want is pleasant sound rather than noise. This is where it’s important to focus on achieving the right reverberation time – how long sound takes to abate in a room. When sound is absorbed, it provides a short reverberation time and thus good            acoustics and high speech intelligibility. The optimal reverberation time depends on the purpose of the room. E.g., the optimal reverberation time for a church is typically 6 seconds, while a living room in a private home, on the other hand, should achieve a reverberation time of only 0.6 seconds. The shortest reverberation time possible is not always necessarily what we should aim for. Insufficient reverberation time can quickly make the sound in the room seem dull, and conversely, excessive reverberation time can result in unwanted echoes and         impaired speech comprehension. A long reverberation time is typically perceived in an unfurnished room in a house. Improve your acoustics There are many ways to achieve improved room acoustics. Some of the common         methods are furniture, carpets, sofa cushions, heavy curtains etc. A good reverberation time can therefore be difficult to achieve with minimalist decor, where the use of        carpets and furniture is sparse. Acoustic panels used as replacement for hard walls can be a good solution. In addition to being absorbent, acoustic panels also have a diffusing effect. Diffusers can split the sound waves when the sound is reflected, making the sound more           evenly distributed throughout the room. This is perceived by the human ear as a more pleasant room acoustics.1.all-round 360 production line cutting group stop workflow, enabling automatic tube feeding, automatic feed, automatic cutting, automatic transmission operation. 2.Using KASRY Nesting programming system as a major programming tool, the software programming platform AUTOCAD basic, simple, graphical and intuitive, feature-rich, it can greatly improve operational efficiency.
