According to reports, ultra-precision mirror processing of large metal plane workpieces has been the goal of testing, military, aerospace, equipment manufacturing and other fields. At present, most of the mirror processing equipment that can be inquired internationally can only be used for ultra-precision machining of small parts or by manual polishing and grinding, and the surface roughness of the finished product is difficult to reach ultra-precision level, that is, Ra0.05 or less.
The ultra-precision milling integrated machine tool developed by Huagong Machine Tool for Baosteel is the first milling and grinding process on the surface of ultra-low carbon steel produced by Baosteel. The steel has a low carbon content and also contains materials such as ruthenium, titanium, aluminum, etc. The material of the steel slab is particularly soft, has a large deformation amount, and is very difficult to process. The machine adopts the integrated milling technology. Through milling, rough grinding, semi-finishing and ultra-precision grinding, the mirror processing of the entire billet can be efficiently performed in 3 hours. The experts who came to the inspection said that the feed grinding of 0.01mm (mm) can be achieved on the heavy machine with more than 40 tons and 12 meters long, indicating that the Huagong machine tool has the ability to manufacture ultra-precision machine tools; The mirror effect below Ra0.02 ensures Baosteel's full-end metallographic inspection of the entire billet, providing a reliable guarantee for the production quality of steel materials.
Oriented Strand Boards or OSBs are engineered wood panels where rectangular wood stands are arranged in cross oriented layers and binded together with resin.
Luli Group Co., Ltd, has the capability and capacity to produce High Quality OSB yet with competitive pricing. It is the result from the huge investment into latest cutting edge technology from Germany – the world leader in technology, engineering and innovation.
