It is reported that Qingdao Heshun built a series of 6,600 tons of dry cargo ships with a total length of 103.7 meters, a width of 17.2 meters, a depth of 8.5 meters, a design draft of 6.6 meters and a speed of 12.5 knots. The 6600 ton dry cargo ship type was designed and developed by Qingdao Heshun Shipbuilding Co., Ltd. Its cabin capacity is more than 1000 cubic meters more than the same tonnage freighter. Compared with ships of the same type, comprehensive energy saving is the biggest advantage, the fuel consumption is the lowest, and the speed is relatively fast, which is highly praised by the shipowners.
Milling is refers to the use rotating multitool cutting workpiece, processing method is efficient.Tool rotation (background) at work, the workpiece moving (as a feed movement), artifacts can also be fixed, but at the moment, rotate tool must also move (at the same time to complete the main motion and feed motion).Milling machine has a horizontal milling machine or vertical milling machine, large gantry milling machine.These machine tools can be ordinary machine tool, can also be a CNC machine tool.[1] with a revolving milling cutter as the cutting tool.Milling is generally conducted on milling and boring machine, suitable for processing plane, groove, all kinds of forming surface and mould special shape, etc.
