Since "the business started last year was not very good," Li Binyu, the owner of the cabinet store in Xiaoximen Building Materials Market in Changde City, Hunan Province, quit the helper in the store the day before yesterday. This is the bleak picture of the building materials and home furnishing industry. Yesterday (August 30th), the National Building Materials Home Furnishings Index (BHI) released by the Department of Circulation Development of the Ministry of Commerce and the China Buildings Association (601668, shares) showed that the cement manufacturing profit fell year-on-year from January to June this year. In half, the profit of the flat glass manufacturing industry plummeted by more than 100% year-on-year. In the past, the home market of the car that had been unable to stop the car, the blindness of the blind expansion at this time became increasingly serious. According to the latest BHI data released in 2010 and reflecting the macroeconomic index of the building materials and home furnishing market, the total profit of the cement manufacturing industry in the first half of the year was 22.28 billion yuan, down 51.4% year-on-year. The most glaring figures come from the glass industry. The output of flat glass of enterprises above designated size nationwide was 366 million weight boxes, down 3.1% year-on-year. From January to June, the profit of the flat glass manufacturing industry was 490 million yuan, a year-on-year decrease of 118.5%. At the same time, inventories rose by 26.1% year-on-year to 44.75 million weight cases. The glass reflects the real estate construction and operating rate. Regarding the reasons for the sluggish flat glass market, Meng Guoqiang, president of the China Building Materials Circulation Association, concluded that the data on real estate construction in the first half of the year was not good, and the control efforts were not diminished. The glass industry, which had already had overcapacity, was “difficultâ€, resulting in increased stocks. . In addition, continued rainfall in most parts of the country has also weakened the glass market.
Diamond Grinding Heads
Diamond grinding head: A kind of stone material, ceramic materials and other non-metallic materials of grinding tools, especially involving a with diamond alloy grinding tools for grinding body, it includes substrate and a mill body, in which several mill body clearance to fixed to the substrate, the grinding surface of the grinding head grinding body also set a clearance, among them, the substrate is best by a certain toughness of adhesive materials, The abrasive body is preferably made of diamond alloy material. The utility model has the characteristics of high grinding performance, simple manufacture, low cost, high grinding quality and can be applied to large-scale grinding
Through the processing of various workpiece, to achieve grinding, grinding, polishing effect; According to the use, mainly divided into the following types of grinding head:
1.grinding class: mainly installed in the grinding machine grinding head, the workpiece for grinding, grinding, grinding, processing can be divided into rough grinding and fine grinding.
2.grinding class: generally used for grinding the burr of the workpiece, or the workpiece surface precision is not high processing. Use grinding machine, electric, pneumatic and other tools to high-speed operation to achieve the effect of grinding.
3.polishing class: specially for surface finish (roughness) processing and use of higher requirements, is the need for separate processing process.
