Yesterday, the reporter learned from the operation analysis of the third quarter of 2013 and the forecast and warning information of the key industries held by the Hebei Provincial Federation of Industry and Economics. The LED industry in Hebei Province showed a rapid growth from January to September, among which the provincial capitals performed well and were strong. Drive the development of the industry.
Our province has a complete LED industry chain from semiconductor epitaxial wafers, die manufacturing to various application lamps. The provincial information industry and information technology association makes full use of the advantages of close contact with enterprises, and has held several product development collaboration meetings to promote LEDs. The industry is developing rapidly. From January to September, the main business income was 1.726 billion yuan, a year-on-year increase of 64.32; the total profit and tax was 231 million yuan, a year-on-year increase of 17 times; the foreign exchange earned by exports was 30.66 million US dollars, an increase of 76.57. The production of silicon in the city's information industry base Hebei Puxing Electronic Technology Co., Ltd., which is mainly engaged in epitaxial wafers, achieved sales revenue of 292 million yuan, an increase of 83.70 year-on-year; Hebei Tonghui Electronic Technology Co., Ltd., which produces chips, achieved sales revenue of 96.55 million yuan, a two-fold increase from January to June.
Machinery for typical gearbox shell body parts, main processing plane and hole system, to ensure that the size of the hole in the process of machining precision and position accuracy, handle the relationship between hole and plane. Should follow the principle of surface before hole, namely first processing box on the datum plane, and then to datum plane positioning processing other plane, then processing hole system. Because of the planar area is large, with its positioning can ensure reliable positioning, clamping and firm, and therefore easy to guarantee machining precision holes. Secondly, cut off the casting surface uneven, create conditions to improve the machining precision of holes, facilitate and adjustment of the knife, is conducive to protect the cutting tool. Processing technology should also follow the principle of separate rough finish machining.
