To make sure the person of handlers is safe, health of industry of lathe of stimulative numerical control develops, logarithm of organization of total bureau of national qualitative check accused lathe product quality to undertake the country is supervised selective examination, selectived examination in all 33 kinds of products that 33 enterprises produce 11 provinces such as Tianjin, Heilongjiang, Liaoning, Zhejiang, Jiangsu, Shaanxi, Shandong, Hunan, Hubei, Henan, Guangdong, municipality directly under the Central Government (do not involve exit product) , sampling percent of pass of product objective quality is 99.8% . This second selective examination the product with partial better quality includes, group of Dalian machine tool is narrow the lathe of CKA6140 numerical control of liability company, the lathe of CAK5085di numerical control of Inc. of Shenyang machine tool, the high speed of SVT125 × 10/5Q-NC numerical control of Inc. of equipment of neat heavy numerical control the center lathe of CK7516 numerical control of Chanzhu vertical lathe and Inc. of machine tool of treasure chicken faithfulness. Selective examination to make clear as a result, successive country is supervised selective examination promoted industry quality awareness rise, strengthened quality management, the product quality of industry of numerical control lathe had very big rise. It is protection of precision of the leakage that selectives examination this, geometry, dormant danger, mechanical overload, dangerous to twine be involved in, extruding and cut dangerous, spacing the 34 projects individual event such as the device, measure that prevent a pine, noise, safe guard is accorded with rate all achieve 100% . Total bureau of national qualitative check will continue to undertake dogging selectiving examination to quality of product of numerical control lathe, make industry of numerical control lathe rectify what the constitution measures a level to rise.
