Dalian of rejected product of birth of eligible machine tool flies amount to enterprise of Hunan harmful pain

Sticking ” certificate of approval ” what machine tool production goes out is unqualified product completely, 460 thousand yuan of payment for goods in one’s hand hind, refus does not admit the machine tool has quality problem, however with ” operation error ” wait for reason general responsibility all shirk gives the buying party, dalian flies the inferior machine tool that amounts to production of mechanical production limited company is killed sufferred from Hunan double horse electric limited company. Came in May 2010 during August, hunan double horse is electric limited company (company of double horse of the following abbreviation) fly from Dalian early or late amount to mechanical production limited company (the following abbreviation flies amount to a company) purchased lathe of 3 Chan Zhuli type, among them CX5110 two (number is D1008101, D1008102) respectively, CX5112 (number D1005056) , goods is worth add up to 460 thousand yuan. However, double horse company discovered during facilities tries an operation machine tool precision forbids to wait for quality problem, machine the product that come out to short of quality asks and all can discard as useless only, because this is serious,manage what affected a company normally, caused huge loss to the company. Detect via double horse company discovery, actual precision does not accord with the machine tool fly the tolerance on the product certificate of approval that amounts to a company to offer, and error is bigger. The lathe of odd column vertical that is D1008101 with number is exemple, fly the place of certificate of approval that amounts to a company is shown ” workbench end panel is jumpy ” allow difference is ” 0.05mm is inside 1000mm diameter ” , fly the actual measurement value that amounts to a company is 0.03mm, but value of actual measurement of double horse company is 0.08mm. The immediate consequence that machine tool precision forbids to bring about machines the product that come out to not agree with namely add up to norms to ask, cause ” round, square ” case, this is an immense labor to rigid production business. As we have learned, double horse company ever forbade to wait with respect to machine tool precision in June last year problem and fly amounted to a company to undertake for many times negotiation, although the other side ever sent a person 3 times to come round to maintain, but inextricability from beginning to end problem, equipment still cannot be used normally up to now. Subsequently, fly amount to a company to handle the reason shirk responsibility such as error with double horse company unexpectedly, refus does not respond to all requirements of double horse company. But under, double horse company pledges to Xiangtan city inspect bureau is complained. Xiangtan city pledges inspect bureau stems from service company, maintain the position of business rights and interests, the requirement flies before amounting to a company to send a person, will handle relevant matters concerned, danfei amounts to a company still the attitude is aloof. This year on April 1, xiangtan city pledges inspect bureau pledges to Hunan Province inspect bureau applies for product quality appraisal. Suffer Hunan Province to pledge inspect bureau is appointed, the expert has collate test at going to the spot on April 19 related organization of institute of Hunan Province quality inspection. The expert is undertaking detecting. Basis of personnel of spot survey produce the expected result ” vertical lathe examines conditional precision examines the 1st part: Chan Zhu and lathe of double column vertical ” (GB/T 23582.1-2009) is right the project of place designation of certificate of approval of product of 3 machine tools undertook precision examine, according to ” the metal is cut cut a machine tool current technology condition ” (GB/T 9061-2006) , ” the metal is cut cut machine tool casting pig technical condition ” (JB/T 3997-94) level is right hardness of cast of beam of 3 machine tools undertook examining, examine eventuate does not accord with national level to ask. Meanwhile, crossbeam is perpendicular and mobile shift of the verticality of the face, vertical to workbench tool carrier is opposite ram of the parallelism of workbench face, vertical tool carrier moves the parallelism of pair of workbench axis of rotation (or goods of vertical tool carrier moves really the verticality of pair of workbench faces) wait for a project. Additional, value of hardness of surface of cast of beam of 3 machine tools all also does not accord with GB/T 9061-2006, JB/T 3997-94 the requirement of relevant provision. The expert discovers in detect, fly amount to a company charge for the making of sth. of product of these 3 machine tools is very coarse, and the industry standard of designation of the place on certificate of approval all far the requirement under national level. After product quality survey report comes out, bureau of Xiangtan city qualitative inspect gives at will reporting the result is sent with express means on May 7 fly amount to a company, the requirement sends a person to come round to assist processing, danfei amounts to a company still pay no attention to, end before distributing news dispatches, this company still did not manage with double Ma Gong or bureau of Xiangtan city qualitative inspect gets in touch. As we have learned, dalian flies amounting to mechanical production limited company is business of mainstay of stress of production industry of Dalian city machinery, of production (number is shown, numerical control) lathe of Chan Zhu, Shuang Zhuli type, sell each district of past whole nation not only and sell as far as to the world each district such as the United States, Russia, Italy. Normally for, the machine mass that this company produces is to have assure, fly however 3 machine tools that amount to a company to sell double Ma Gong manages all appeared same quality question, and be tagged on product certificate of approval industry standard actually under national level, this lets a person unimaginably queer. This kind reduces product standard to produce the method of responsibility of shirk of problem of quality of inferior product, occurrence product, let a person generate suspicion to the character of this enterprise indeed.
