Numerical control line mechanical accuracy

Generally in the mold processing in wire-cutting processing for final stage, so for machining accuracy is demanding, if the mechanical precision machine tool is bad, will directly influence the processing quality products and tool, eventually leading to lose user, loss of market, so the wedm selection, how to determine the mechanical precision and structure, actor is very important.
General new wedm accuracy easy judgment, because have gb GB7926-2005 and related machine precision general standard, so that in the new machine commissioning acceptance when can know qualified or not. However, the most important is to machine tool accuracy stable judgment, for machine accuracy stable quality only in the machine after a certain period of use will reflect, and the national standard cannot carry on the strict quantitatively control and therefore can only be the users themselves in the model selection of machine tools and structure conducted detail understanding, must not hearsay, slant listen to appreciate some groundless rumour, lest disturb your judgement.
