How many money a CNC lathe
Level of CNC lathes, to see it repeated positioning accuracy, repositioning precision of the numerical control lathe if can areach 0.005 mm (ISO standards. And statistics), is the high precision machine tool, in the 0.005 mm (ISO standards. And statistics), of the following is the ultra precision machine tools, high-precision machine tools, to have the best bearing, screw.When it comes to the "precision" of the machine, be sure to clarify the definition and calculation method of standards and indicators.Japanese machine tool manufacturers calibration "accuracy", usually adopt JISB6201 JISB6336 or JISB6338 standards.JISB6201 is commonly used in general machine tools and common nc machine tools, JISB6336 generally used for machining center, JISB6338 is commonly used for vertical machining center.All three the same as the basic standard in the defined position accuracy, this paper only to JIS B6336 as an example, because on the one hand, the standard is relatively new, relative to other two kinds of standards on the other hand, it wants to use a little accurate.Machine tool manufacturers of Europe, especially Germany, generally USES the VDI/DGQ3441 standards.American Machine Tool manufacturers usually adopt NMTBA (National Machine Tool Builder 's Assn) standard (the standard is the result of a study by the American association for the Machine Tool manufacturing, enacted in 1968, after the change).Mentioned above, these standards are associated with ISO standards.Machining center processing dimensional accuracy, form and position accuracy of typical parts, for example contrast level both at home and abroad, and domestic roughly 0.008 ~ 0.010 mm, and the international advanced level of 0.002 ~ 0.003 mm. The machine tool manufacturing industry development in our country, though there are ups and downs, but for numerical control technology and numerical control machine tool has been given greater attention, has strong market competitiveness.But in terms of medium and high-grade CNC machine tool, and some foreign advanced products and technology development, there is still a large gap, most technology tracking stage. Ultra precision machining is refers to the size and location accuracy is 0.01 ~ 0.3 microns, shape and contour accuracy of 0.003 ~ 0.003 microns, the surface roughness of steel Ra 0.05 microns or less, copper pieces of Ra 0.01 microns or less.The domestic development of ultra-precision CNC lathe, CNC milling machine has been put into production use.
