O'tmishda uzoq vaqt davomida, G'arb davlatlarining embargo cheklovlari tufayli, mening mamlakatimga xorijiy o'ta aniqlikdagi dastgoh asboblarini import qilish jiddiy cheklangan edi. Biroq, 1998 yilda mening mamlakatimning CNC o'ta nozik dastgohi muvaffaqiyatli ishlab chiqilganda, G'arb davlatlari mening mamlakatimga nisbatan taqiqni darhol olib tashladilar va mening mamlakatim hozirda bir qator o'ta nozik dastgoh asboblarini import qildi.
my country's Beijing-Machine Tool Research Institute, Aviation Precision-Mechanical Research Institute, Harbin Institute of Technology and other units have now been able to produce several kinds of ultra-precision CNC diamond machine tools, such as the ultra-precision lathe with a processing diameter of 800mm developed by the Beijing Machine Tool Research Institute and the Harbin Institute of Technology. The two machine tools have two-coordinate precision numerical control system and two-coordinate laser online measurement system, which can process aspheric surfaces of revolution; and Harbin Institute of Technology has developed an ultra-precision milling machine for processing KDP crystal large planes. KDP crystals can be used for optical frequency doubling and are important components in high-power laser systems. It must be admitted that in terms of ultra-precision machine tool technology, there is still a considerable gap between us and foreign advanced level, and the quality level of domestic ultra-precision machine tools needs to be further improved.
Keng ko'lamli o'ta nozik dastgohlar nuqtai nazaridan, hozirgi vaqtda Qo'shma Shtatlar, Buyuk Britaniya, Rossiya va boshqa mamlakatlar o'zlari tomonidan ishlab chiqilgan keng ko'lamli o'ta nozik dastgohlarga ega. Biroq, mening mamlakatimda katta hajmdagi o'ta nozik dastgohlar mavjud emasligi sababli, katta diametrli kavisli nometall va boshqa katta hajmdagi o'ta nozik qismlarni qayta ishlash mumkin emas. Katta o'ta aniq qismlarni eksport qilishda qat'iy cheklovlar mavjud bo'lib, bu mening mamlakatimizning milliy mudofaa sohasidagi ilg'or texnologiyalarini rivojlantirishga jiddiy ta'sir qiladi. Hozirda mamlakatimizda diametri 1 m dan ortiq vertikal o‘ta aniq dastgohlar ishlab chiqarish jadal rivojlanmoqda.
Ko'p funktsiyali va yuqori samarali maxsus maqsadli o'ta aniqlikdagi dastgohlar nuqtai nazaridan, mening mamlakatim hali ham bo'sh.
