Ball screw is general technical requirements which need to make? 1 mainly in the following aspects: geometric precision CNC lathes and ball screw, including travel deviation test, beating examination, positional tolerance test. Which include targeted travel itinerary deviation tolerance, effective stroke compensation value, the amount of variation in the effective stroke, stroke deviation within one revolution. Beat deviation including thread diameter of the axis radial runout agent on the silver ball screw grinding, journal runout, axial runout shoulder grinding agent TBI ball screw, a nut preload mounting end face axial runout. 2: materials and heat treatment. 3: preload, pre-tensioning load size. Ball screw by professional manufacturers, such as no special requirements, as long given its level of accuracy and geometry can be. To achieve its high performance ball screw, China's production of high-precision ball screw machine use on the drive ratio has been greatly improved. Currently the machine uses a ball screw, a lower domestic prices, there are high precision imported products in Japan and Europe. The use of imported products are often those of processing speed, accuracy, longevity and stability with high requirements of the machine. CNC lathes ball screw, Korea and Taiwan transmission machinery, ball screw provided by the Dongguan City, Transmission Machinery Co., Korea and Taiwan.
