Ball screw by a ball screw, and ball roller nut composition, may be a rotary motion into linear motion screw manufacturers, or the linear motion into a rotary motion of the member. Ball screw drive with high efficiency, long life, smooth movement, synchronization without crawling, no reverse backlash, excellent friction characteristics, advantages and strong adaptability to the environment is the key to drive all types of CNC machine tools and machinery and electronic products sub and the positioning element screw production, has been widely used in various areas of transmission. At present, the ball screw manufacturing factory, process route are some differences in the number of screw machining, product quality and there are many problems. General manufacturing process steps: cutting (the vast majority of material is GCr15) - straightening - car cylindrical - IF quenching - tempering - repair research center hole - cylindrical grinding - Thread grinding mill cut screw thread - milling keyways or square body - fitter process - to stress - semi-precision grinding screw thread grinding thread - again stress - grinding center hole - precision cylindrical grinding - Precision Thread mill grinding screw thread - ends incomplete inverted tooth 1/4 turn - thread grinding and top 45 ° chamfer thread processing. Ball (ball screw) life expectancy must reference design and other quality and process several safety factors, but the most important to the dynamic load (C) as the basis. The basic dynamic load factor for the - tooth type accuracy, material properties and surface hardness. High quality ball screw (ball screw), must reach the statistical life B grade (ie 90% of the screw are designed to achieve life), 50% more than the life of a ball screw design lifetime value of 2 to 4 times.
