Ball screw processing technology requirements which
therefore, according to JB2886-81 provisions, screw and pitch accuracy, according to the use of requirements are divided into six levels: 4,5,6,7,8,9 (accuracy in turn lower).
In the national standard GB785-65, the ordinary trapezoidal thread accuracy is divided by the diameter tolerance. There are five basic parameters: the outer diameter d, the diameter d1, the diameter d2, the pitch t and the tooth half angle α / 2. As the screw to pass accurate movement,
diameter d ratio is very large, generally 20 ~ 50, poor rigidity. Complex structure, there is a high thread surface requirements, as well as ladder, groove, etc., so the process is prone to deformation.
There is a component on the machine that is made of long, long metal rods. Above the surface is very high finish, and some also with a thread. Generally in the machine above the thread, called the screw. Choose a variety of high-quality screw look titanium Hao,
