Ball screws are used in aircraft and missiles to move control surfaces, especially for electric fly by wire, and in automobile power steering to translate rotary motion from an electric motor
to axial motion of the steering rack. Because it's small friction drag,They are also used in
machine tools, robots and precision assembly equipment. High precision ball screws are used in steppers for semiconductor manufacturing.
Features: 1.A small friction loss, high transmission efficiency
There are a lot of balls rolling movement between the screw shaft and ball screw screw nut, they are able to get a higher efficiency of movement. Helpful in saving.
2.High-precision
Ball screw was manufactured by the world's highest level mechanical equipment, especially in the grinding, assembly, inspection of the process plant environment, temperature and humidity were strictly controlled, because of the sound quality management system so that the accuracy can be fully guaranteed.
3.High speed feed and Micro-feed may
Ball screw used the ball movement, so the starting torque is very small, It's doesn't appear as a sliding motion creeping phenomenon , can ensure accurate micro-feed.
4.Axial stiffness high
Ball screw can be adding preloading, The axial clearance can be achieve negative due to the pre-pressure , then get a higher rigidity.
5.Due to their high efficiency,precision ball screw assemblies are in principle not self-locking.
