Grinded/Ground Ball Screw

Ball screw assembly is consisted of screw, nut and ball. The function is transfer the rotary motion into linear motion or transfer the linear motion into rotary motion. This is further extension and development of slide ball screw. The important significance of development is as same as change of bearing from rolling motion to sliding motion. Because of excellent friction function, ball screw is widely used for all kinds of industrial equipments and precision instrument.

In order to meet the development of CNC machine tools, the company established “large, heavy-load, high-speed, high-precision” of product development direction. In product development, we opened DKFZD end-cap high-speed high-precision ball screw and CMFZD intubation large heavy-load ball screw etc.

At present, the company can produce the ball screw min. dia. of 6mm, min. lead 1mm; max. dia. 245mm; max. single length 10m, max. load more than 100 ton which of various applications; it can provide a mass of 2m P1 grade, 3m P2 grade; 5m P3 grade; 8m P5 grade various ball screws, it’s the professional ball screw manufacturer of all specifications.

High transfer efficiency
Balls with free motion transfer the force and motion between screw and nut in the ball screw assembly. This transfer wise replaces the traditional direct function wise between screw and nut. Therefore the minimum rolling friction takes the place of the sliding friction of traditional ball screw. The transfer efficiency of ball screw will reach more than 90%. The drive torque of transfer unit reduces to 1/3 of sliding screw. This reduces the heat rate largely.
