With the improvement of the speed of the machine, the guide rail is also used to scroll through the conversion by the slide. In China, due to the low speed machine tool and manufacturing costs on a sliding rail use is also the majority, but the use of ball roller guide rails and the number of machines in the rapid rise. Because rolling guide has a high-speed, long life, plus the advantages of pre-press, ease of installation, etc., with the improvement of performance and CNC machine tools required to improve rail rolling use ratio is an inevitable trend. Ball ball screw drive system is an advantage to the media as the rolling ball rolling screw drive system. To drive into the form, the rotary motion into linear motion; the linear motion into rotary motion of the two. Ball has the following advantages: First, the smooth movement of the ball screw drive system for point contact rolling motion, work, small friction, high sensitivity, without trembling at startup, low speed without creeping phenomenon, so you can precisely control the micro to. Second, high transmission efficiency ball screw drive system transmission efficiency up to 90% to 98%, for the traditional sliding screw system 2 to 4 times, such as cold rolled ball screw, they are able to get a larger less torque thrust, also the rotary motion into linear motion by (movement reversible). Third, high-precision ball screw drive system sports a smaller temperature rise, and tightening the screw to eliminate axial clearance and pre-stretched to compensate for thermal elongation, so you can get high positioning accuracy and repeatability of positioning accuracy .
