Low Noise Cnc Ball Screw SFS

Description

Ball screws are used in aircraft and missiles to move manipulate surfaces, especially for electric fly thru wire, and in automobile power steerage to translate rotary motion from an electric motor to axial action of the steerage rack.

They are also used in machine tools, robots and precision assembly equipment. High precision ball screws are used in steppers for semiconductor manufacturing.

Due to the high mechanical efficiency of ball screws, the torque required to function a ball screw is approximately 30% of traditional screw-driven transmission.

Product Description

Flanged Nut Ground Ball Screw SFS1605.Ball screw makes use of balls to roll. The screw shaft has an arc contour, this contour on the shaft in accordance to a sure angle of rise (lead Angle) hovering on the shaft. The ball is designed to roll in the nut, in the arc profile of the screw shaft, so it is rolling friction. Fix one end or both ends of the screw shaft along the axis,drive the ball screw with a motor to rotate, and the nut of the strip ball will go alongside the axis of the ball screw.

Features

1. High transfer efficiency

Balls with free motion in the ball screw assembly transfer the force and motion between screw and nut. This transfer mode replaces the traditional transfer mode that screw shaft and nut effect directly. Therefore the minimum rolling friction takes vicinity of the sliding friction of traditional screw. The transfer efficiency of ball screw will gain higher than 90%. The pressure torque of switch unit reduces to 1/3 of sliding screw. This also greatly reduces the heat release.

2. High positioning accuracy

Ball screw has low warmth release, small temperature increase and with actions of pre-stretch and getting rid of axial clearance in the process, which make ball screw have high positioning accuracy and repeating positioning accuracy. Positioning deviation can be 0.002mm per 300mm travel.

3. Clean and smooth,excellent surface finish

Ball screw has no sticky friction.ISO administration structures make certain strict performance during production and experienced talent staff combing precision computing device and optimized process flow causing super quality smooth ball screw.Each ball screw will go through ultrasonic in the past than assembly.

4. Long service life

Since the strict manage of ball screw groove shapes, surface hardness and material selection, the proper lifestyles of ball screw is much longer.

5. Good synchronization

Due to smooth running, axial clearance removing and consistency in manufacturing, various units of ball screw assembly can drive the equal unit or several identical components to obtain the precise synchronization.
