How To Choose A Precision Ball Screw

Are you looking for a perfect Ball screw BNT (บอลสกรู BNT;  which is the term in Thai)?  But are you confused about choosing the right one?  Don’t worry.  You will get covered here. The article represents the most important things to consider for choosing ball screws for your operation.

Accuracy Requirements

The ball screws are made using two different methods; such as rolling and grinding. While the rolled screw uses rotating dies to deform metal bars and create a helical thread for the same ball screw, the grind ball screws are made using the method of line cutting in the hardened material that produces a precise thread with tighter tolerance. The rolled linear ball screws are cost-effective, but the ground ball is costly.

Environmental Condition

The ball screws need extra coating protection to help them from damage due to dirt, debris and chemicals. If the coating is not of the right quality, it cannot be easy to protect it from other contaminants. The use of a wiper can prevent the pollutants from entering into the ball screws, and the other one is the use of bellow boots as the covering over the screw. So, you should ensure the ball screw has the proper coating to prevent environmental damage.

The Right Manufacturer

The manufacturer plays a vital role in the selection of suitable Ball screw BNT. The proper manufacturer will guide you in the right way to choose the perfect one for your job. They understand the steel quality, temperature control and overall manufacturing process and guide you according to the requirements. So, you should find a manufacturer who has plenty of experience in the market.

Speed

You should choose your ball screw depending on the speed requirement. You can find two different types of speeds while choosing the ball screw. Let’s have a look over two different kinds of rates:

  • Critical Speed: Critical Speed is the shaft’s natural frequency. The natural frequency refers to the bending and sagging of the screw due to its weight during the operation.
  • Characteristic Speed: The expected speed refers to the force the ball screws during recirculation. While the internal path produces a higher recirculation speed, the external one produces a lower one.

Conclusion

These are all the most important things to consider for choosing a ball screw BNT.   Hopefully,  now you have got your answer. So,  consider the above mentioned things and choose the right ball screw.
