The method of improving the performance of ball screw

　The more important part of the machine tool is the ball screw, which directly affects the function of the machine tool. So how to improve step ball screw function?

Now is a pay attention to a rate of the era, machine tools have higher requirements. If you want better function of machine tool, you need better function of ball screw. Today, we will briefly introduce the method:

One, properly increase the screw speed, lead and thread number

Now the matching of nominal diameter and lead of large lead ball screw is commonly used: 40* 20,50 *25, etc., and the feed speed can reach more than 60m/min. In order to improve the stiffness and bearing capacity of the ball screw, double-headed threads are generally selected for the large lead ball screw to improve the number of useful bearing circles of the ball.

Second, improve the structure and improve the smoothness of ball movement

Improve the ball circulation reverse equipment, optimize the curve parameters of the ball groove, select three-dimensional modeling ball pipe and ball return, truly achieve the ball into the nut along the lead Angle of the inner thread, so that the direction of ball movement is tangent to the raceway instead of intersecting. This reduces impact losses and noise.

Three, the selection of ball screw support bearings

The selection of ball screw bearings is very important, it directly affects the life and function of engraving machines and other machine equipment or spindle.

Four, choose "hollow strong cold" skills

High speed ball screw in operation because of conflict occurs high temperature, the formation of screw thermal deformation, directly affect the machining accuracy of high speed machine tools. The selection of "hollow strong cooling" skill, is the constant temperature cutting fluid through the hole of the hollow screw, forced cooling of the ball screw, keep the stability of the ball temperature. This method is a useful way to improve the high-speed function and operation accuracy of large ball screws.
