Ball screw manufacturer Introduction The ball screw is one of the most important components in a CNC lathe, directly affecting the functionality of the machine. Today, we live in an era that places great emphasis on efficiency, and thus the demands on CNC lathes are quite high. To ensure that a CNC lathe performs even better, it needs a ball screw with superior performance. So, how can we enhance the performance of a ball screw?

　　1. Improve the structure to enhance the fluidity of ball sports.

　　Improve the switching machinery and equipment of the ball circulation system, optimize the curve parameters of the return chute, select three-dimensional-shaped ball tubes and return devices, and ensure that the steel balls are accurately introduced into the nut body along the chamfered edges of the threads—thus aligning the balls’ motion path to intersect rather than cross with the dovetail guide rails. In this way, impact damage and noise can be significantly reduced.

　　2. Select specialized skills with strong cooling capabilities for hollow structures.

　　 The ball screw manufacturer stated. During operation, CNC lathes can experience sustained high temperatures due to frictional contradictions, leading to thermal expansion of the ball screw. This directly affects the dimensional accuracy of high-speed CNC lathes. Selecting hollow, high-efficiency cooling involves introducing temperature-controlled cutting fluid into the hollow bore of the ball screw to forcibly cool the ball screw and maintain a stable ambient temperature within the ball screw assembly. This is also a practical method for enhancing both the performance and operational accuracy of the ball screw.

　　3. Adjust the lead screw speed, pitch, and number of threads appropriately.

　　At this stage, common combinations of outer diameter and pitch for large-pitch ball screws include 40×20 and 50×25. The feed rate can reach over 60 m/min. To enhance the bending stiffness and load-carrying capacity of ball screws, large-pitch ball screws typically employ multi-start threads, thereby increasing the number of ball bearings that can effectively bear the load.

　　 The ball screw manufacturer stated. Ball screws are becoming increasingly widespread across various industries. However, ball screws often encounter numerous challenges during operation. To address the issue of vibrations and smoothness problems that many people are curious about when using ball screws, the editor would like to provide an analysis below. The following are the most common reasons for the smoothness issues experienced with ball screws:

　　I. Challenges in the Processing and Manufacturing of Ball Screw Rods

　　1. The surface of the ball screw or the nut’s ball track is not smooth.

　　2. The concentricity of the ball, nut, or nut exceeds the tolerance range.

　　3. The pitch deviation of ball screws or bolts, or the round diameter, exceeds the tolerance range.

　　4. The inverter assembly is improperly configured.

　　II. Beyond the Itinerary

　　The primary causes of scheduling issues often lie in equipment settings, common malfunctions of limit switches, or impacts. To prevent further damage to the cue, it must be re-serviced and maintained by the manufacturer before being reassembled.

　　III. Return pipe damage

　　 The ball screw manufacturer stated. The return pipe may suffer significant impact during installation, potentially leading to dents and the same issues mentioned above.

　　IV. Axial Force

　　If the nut housing differs from the bearing with housing, it often results in axial load. When the axial force is excessive, it can also cause the lead screw to bend or even break.

　　5. Damage to the ball screw caused during transportation and the shipping process.
