    For CNC lathes, screw bearings are very important components. As we all know, bearings are one of the more precise equipment components in machine equipment. Therefore, if they have a fault, they usually need to be replaced. Maintenance generally cannot solve the problem, and certain steps must be installed during replacement. Today, our CNC lathe manufacturer will explain the top ten precautions for replacing screw bearings.
    1: Can the CNC lathe shaft screw pressure bearing be replaced with ordinary bearings? Answer: It is necessary to choose according to the original structure. Pressure bearings are acceptable, but corner bearings are not.
    2: Video on how to install the ball screw of the CNC lathe slide plate<br/>Answer: The ball screw nut pair is only used to bear axial loads, and radial forces and bending moments can add surface contact stress and other loads to the ball screw nut pair, which may cause permanent damage to the screw. Proper installation is a prerequisite for effective maintenance. Therefore, when installing the ball screw nut pair onto the machine tool, the following points should be noted: ① The axis of the screw must be aligned with the matching guide rail.
    3: How to repair the loose X-axis screw of a CNC lathe?
    How to replace the screw rod bearing on a CNC lathe? Answer: Is the screw nut loose or is the bearing loose? If the nut is loose, you can adjust the preload or replace the ball or screw. If the bearing is loose, adjust the locking nut of the back bearing.
4: What are some methods for dismantling the spindle bearings of CNC machine tools for maintenance personnel?
How to replace the screw bearing of a CNC lathe Answer: 1. Spindle part 1. Spindle motor. Most CNC machine tools use variable frequency speed control motors. Variable frequency speed regulating motors have relatively hard mechanical characteristics and good stability; No slip loss, high efficiency; Simple wiring, easy control, and low price; Capable of efficient and smooth speed regulation, with high speed, high power, rapid and reliable speed changes; Capable of continuously variable transmission and other features.
     5: How to assemble CNC lathes and X-direction ball screw angular contact bearings?
How to replace the screw bearings on a CNC lathe? Answer: This is a highly difficult technical task! If the X-direction screw cannot be installed, replace it. Anyway, the price is not high! Good luck to the poster.
6: Installation method of ball screw nut pair for CNC lathe
Answer: Installation method of ball screw nut pair Ball screw nut pair is only used to bear axial loads. Radial forces and bending moments may cause additional surface contact stress and other loads on the ball screw nut pair, which may cause permanent damage to the screw.
7: The gap between the ball screw and the nut of a CNC lathe is too large. How to replace the ball screw
How to replace the screw bearings on a CNC lathe Answer: Clean the ball screw nuts and balls thoroughly. Put the plastic ball stopper (ball reverser) back into the nut. When installing the ball stopper, pay attention to the smooth connection between the ball inlet and outlet of the stopper and the spiral groove. Apply grease inside the nut. Place the ball into the spiral groove. Note that not all spiral grooves are filled, and a bead stopper is a circular ring.
8: How to calibrate the spindle side busbar of 980TD CNC lathe? X-direction ball screw shaft
Answer: The calibration of the spindle side busbar is not related to the system. It is difficult to describe the disassembly of the main spindle side busbar and screw rod in pure text. Please consult a mechanic.
9: How to replace the steel ball of the x screw of the CNC lathe?
Answer: Replacing the steel ball can only be used temporarily, but the accuracy may be slightly worse. It is best to replace the lead screw with a new one! The X-axis screw is not expensive.
10: How to replace bearings on a CNC lathe
Answer: I just replaced a pair of angular contact bearings for the X-axis last month. 1. Remove the X-axis motor, 2. Remove the X-axis strip, and 4. Remove the screws from the middle position of the middle support plate. Pull out the middle pin. The middle support plate can be pushed to remove the synchronous belt pulley, which can be replaced by knocking it out from the X direction and installed in about 3 hours.
The above are the top ten precautions for replacing screw bearings shared by CNC lathe manufacturers, hoping to be helpful when replacing screw bearings in CNC lathes in the future.
