Linear guide rail and carriage is not easy to produce friction heat during operation and is not easy to be deformed by heat, so it is suitable for high-speed movement. They are mainly used in autom...

The function of the linear guide motion is to support and guide the moving parts, and make a reciprocating linear motion in a given direction. According to the nature of friction, linear motion gui...

Some machine tools generate vibration and crawling during movement, and there is often no problem in detecting the mechanical part. No matter how the adjustment is made, the vibration and crawling ...

If the machine tool produces noise and vibration during operation, after checking that there is no problem with the mechanical transmission part, first consider the problem of poor lubrication. Aft...

This problem is generally easy to be overlooked. Due to the long-term reciprocating motion of the machine tool, the screws that fix the flange plate are loosened to create a gap. When checking the ...

For single nut ball screws, the clearance between the screw and nut pairs cannot be adjusted. If it is detected that there is a gap in the screw nut pair. First, check whether the thread arc of the...

Through inspection, if it is confirmed that the fault is not caused by the screw movement. Then it is necessary to consider whether there is a gap between the screw and nut pairs. The detection met...

For example, the dial indicator for measuring the lead screw does not swing when the lead screw rotates forward and reverse, indicating that the lead screw does not move. If the pointer of the dial...

When the reverse error of the CNC machine tool is large, the positioning accuracy is unstable, and the tool marks appear in the quadrant, the first thing to check is whether there is a gap in the s...

The ball screw pair can be lubricated to improve wear resistance and transmission efficiency. Lubricants are divided into two categories: lubricating oils and greases. Lubricating oil, No. 90-180 t...

Inner circulation: The inner circulation adopts the reverser to realize the ball circulation, and there are two types of reverser. Cylindrical convex key reverser, its cylindrical part is embedded ...

The external circulation is that the balls re-enter the circulation between the screw and the nut through the spiral groove or cannula on the outer surface of the nut after the end of the circulati...
