(1) Periodic inspection of the support bearings of the machine tool Periodically check the connection between the ball screw support and the machine tool bed for looseness and whether the support bearing is damaged. If there is any problem above, tighten loose parts and replace support bearings in time.
(2) Lubrication and sealing of the ball screws of the machine tool The ball screw pair of the machine tool can use lubricant to improve the wear resistance and transmission efficiency. Lubricants can be divided into two major categories of lubricants and greases. The machine tool oil is general oil or turbine oil No. 90-180 or No. 140 spindle oil. Machine tool grease can use lithium grease. Grease is generally added to the housing space of the threaded raceways and mounting nuts, while lubricant is injected into the nut space through the oil holes in the housing.
