1, the spindle box is overheated

(1) The spindle is overheated for a long time and generates heat. Solution: Adjust the bearing clearance, properly reduce the spindle speed (do not exceed the maximum speed of the machine design of this model), high-speed grease on the bearing.
(2) The spindle bearing clearance is too tight and generates heat. Solution: Refer to the fourth section to adjust the bearing clearance of the spindle.
(3) The spindle bearing is rusted and worn and generates heat. If it is used for a long time or in a humid environment, the spindle may be worn or rusted. If the storage time is too long, it may cause the bearing to rust. Solution: Clean the bearings to adjust the grease or replace the bearings.

2, machine bed deformation

Improper installation of the machine tool causes distortion of the machine bed and can cause the large carriage to move too tight or get stuck. Solution: Loosen the anchor bolts to restore and reinstall them to ensure the level of the foot and the work surface (this solution is the solution for the new machine when it is installed).

3, guide rail chip

Loosen the large pallet guard screws and remove the large pallet guards and guard pads. Then loosen the large pallet pressure plate screws, remove the large pallet pressure plate, and wash the carriage and guide rail with kerosene. It takes a while to replace the size of the pad guard pad (wool felt) to prevent iron filings from entering.
