Common Faults And Solutions Of Spindle Of Mini Cnc Lathe

Common faults and solutions of spindle of mini CNC lathe:

(1) The spindle runs over speed for a long time and generates heat. Solution: adjust the bearing clearance, appropriately reduce the spindle speed (which shall not exceed the design maximum speed of the machine tool), and apply high-speed grease on the bearing.

(2) The main shaft bearing clearance is too tight and generates heat. Solution: refer to section 4 to adjust the bearing clearance of the main shaft.

(3) The main shaft bearing is rusted, worn and heated, and parts of the main shaft may be worn or rusted after long-term fatigue use or in humid environment; Long storage time without use will also cause bearing rust. Solution: clean the bearing, adjust the grease or replace the bearing.
