Analyze the causes of workpiece instability in small CNC lathes
1. The workpiece has accurate dimensions and poor surface finish. Causes of the problem: The tool tip is damaged and not sharp; the machine tool resonates and is not stable; the machine tool has a sting phenomenon; the processing technology is not good. Solution: If the tool is not sharp after being worn or damaged, re-sharpen or select a better tool to re-set the tool; resonance or uneven placement of the machine tool, adjust the level, lay the foundation, and stabilize it; the cause of the mechanical hoe is drag The plate guide rail wears fiercely, and the screw balls wear or become loose. The machine tool should pay attention to maintenance. After work, the wire should be cleaned and lubricating oil should be added in time to reduce conflicts. Select a suitable coolant for the workpiece processing. In the case, try to choose a higher spindle speed.
