      Analyze the causes of workpiece instability in small CNC lathes

      issuing time :2019-12-09

      The size instability of workpieces processed by small CNC lathes may be caused by a variety of reasons, and their expressions are also different. In the following, we analyze the causes and corresponding solutions for different phenomena.

      ? ? ? ?1. The workpiece has accurate dimensions and poor surface finish. Causes of the fault: The tool tip is damaged and not sharp; the machine tool resonates and is not placed smoothly; the machine tool has a phenomenon of cymbals; the processing technology is not good. Solution: If the tool is not sharp after being worn or damaged, re-sharpen or pick a better tool to re-set the tool; the machine tool resonance or the placement is not stable, adjust the level, lay the foundation, and stabilize it; the cause of the mechanical hoe is drag The plate guide rail wears fiercely, the screw ball wears or looses, the machine tool should pay attention to maintenance, should clean the iron wire after work, and add lubricating oil in time to reduce the conflict; choose the proper coolant for processing the workpiece, and reach the processing requirements of other processes. In the case, try to choose a higher spindle speed.

      ? ? ? ?2. The cause of the taper size of the workpiece: the level of the machine tool placement is not adjusted, one high and one low, and the placement is not stable; when turning the long axis, the dedication data is relatively hard, and the tool eats the knife deeper, forming the phenomenon of giving up the knife; The tailstock thimble is not concentric with the main shaft. Solution: Use a spirit level to adjust the level of the machine tool, lay a thick foundation, fix the machine tool to improve its resistance; choose a reasonable process and appropriate cutting feed to prevent the tool from being forced to give up the tool; adjust the tailstock on a small CNC lathe.

      ? ? ? ?3. The movement resistance of the machine tool table (or tool post) of the CNC lathe custom manufacturer is too large, which is generally caused by too tight adjustment of the inserts and poor lubrication of the surface of the guide rail of the machine tool. This failure phenomenon generally manifests as irregular changes in part size within a few wires. The inspection can be performed by observing the amount and change of the position deviation of DGN800-804. Usually, the difference is large when the forward and reverse directions are stationary. This kind of failure only needs to readjust the inserts and improve the lubrication of the guide rail.

      ? ? ? ?4. The rolling bearings are worn or improperly adjusted, resulting in excessive movement resistance. This failure phenomenon also usually manifests as irregular changes in size within a few filaments. The inspection can be performed by the position deviation of DGN800-804, the method is the same as above. This kind of trouble only needs to replace the worn bearing and adjust it carefully, and the trouble can be eliminated.
