CNC Vertical Machine Center Processing Accuracy Error And Countermeasures Three

Nov 07, 2019

cnc vertical machine center

The machining accuracy of CNC vertical machine center is mainly as follows: the surface roughness of the inner hole is high, the inner hole of the hinge is not round, the position of the hinged hole is out of precision, and the inner surface of the hole has obvious facet and reaming. The center line of the rear hole is not straight, the aperture is enlarged, the aperture is reduced, and the like.


The following ALLES CNC takes you to understand the reasons for the machining accuracy of CNC vertical machine center and the third method of processing - the machining aperture is increased.

Increased processing aperture


Reasons for this: CNC vertical machine center may increase the aperture diameter during processing. The reamer outer diameter size may be too large or the reamer edge may have burrs, the cutting speed is too high, the feed rate is improper, or the machining allowance is too large. The main angle of the reamer is too large, the reamer is bent, the built-up edge of the reamer is adhered, the slanting edge of the reamer is too poor, the cutting fluid is not properly selected, and the problem of the CNC machine itself may be The above problems may occur if the spindle is bent or the spindle bearing is too loose or damaged.


Remedy: According to the actual inspection situation, the following measures can be taken: according to the specific circumstances, reduce the outer diameter of the reamer, reduce the cutting speed, adjust the feed amount or reduce the machining allowance, reduce the lead angle, straighten or scrap Bending unusable reamer, selecting cutting fluid with better cooling performance, adjusting or replacing the spindle bearing, or replacing the entire spindle.
