The volume of the engraving spindle is very small, but the structural strength is very high. In order to meet the needs of various long-term industrial production and processing, the structure of the engraving spindle is often specially tempered and optimized. But in the process of use, part of the engraving spindle operation accuracy will also appear to have a decline in the phenomenon, what is the main reason for this phenomenon? Let's discuss this problem together.

(1) the spindle error: carving spindle machining precision requirement is high, material for carving spindle is the center of gravity of the control to be very accurate, when the roundness error and alignment error accumulation to a certain extent, carving spindle axis can deflect, so running accuracy carving spindle is difficult to guarantee.

(2) bearing error: the engraving spindle itself contains many bearing parts, and the connection between it and the engraving spindle motor and other mechanical parts is also completed by many bearing parts. If there is a roundness error in the sliding inner hole of the bearing or the rolling raceway, it will lead to the normal operation of the engraving spindle.

These situations are in fact in the engraving spindle operation process is very likely to appear, we should try to choose those quality product brand when choosing and buying, pay attention to the machine operation state in the process of use, according to the rules of use.
