How in the end kind of precision engraving machine , errors can be done to make the product in the end a few wires , in fact we have been in this misunderstanding of accuracy did not come out , engraving machine precision data , we are referring to the organ or dial gauge interferometer with the close under the ruler -type gauge data obtained marble square feet, triangular ruler , etc., this can be called carved accuracy.

      Structure carved now we are clear , generally are six rail (XYZ each 2 ) 3 screw , certain bearings , that we think is certainly the first time : the decision should be carved machine precision guide wire bars and bearings. The answer is absolutely wrong. Accuracy is not decided carved rail screw and bearing , unless it is unscrupulous vendors, using second-hand parts . In fact, the reason is very simple:

        First we look at the parameters of engraving machine (P1313 as an example ) :

       XYZ axis positioning accuracy : 0.010/0.010/0.008mm

       Repeat XYZ axis positioning accuracy : 0.005/0.005/0.005mm

       Currently engraving machine industry screw, rails and bearings are using more sophisticated level , both at the micron level accuracy , so this error can be ignored , the key lies in whether the various precision components installed in place of traditional linear guide is installed using scraping , mat copper , etc., which fitter skill requirements are very high and unstable . Easily lead to uneven , vertical , not high .
