What are the reasons for the poor surface finish of woodworking engraving machines?

      The quality of the machined surface finish, the material of the material, the choice of tool, the sharpness of the blade, the mechanical rigidity of the machine (whether the machine is shaken during machining), the matching of the parameters of the drive with the control system (including stepper drives and servo drives) ), the parameter adjustment of the control system, etc., in order to process a good effect closely linked to each factor, depending on the specific circumstances to determine the factors caused to solve such problems.
