There are many factors to measure the performance of woodworking cnc router, not only the overall configuration of the machine, but also the assembly precision of the machine. These are mainly reflected in the verticality, flatness, positioning accuracy, repeat positioning accuracy and other parameters of the equipment. . The perpendicularity between the axes mainly affects the dimensional accuracy of the workpiece. The typical performance of the XY axis with a large verticality is that the diagonal of the rectangle is not equal. The typical verticality of the Z-axis and the XY plane is that the flat-blade milling plane is used. When the surface is not flat; the flatness mainly affects the difficulty of leveling the sheet and the workpiece. So how do you judge the quality of the woodworking cnc router? The following is for everyone's analysis:
After the assembly and debugging of the machine is completed, the cnc router table surface should be flattened to ensure the flatness; the positioning accuracy affects the dimensional error of the workpiece, which is mainly determined by the precision of the lead screw, the compensation ability of the control system, and the change of the ambient temperature. When the machining range exceeds 300 mm, the influence of the positioning accuracy on the workpiece size must be considered; the repeated positioning accuracy mainly affects multi-tool machining and multi-step machining. The cnc router is generally driven by a roller screw, and there is no creeping phenomenon, so micro feed can be achieved. The repeat positioning accuracy is mainly determined by the control accuracy.
The cnc router of the rack drive is lower in accuracy than the cnc router of the lead screw drive. Only the above mentioned indicators can meet the requirements to be a qualified woodworking cnc router. These precisions are mutually dependent on each other, and one failure will affect another precision of the machine. If the machine is not up to standard, then the processed things are definitely less accurate.
