Detection woodworking engraving machine quality and performance of many factors, including the overall machine configuration, assembly precision, etc. These are mainly embodied in equipment between the vertical axis, flatness, positioning accuracy, repeatability and other parameters. Vertical axis between the main impact of the workpiece dimensional accuracy, XY axis perpendicular to the large degree of typical performance is not equal to the diagonal of a rectangle, Z axis and XY plane perpendicular to a large degree is a typical example of a large flat blade pitch milling plane when uneven surface; flatness main impact plate, the difficulty of leveling the workpiece. After the general assembly debugging to the machine engraving machine milling table to ensure flatness; positioning accuracy error affecting workpiece dimensions, mainly on the accuracy of the screw, the control system of compensation ability, changes in ambient temperature. When the range of processing more than 300 mm, we must consider the size of the workpiece positioning accuracy impact; repeatability main impact multitool processing, multi-step processing. Generally use woodworking engraving machine roller screw drive, no creeping phenomenon, can achieve micro-feed, repeat positioning accuracy mainly depends on the control precision rack drive than the screw drive engraving machine engraving machine precision lower. Only the above-mentioned indicators have reached the requirements to be a qualified woodworking engraving machine, these precision is the mutual influence of mutual restraint, a non-compliance will affect the accuracy of the machine to another.
