The vertical degree between the axes of CNC cutting machine affects the dimensional accuracy of the workpiece first, Z axis and XY plane straightness is the typical performance of large spacing milling plane with flat edge knife, the surface is uneven, XY axis straightness is the typical performance of the rectangular diagonal is not equal.

The positioning accuracy of NC cutting machine affects the size error of the workpiece, which mainly depends on the precision of the lead screw, the compensation ability of the control system and the change of the environmental temperature. When the machining range exceeds 300 mm, it is necessary to consider the effect of positioning accuracy on workpiece size.

Numerical control cutting machine, repeated positioning accuracy of the primary impact of multi-tool processing, multi-process processing. Engraving machine using roller screw drive, no creeping phenomenon, can achieve micro feed. The repeated positioning accuracy is primarily determined by the control accuracy, which is generally 2 control resolutions.

CNC cutting machine comply with the development trend to replace manual operation:

Because the transformation project is carried out under the existing conditions of the factory workshop, compared with the new project, it will be restricted by many objective conditions. Therefore, it is necessary to design the engineering project system:

1. Personalization. Meet the actual factory, can fully meet the needs of automatic production, solve the key problems.

2. Economy. Focusing on the cost performance of the project, under the premise of satisfying the requirements of automatic production, simple, not luxury, as little money as possible, save the cost of transformation.

3. Maximize. With the same transformation cost, we can try our best to improve the degree and level of automation, with less or no labor, and improve the output.
