What factors affected the accuracy of CNC engraving machine is?

Factors affected the accuracy of CNC engraving machine, machine performance is one of, the operation also has a lot to do with people. A wear, tool selection, cutting tool and good cutting tool machining precision caused by the error. 2, processing materials, processing technology, the same error caused by different material machining precision, such as marble and machining aluminum alloy, because the material hardness is different, the machine itself to the limitation of hardware conditions is not only the machining accuracy can't guarantee anything, sometimes even lead to fracture tool, or damage to the machine. Three, the processed parts are firmly, because there will be a moment in the process of carving, if not completely fixed, often there will be a slight position deviation, the feed processing, can affect the processing quality in the end. Four, equipment, power supply, will affect the normal work of the control system, so the device can be installed stable voltage and current. Five, the temperature, abnormal temperature can also make error control system, drive torque performance reach the set value. Six of cutting fluid, oil and dirt, processing environment affect the performance of radiator equipment parts and the performance of the photosensitive element.
