The spindles of CNC machine tools are generally driven by DC or AC speed-regulating spindle motors, and high-speed precision bearings are selected to ensure that the spindle has a wide speed range and sufficient rotation accuracy, rigidity and shock resistance. At present, the spindle speed of CNC machine tools has generally reached 5000-10000r/min, and can even be as high as 10000r/min, which is extremely beneficial for processing various small holes and improving the machining accuracy and surface quality of parts.
2. Feed speed
The feed speed of the CNC machine tool is the main factor that affects the quality of parts processing, production efficiency and tool life. It is limited by the calculation speed of the numerical control device, the mobility of the machine tool and the rigidity of the process system. At present, the feed speed of CNC machine tools can reach 100m/min.
3. Itinerary
The stroke size of the coordinate axis x, y, z of the CNC machine tool constitutes the spatial processing range of the CNC machine tool, that is, the size of the processed part. The stroke is an index parameter that directly reflects the processing capacity of the machine tool
