Today we have brought you the important factors of CNC machine tool spindle. The machine tool spindle refers to the axis that drives the workpiece or tool to rotate on the machine tool. The main shaft is usually composed of main shaft, bearings and transmission parts (gears or pulleys). Except for machine tools whose main motion is linear motion, such as planers and broaching machines, most machine tools have spindle components. The movement accuracy and structural rigidity of the spindle components are important factors that determine the machining quality and cutting efficiency. The main indicators to measure the performance of main shaft components are rotation accuracy, stiffness and speed adaptability.
For the modular design of CNC machine tools, simplify the structure of the machine tool, and improve the performance of the machine tool
1. Simplify the structure and promote the modularization of the machine tool structure
The electric spindle can form standardized and serialized products according to the characteristics of use, structure, performance parameters, etc., for the host to choose, thereby promoting the modularization of the machine tool structure.
2. Reduce the cost of machine tools and shorten the development cycle of machine tools
On the one hand, standardized and serialized electric spindle products are easy to form specialized and large-scale production, and can also shorten the machine tool development cycle and adapt to the current rapid and changeable market trend.
3. Improve machine tool performance and reliability
The CNC machine tool adopts the electric spindle structure, because the structure is simplified, the transmission and connection links are reduced, so the reliability of the machine tool is improved; the electric spindle functional components with mature technology, perfect function, excellent performance and reliable quality make the performance of the machine tool more perfect and reliable. Sex can be further improved.
4. Realize the special requirements of some high-end CNC machine tools
Some high-end CNC machine tools, such as parallel motion machine tools, pentahedral machining centers, small hole and super small hole processing machine tools, etc., must use electric spindles to meet the complete functional requirements.
