The main axis of the machine tool refers to the rotation of the workpiece or knife of the tools on the machine. The main shaft component is usually composed of the spindle, bearings and transmission parts (gears or wheels). Except for the main movements such as planes and beds, most of the machine tools, most machine tools have main parts. The movement accuracy and structural stiffness of the spindle component is an important factor that determines the quality and cutting efficiency of processing. The indicators to measure the performance of the spindle component are mainly rotating accuracy, stiffness and speed adaptability.

The role of the modular design of CNC machine tools, simplifying machine tool structure, and improving the performance of machine tools

a. Simplify the structure and promote the modularization of the machine tool structure

  The electrical main shaft can form standardized and series -based products based on the characteristics of use, structure, performance parameters, and for hosting, thereby promoting the modularity of the machine tool structure.

b. Reduce the cost of machine tools and shorten the development cycle of machine tools

  On the one hand, standardized and series of electrical main shaft products are easy to form specialized and large -scale production, and can also shorten the development cycle of machine tools to adapt to the current rapid and changeable market trends.

c. Improve the performance of machine tools and improve reliability

  CNC machine tools with electrical spindle structures, due to the simplification of structure, reduced transmission and connection links, therefore improves the reliability of machine tools; electrical main axis functional components that are mature, well -functional, excellent in performance, and reliable quality make the performance of the machine tool more complete, reliable reliability Sex is further improved.

d. Realize the special requirements of certain high -end CNC machine tools

  Some high -end CNC machine tools, such as parallel motivation tools, five -facain processing centers, small holes and ultra -small hole machining machine tools, etc., the main shaft must be used to meet the complete functional requirements.
