The Important Factors of CNC Machine Tool Spindles in Vertical Machining Centers

Time:2023-11-27 Preview:


The spindle of a machine tool refers to the axis that drives the rotation of the workpiece or tool on the machine tool. Usually composed of spindle components, bearings, and transmission components (gears or pulleys). Except for machine tools such as planers and pullers whose main motion is linear, most machine tools have spindle components. The motion accuracy and structural stiffness of the spindle components are important factors determining machining quality and cutting efficiency. The main indicators for measuring the performance of spindle components are rotational accuracy, stiffness, and speed adaptability.

The role of modular design, simplified machine structure, and improved machine performance in CNC machine tools

a. Simplify structure and promote modular machine tool structure

Electric spindles can form standardized and serialized products based on their usage, structure, performance parameters, and other characteristics for the host to choose from, thereby promoting the modularization of machine tool structures.

b. Reduce machine tool costs 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 development cycle of machine tools, adapting to the current rapidly changing market trends.

c. Improve machine tool performance and reliability

The CNC machine tool with an electric spindle structure has improved its reliability due to its simplified structure and reduced transmission and connection links; The mature technology, complete functions, excellent performance, and reliable quality of the electric spindle functional components make the performance of the machine tool more perfect, and the reliability can be further improved.

d. Special requirements for achieving certain high-end CNC machine tools

Some high-end CNC machine tools, such as parallel motion machine tools, pentahedral machining centers, small hole and ultra small hole machining machines, must use electric spindles to meet complete functional requirements.
