Main Components of High Speed CNC Milling Machine
Unique functions of the high speed CNC milling machine are tightly connected with various components. Learning the features of these components can help you make a better purchasing decision. The following are main components of the high speed CNC milling machine:
- CNC System: The CNC system is a core component of the entire milling machine. It is used to control the operation process and movement of other components. Based on different programs, the CNC system guides the machine to achieve different machining processes. Common CNC systems include Fanuc, Siemens, and Herdenhain.
- Machine Table: The machine table generally offers high rigidity and load capacity to withstand the workpiece weights and machining force. It is made of high-strength materials to prevent vibration and maintain stability. You can choose a rotary table to achieve simultaneous machining of multiple axes.
- Spindle: Spindle of the high speed CNC milling machine is generally designed with air spindle or electric spindle technology, offering high rigidity and good vibration resistance. Its rotation speed can reach 10,000- 60,000 rpm. The high spindle speed is the base to achieve high-speed cutting.
- Feed System: The feed system is driven by a servo motor, achieving rapid movement of the axes or cutting tools. The feed rate of high speed CNC milling machines is around 30- 60 m/min or faster.
- Tools System: Due to the high-speed cutting function of the milling machine, using the tools with high dynamic balancing performance is important. This can ensure the stability and clamping force of cutting tools. In addition, an automatic tool changes(ATC) system can also help the machine change tools quickly to improve the machining efficiency.
- Cooling System: The high speed CNC milling machine may generate a large amount of heat in the cutting process. If the heat cannot be removed in time, it will affect the workpieces or main components, decreasing the production precision. Using mist cooling, micro-lubrication, or cold air systems can reduce issues caused by thermal deformation and ensure normal operation of the machine.
- Guideway: The high speed CNC milling machine is typically equipped with a linear guideway to achieve high-speed feed, which offers low friction. The linear guideway ensures the straightness and stability of each axis, increasing the machining efficiency.
