The difference between belt drive and direct drive of VMC
According to different transmission parts, CNC vertical machine center pindles are divided into four types: gear drive spindles, belt drive spindles, direct drive spindles and electric spindles. These four types of spindles are used in different situations according to their own characteristics.
(1)Gear-driven spindle: CNC vertical machine center spindle speed is generally 6000r/min, which is more suitable for heavy cutting occasions;
(2)Belt drive spindle (synchronous belt drive spindle): CNC milling machine spindle is mainly driven by belt teeth, and its spindle speed is generally 8000r/min. This type of spindle is more suitable for heavy cutting occasions;
(3)Direct-connected drive spindle: It is driven by a motor connected to the spindle through a shaft coupling. vertical cnc milling machine speed of this type of spindle is generally 12000-18000r/min. The direct-connected spindle is not suitable for heavy cutting and is only suitable for processing with a small amount of cutting tool. The workpiece is suitable for finishing occasions;
(4)Electric spindle: 3 axis vertical machine center spindle is integrated with the motor. The motor is the spindle, and the spindle is the motor. The motor and the spindle are combined into one. The spindle is the fastest in the world, and its speed is above 18000r/min. , For example, the electric spindle adopts air static pressure bearing and magnetic suspension bearing, and its speed can reach up to 100000r/min. This kind of spindle is generally used for finishing occasions and is not suitable for heavy cutting occasions.
