Advantages and disadvantages of linear three-axis linear motor drive machining center
The appearance of the linear motor makes the servo motor + rolling screw drive device very embarrassing, because the linear motor can replace the servo motor + rolling screw to drive the linear three-axis. Linear motors are generally used in high-speed machining centers. Generally, CNC machines rarely use linear motors to drive linear three-axis, because the current linear motor-driven three-axis technology is mature enough. Next, let Xiaobian introduce the advantages and disadvantages of linear motor drive linear three-axis.
Servo motor + rolling screw drive linear motor drive
The advantages of linear motor drive machining center linear three-axis
The linear motor drives the linear three-axis with the advantages of high speed, high efficiency and excellent rigidity. The linear motor drives the linear three-axis speed 2-3 times faster than the servo motor + rolling screw drive linear three-axis speed. The servo motor + rolling screw drive linear three-axis feed speed is generally 48m/min, while the linear motor The feed speed of the drive linear three-axis is 86m/min; since the servo motor + rolling screw is the transmission type, the rigidity is not as good as the linear motor.
The disadvantage of linear motor drive machining center linear three-axis
Since the current linear motor drive linear three-axis technology is not mature, linear motors still have many shortcomings, such as high cost, large heat generation, and poor transmission stability. Linear motors are very expensive to manufacture and are therefore expensive to sell. Due to the high speed of the linear motor, a certain amount of heat is generated during the high-speed movement. The faster the speed of the linear motor, the higher the heat generated, so the linear motor drive linear axis device must be equipped with a cooling system.
