Advantages and disadvantages of linear three-axis linear motor driven machining center

The number of clicks: Updated: 2017-07-05

In fact, the emergence of linear motors makes the servo motor + rolling screw drive device very awkward, because the linear motor can replace the servo motor + rolling screw linearly to drive the linear three axes. Linear motors are generally used in high-speed machining centers . Generally, CNC machine tools rarely use linear motors to drive linear three-axis, because the current technology of linear motors to drive three-axis is still mature. Let me introduce the advantages and disadvantages of linear motors driving linear three-axis.

Servo motor + rolling screw drive linear motor drive

Advantages of linear motor-driven machining center

Linear motor driven linear three-axis has the advantages of fast speed, high efficiency and excellent rigidity. The speed of the linear three-axis drive by the linear motor is 2-3 times faster than the linear three-axis speed of the servo motor + rolling screw. The feed speed of the driving linear three-axis is 86m / min; because the servo motor + rolling screw is a transmission form, the rigidity is not as good as the linear motor.

Disadvantages of linear three-axis linear motor driven machining center

As the current technology of linear motors driving linear three-axis is not mature, linear motors still have many shortcomings, such as the high cost, large heat generation, and poor transmission stability. Linear motors are very expensive to manufacture and therefore expensive to sell. Due to the fast speed of the linear motor, a certain amount of heat will be generated during the high-speed movement. The faster the linear motor, the higher the heat. Therefore, the linear motor driven linear shaft device must be equipped with a cooling system.
