Parts CNC machining machine tool casting industry has made a major development breakthrough. Advantages and disadvantages of linear three-axis linear motor-driven machining center In fact, the appearance of linear motor makes servo motor + rolling screw drive equipment very embarrassing, because linear motor can replace servo motor + rolling screw to drive linear three-axis. 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 linear motor-driven three-axis technology is still old enough.
Next, let me introduce the advantages and disadvantages of linear motor driving linear three-axis. Benefits of linear three-axis machining center driven by linear motor Linear three-axis driven by linear motor has the advantages of fast speed, high efficiency, and excellent rigidity. The speed of linear three-axis driven by linear motor is 2-3 times faster than that of servo motor + tumbling screw. The feed speed of servo motor + tumbling screw is generally 48m/min, while the linear motor The feed speed of the linear three-axis drive is 86m/min; since the servo motor + rolling screw is the transmission form, the rigidity is not as good as that of the linear motor.
Disadvantages of linear three-axis linear motor-driven machining centers Because the current technology of linear motor-driven linear three-axis is not mature enough, linear motors still have many shortcomings, such as expensive, high heat generation, and poor transmission stability. exist. The manufacturing cost of linear motors is very precious, so the price is also precious. Due to the high speed of the linear motor, a certain amount of heat will be generated during the high-speed movement. The faster the speed of the linear motor, the higher the heat generated. Therefore, the linear motor-driven linear shaft equipment must be equipped with a cooling system.
