Advantages and Disadvantages of Linear Motor Driven Machining Center

In fact, the appearance of linear motors makes servo motors + tumble screw drive equipment very embarrassing, because linear motors can replace servo motors + tumble screw to drive linear three axes. Linear motors are generally used in high-speed machining centers, and general numerical control machine tools rarely use linear motors to drive linear three axes, because the current linear motor drive three-axis skills are still old enough. Let me introduce the advantages and disadvantages of linear motor drive linear three axes.

Linear motor drive machining center linear three axis benefits

The linear motor drives the linear three axes with the benefits of fast speed, high efficiency and excellent rigidity. The speed of the linear motor driving the linear three axes is 2-3 times faster than that of the servo motor + tumble screw driving the linear three axes. The feed and feed speed of the servo motor + tumble screw driving the linear three axes is generally 48m/min, while the feed and feed speed of the linear motor driving the linear three axes is 86m/min; because the servo motor + tumble screw is a transmission form, the rigidity is not as good as that of the linear motor.

Disadvantages of Linear Motor Driven Machining Center Linear Three Axis

Due to the fact that the current skills of linear motors to drive linear three axes are not very old, linear motors still have many shortcomings, such as the existence of precious price, large heat generation, and poor transmission stability. The production cost of linear motors is very precious, so the price is also precious. Since linear motors are fast, a certain amount of heat will occur during high-speed movement. The faster the speed of linear motors, the higher the heat generated, so it is necessary to equip linear motor drive linear shaft equipment with a cooling system.
