A CNC linear actuator is a motorized device used in Computer Numerical Control (CNC) systems to move a load or tool in a straight line. This linear motion can be precision-controlled and is typically used for precise positioning or automated tasks, such as industrial milling, cutting, drilling, or any other motion control tasks requiring movement along a linear axis. Linear actuators are often used in conjunction with stepper or servo motors and can be either belt-driven or ball-screw-driven. They come in various stroke lengths, speeds, and load capacities, and can be customized to suit specific application requirements.
In CNC systems, CNC linear actuator is responsible for translating the digital information from the CNC controller into physical movement along a linear axis. This can be accomplished through a variety of motor types, including stepper or servo motors, which provide accuracy and repeatability during positioning and movement of the load or tool.
CNC linear actuators come in different types. The type of CNC linear actuator chosen depends on the specific application and its requirements. For instance, some linear actuators use belts to drive the load or tool while others use a ball screw mechanism. Ball screw actuators are typically more accurate and are used in applications where precision control is critical, while belt-driven actuators may be used in applications where cost or speed is more important.
When selecting a CNC linear actuator, several factors should be considered. For instance, the stroke length, speed, and load capacity should match the requirements of the application. The actuator’s precision, repeatability, and accuracy should also be evaluated, as should the motor type and control system.
In summary, CNC linear actuators are essential components of motion control systems used in industrial applications requiring precise and automated movement along a linear axis.
