The CNC router machine mainly includes electric system, actuator system and mechanical structure. The performance of the machine is directly depended on the performance of these three parks.
The electric system mainly includes motion controller, drives, motor, power supply and inverter. Compared with the stepper system, servo system has a higher running speed, lower noise and precision advantage. But the stepper system can almost satisfy the requirement of the router and it’s easy to setup and adjust. The most importance advantage of stepper system is that it’s a very economical proposal. So the stepper system is still the main proposal in this industry now.
The actuator has both lead screw and rack system. The lead screw actuator most used in a small-scale router machine. It’s connected to the motor with the coupling or ratio wheel. The stiffness of the lead screw would decrease and more ripples would happen with the growing of the lead screw’s length. But the lead screw actuator has a better processing accuracy. The rack actuator most used in a large-scale router machine. It’s always connected to the motor with the ratio wheel and used double motors in the Y axis running synchronous. But the rack actuator’s precision is lower than lead screw.
