    Spindle Type of CNC Router

    Spindle Type of CNC Router

     

    CNC Router spindle is an important part of CNC router.

    Today, let's study spindle type.

     

    Generally, there are two spindle types: precision machined spindle and high power cutting spindle.

     

    1.    Precision machined spindle:

    (1)  Feature:

    Cnc spindle motor is usually:

    ①   High-speed variable frequency motor;

    ②   Smaller than 250W;

     

    (2)  Application:

    This spindle type is more suitable for processing particular subtle materials, such as: seal, nameplate, breast plate, gifts articles, etc;

     

    (3)  Advantage:

    Low noisy, high running speed, high precision;

     

    (4)  Disadvantage:

    Poor capability in cutting thicker materials (cutting ability is also related to machine configuration and good CNC tools);

     

    2.   High power cutting spindle:

    (1)  Major application:

    This spindle type is mainly used for cutting thick materials, especially for 2D cutting, 3D lettering, etc;

     

    (2)  Feature:

    High power, good cutting ability;

     

    (3)  According to characteristics, spindle motor can be divided into AC brushless motor and AC brush motor;

    The main difference is:

    ①   To rotation speed:

    a)  Ac brushless motor is with higher rotation speed and 70060000 RPM variable-speed range;

    b)  To AC brush motor: the maximum speed is not more than 24000 RPM;

     

    ②   AC brushless motor is with higher precision, less wear and noise;

    ③   To locked-rotor characteristic:

    a)  Ac brushless motor is better;

    Because with specific current-limiting circuit, ac brushless motor won't be burned if blocked in short time;

    b)  In overloaded running or blocked, ac brush motor will be smoking and burned very quickly, and couldn't be repaired;

     

    ④   To the lifetime:  

    a)  Ac brushless motor adopts AC frequency conversion technology:

    Professional with longer service life;

    1 year warranty for free;

    Could maintain by changing high-speed bearing;

    b)  The lifetime of ac brush motor is around 300 hours, then have to change motor or motor carbon;

    Usually, it is not be covered by the warranty;
