Analysis to Uneven CNC Spindle Speed

It is worrisome that CNC spindle speed is uneven, sometimes speed up, and sometimes slows down.

Today, let's see the analysis to uneven cnc spindle speed from professional technicians!

1. First situation to cause uneven cnc spindle speed:

Haven't changed cnc converter before, or the new converter is the same brand as before:

(1) The power supply is not stable;

(2) Switch contact is not good;

(3) Software problem;

(4) Mechanical transmissions problem;

(5) Cnc converter problem:

① The plugin is loose;

② The contact is not good;

③ Converter has its own problem;

(6) Cnc spindle motor problem;

(7) Bearing is in poor lubrication;

2. Second situation to cause cnc spindle speed:

If converter had just changed, and works well before:

The parameter setting is not appropriate:

(1) Check if the parameter setting to spindle motor is right;

(2) If the current limit block is too small;

(3) If the acceleration/deceleration time is too short;

(4) Check if the setting of torque boost voltage is too big;

(5) If the voltage is stable;

(6) If the cnc converter has parameter optimization,

It's better optimize automatically to the motor parameters;

3. Second situation to cause cnc spindle speed:

Check if the router bits are suitable or had been broken;
