How to Install Spindles

How to Install Spindles

(Ⅱ)

 

Today, we continue our series on how to install spindles.

 

4. How to install spindles before running:

(1)  Confirm the circulating cooling water for spindle sleeve has been opened;

(2)  Generally, the cooling water temperature should not exceed 35℃; 

a)  Cooling water temperature should not be too low;

b)  It is inappropriate for using tap water;

c)  If water is too cold, it can cause the internal air which is inside cnc spindle cooled and form in condensation;

The condensation will cause corrosion to the bearing and affect isolation;

 

(3)  Cooling water flow can be 3~5L/MIN;

(4)  Cooling water should be clean and no impurities, to avoid blocking the aisle;

(5)  Generally, the water in coolant tank is about 50L~100L;

Water pump suggestion: AB-25 or AB-50;

 

(6)  The distance between water inlet and water outlet should not be too close;

a)  Ensure cooling process in the coolant tank;

b)  The water temperature difference is better to reach 2~3 between water inlet and water outlet;

c)  Avoid hot water circulation to affect cooling effect;

 

5. Be sure that the power voltage and frequency converter is identical with cnc router spindle:

(1)  Set U/F converter curves according to the relationship between voltage and frequency;

(2)  The 4th core of the machine spindle plug should be earthed;

(3)  The 1st, 2nd and 3rd core should be connected with UVW of frequency converter;

 

6. How to install spindles when startup cnc router:

(1)  The first start up should be short-time run (start the inching function);

(2)  Check spindle direction;

If reversed, cut off the electricity without delay, and exchange any two inlet wires;

(3)  To new router spindle, it's better running in low speed:

After running 0.5~1.0 hour at a low speed, then step into high speed rotating; 

(4)  The starting time is about 10 seconds;

 

7. Running:

(1)  Listen:

      Check if the spindle sounds normal:

       If any strange noise by scraping or abnormal condition, close down the cnc machine at once;   

(2)  Touch:

      Check whether the heat and vibrations of cnc machinery is stable;

(3)  After running:

  Turn off the power;

  After cnc spindle stopped rotating:

a)  Upload cnc tools and router collets;

b)  Close water pump to stop water supply;

c)  Clean cnc router spindle, solid end mill after each use;
