Spindle Speed Control Method

by astech-cnctools

Spindle Speed Control Method

 

Every sculpture material has a reasonable speed range. Usually, spindle speed rpm is between 18000 and 24000.

 

Spindle speed control affects not only processing performance, but also service life of carbide tool bits and cnc spindle.

 

So, we should learn spindle speed control method according to different material hardness.

 

1.    Spindle speed control according to different control system:

(1)  NC Studio control system:

   In the toolbar of NC Studio control interface, there is a slider marked as "ON".

Control spindle speed by dragging the slider;

   Adjust converter which controls spindle speed;

 

(2)  DSP handle control system:

   Press and hold the "ON/OFF" key, then adjust rotational speed by pressing "Z+" key or "Z-" key;

   As different DSP handles, some could directly press "Z+" key or "Z-" key to control spindle speed;

 

2.    Usually, the harder engraving material, the slower rotate speed;

The sticker processing materials, the higher rotation speed.

So, high speed or slow speed is not absolute, we need to experiment and to practice.

 

3.    Spindle speed control on output power:

(1)  From experience, when spindle speed slows down, motor output power is also reduced;

When motor output power reduced to a certain degree, it will:

a)  Affect router processing;

b)  Have greater harm to working performance and tools lifetime;

 

(2)  Usually, the higher rotation speed, the higher output power, then the router processing is more smooth;

(3)  So, when determine spindle speed, be sure that router spindle has a certain output power;

 

4.    Supplement on spindle speed control:

(1)  If spindle speed is not adjustable, or with small adjustable range, it means cnc router application is greatly limited, because different materials should with different spindle rotate speed;

(2)  To spindle speed, it has obvious difference from engraving and cutting different materials.

Certainly, it's also strongly related to stone engraving tools selection;

 

Overall, everything has its limit, and everything is not absolute. Of course, spindle speed control is no exception. So, control spindle speed in a reasonable range is the best and most important method.
