DC Spindle

Choosing the right spindle is crucial for many CNC job. involves finding the right balance between the speed, power, and torque of the spindle.

choose a CNC spindle that has the RPM, power, and cooling your need for your material. for Wood and Aluminum, a spindle with 24,000 RPM and 1kW power is good. for Steel, RPM between 15,000-18,000 and power of 5.6kW is good for up to 12mm tool size.

DC spindles can be brushed or brushless. brushed motors are more affordable than brushless motors but require the replacement of burshes occasionally and have more vibrations than burshless motors.

choose a brushed DC spindle only if you intend to use it for engraving purposes. for all other purposes, you should get burshless motor to achieve a good finish.
