Water-cooled spindles are found to be more effective in temperature regulation as their temperature does not typically exceed 40 degrees after water circulation. Maximum rotational speed. An air-cooled spindle can clock a rotational speed of 18,000 rpm. In contrast, a water-cooled spindle operates at 24,000 RPM.

Consider the specific cutting requirements of your application. Higher torque allows for more efficient material removal, especially when working with tougher materials or using larger cutting tools. Choosing a spindle motor with sufficient torque is essential to effectively handle your specific machining tasks.

Spindle motors can be induction-type (a.k.a., asynchronous) or synchronous-type.

The main uses of spindle motors are power sources such as drilling, cutting and grinding tools, and tools such as drills are attached to the tip. It can also be used for machining robots, and is used for machining high-precision parts by taking advantage of its high controllability.
