Which component of a vertical mill contains the spindle and motor?

The head of a vertical mill is the critical component that houses both the spindle and the motor. The spindle is essential as it holds the cutting tool and rotates it to perform milling operations. The motor provides the necessary power to the spindle, enabling it to achieve the desired speed and torque for cutting metal materials effectively. The design of the head allows for the vertical movement of the cutting tool, which is vital for making precise cuts at different depths.

In contrast, the tailstock serves typically to provide support for the workpiece or additional tooling but does not contain the spindle or motor. The gantry is a structural support component that may house the mill's framework but is not involved in the cutting processes directly. The table is where the workpiece is mounted during machining, and while it is crucial for positioning, it does not contain the spindle or motor mechanisms.
