The built-in type, also known as electric spindle unit, is a unit that integrates the machine tool spindle with the spindle motor, also known as "high-frequency spindle" and "direct-drive spindle". The characteristics are high speed, high precision, high efficiency, and high dynamic and static stability. They are generally divided by application, such as for carving and milling, grinding machines, lathes, machining centers, etc.
