Which component is responsible for amplifying voltage signals in a CNC machine?

Machine Tool
Servo Amplifier
Feedback System
Program Input Device

The correct answer is: Servo Amplifier

The servo amplifier plays a critical role in the operation of a CNC machine by amplifying voltage signals. These signals are crucial for controlling the movement of servomotors, which drive the machine's axes. The amplifier takes low-level control signals from the CNC controller and boosts them to a level that can effectively drive the motors. This process ensures that the required torque and speed adjustments are accurately achieved, allowing for precise movements during machining operations. Without the servo amplifier, the signals generated by the CNC controller would be insufficient to directly control the powerful motors used in CNC systems, leading to sluggish or inaccurate machining.
