Working Principle of a Fully Automatic Tapping Machine
After the workpiece is secured in a fixture, the operator selects a preset machining program via the touchscreen. Driven by a servo motor, the machine’s spindle rotates the tap at the set speed and torque. When the tap contacts the workpiece, the control system precisely controls the feed rate, allowing the tap to enter the hole along a predetermined trajectory and cut the internal thread. When the set depth is reached, the spindle reverses, the tap withdraws, and a standard threaded hole is completed. The entire process is precisely controlled by the automatic tapping machine, requiring no human intervention.
