CNC Intelligent Tapping Machine

The CNC intelligent tapping machine is suitable for all industries involved in machinery manufacturing, including machine tools, mold machinery, plastic machinery, printing machinery, packaging machinery, engineering machinery, automobile and motorcycle parts, aero engines, rolling stock, tobacco machinery, and general machinery.

CNC Intelligent Tapping Machine


This device offers overload protection, adjustable torque, and continuous tapping. The spindle has a radius of free movement of 900/1900mm.

It is lightweight, flexible, efficient, and possesses advantages that other similar devices cannot match. The rocker arm type CNC tapping machine overcomes the limitations of lathes, drilling machines, or manual tapping, saving time and labor while reducing the risk of broken taps.

The torque is stable, and its lifespan is long. Additionally, repeated positioning and cutting speed are fast, resulting in high production efficiency. Furthermore, the safe torque clamp ensures minimal tap damage. The through hole and blind hole tap are not easy to break, and the thread precision is high.

This device has a broad scope of work activities, and it is unnecessary to move heavy workpieces. It is simple to operate, lightweight, efficient, and has a low working intensity. It is suitable for all types of light and heavy work.

Operation & composition

(1) operation

After connecting the power, turn on the power controller and set the tapping speed. Press and hold the forward rotation button to engage the servo motor, which converts the voltage signal into torque and speed output for tapping operation. Once the tapping is complete, hit the bottom and press the reverse button to withdraw the thread.

This machine boasts high tapping precision, and a pass gauge can be used to detect it.

(2) Composition

  • Servo motor: drive the control object by converting the voltage signal into torque and speed
  • Controller: power control and torque overload protection
  • Display: control of the speed of the incoming and outgoing thread
  • Tap Torque Protection Chuck: Adjust the torque of the collet. The thread tapping reaches the bottom of the blind hole beyond its torque, and the slip protection will work.
  • Bracket: height can be adjusted up and down, tapping at any position within the operating radius.

Use adjustment

1. The torsion force of the torsion collet is typically set at the factory, but it may need to be adjusted and set before tapping tough materials or after using it for some time.

2. The torque cylinder housing has two small holes that allow for torque adjustment of the half-groove, which is crucial for adjusting torque control below M3.

3. To adjust the torque, use a one-word screwdriver to pick up the buckle and insert needle-nosed pliers into the two round holes on the torque adjustment ring. Turn clockwise to increase the torque and counterclockwise to reduce it.

4. Once adjusted, insert the buckle into the small hole of the collet jacket, and the torque will remain unchanged.

5. The torsion collet ensures high-precision threading and should not be randomly placed, littered, or chaotic, as this may affect tapping accuracy.
