Operating CNC tapping machine and composition：
Connected to power, open the power supply controller, set the tapping speed, press and hold the positive rotation, servo motor, the voltage signal into torque and speed output of tapping, tapping into the bottom hold the reverse button back wire. Power wire of high accuracy, general gage can detect.
1 servo motors: the voltage signal into torque and rotational speed to drive the control object
The 2 controller: power control and torque overload protection
The 3 screen: into the back wire speed control, conditioning
4 tap chuck chuck torque: torque maintenance regulation size, tap at the bottom of the blind hole tapping to exceed the torque, slip maintenance.
The 5 bracket: adjustable height adjustment, operating within a radius of arbitrary orientation.

Adjust the NC tapping machine：
1, general torsion collet torque at the factory has been set, but the data is strong attack or use after a period of time, it is necessary to re adjust, the set torque.
2, torsion collet case with 2 holes, promised to do half a groove torque adjustment, which is very important in adjusting the torque control under M3.
3, using a slotted screwdriver, a retaining ring, with 2 round nose pliers in the torque force adjusting ring on the inner, clockwise anti clockwise torque is added, decrease torque.
4, after adjustment, the retaining ring holes into the collet housing thrust, torque is no longer changed.
5, is to ensure that the screw torque collet high precision, so the torque collet not random, litter, broke, avoid the influence of tapping accuracy.

NC tapping machine characteristics：
(1) the torque and long life
(2) repeat positioning agile, fast cutting speed, high production efficiency;
(3) safe torque Jane clip ensure tap less damage; through holes, blind holes continuously tap, thread accuracy;
(4) the scope of activities of large, heavy workpieces without moving;
(5) simple operation, light weight, high efficiency, lower working strength, suitable for all kinds of heavy work.
