H&G Tapping Machines with leadscrew system

Adapted to each necessary task, two fundamentally different systems had been developed. In the series operated by hand are two opposing pulleys by a constant current drive motor. The right-and left-wing movement of the spindle is by pulling or releasing the control lever guaranteed. With functionality similar to a clutch of car is a very sensitive even the smallest screw threads (until M1) is possible. A blending of threads in thin and soft material is by using the leadscrew system prevented. This machine type can also be used without leadscrew. The automatic high-end machines will be threaded through a high-performance "Demag" brake (or servo motor) driven, each of the direction of rotation of the spindle holder. Through the 9-speed variable belt translation is the driving side of a driven gear. The translation within the gearbox ensures an output speed before delivery within a concerted wide speed range. For servo drives can be without changing the speed of pulleys to a display set. A blending of threads in any material is by using the leadscrew system prevented.
