Description: A differentials drive system with master lead screw system, tapping unit, Model GEM12 has been developed as a new concept in tapping. The complete system consists of the lead screw and a nut similar to a conventional lead system. The lead screw is coupled to the spindle, which helps in giving linear motion as well as rotation for the spindle. The nut on the lead screw also rotates through the drive coming from the set of gears, which finally define the pitch of the threads to be cut. Frequency converters and electronics are used to vary the speed of the spindle, a Suhner patent. Potentiometers help to control the linear distance travelled, and the feedback is also taken out of it. Flexibility and fast change over in the setup of the machine are advantages of such a system when compared to longer setup times of the lead system. Other products in range: self-feeder drilling units up to 28 mm capacity, high speed drilling units up to 40000 rpm, tapping units up to M20 tap capacity, multispindle heads and units for boring, milling, chamfering, reaming and countersink applications.
