Elscint exports Double Headed Automatic Tapping Machine to Armenia

Elscint recently completed an order for a double head Automatic Tapping Machine. There were three different components which required tapping. The tap pitch was different for each of these 3 components. Additionally, each of the components required left hand and right hand tapping. All these changeovers were required to be done in the same machine. Hence, Elscint suggested a single lead screw design tapping machine with double head tapping arrangement. This ensured that changeover between various tap sizes was easy. For two components, a single bowl was used with changeover tooling while the double gravity track was changed for each of the components. The third part required a separate bowl along with a separate gravity track. The changeover between bowls and the tracks was made easy with dowel locking for ensuring proper alignment. The advantage was saving of costs by using a single machine instead of 6 machines. The components were fed through the bowl feeder in two outlets to the gravity chute. At the tapping station, tapping took place with the help of a specially designed double spindle tapping attachment. The components were stopped with an (patented) Elscint pneumatic escapement while the tapping took place. Further, the components were also clamped separately to ensure they do not twist or turn during tapping. After tapping, the tapped components were released / unloaded to fall into a bin. The machine had provision to run either both or either of the components. The machine had a PLC and a HMI by which the operator could select most of the operations. This provided the customer with the required flexibility for its production run. The machine had option of running a coolant or tapping oil. Recirculation of the oil / coolant was also provided for. The complete machine was enclosed in a dust free polycarbonate cover. The machine was dispatched to the West Asian country of Armenia. You can watch the video of this tapping machine for one part and for another part.
