Itco INDIAN ENGG CORP is manufacturing, exporting & supplying state of art semi automatic Drilling and Tapping Machine in INDIA & abroad. These Industrial Tap Drill machines are custom designed and fitted with special best quality bearings. Reliable branded electrical components are fitted in tapping attachment / electrical panel for economical high precision production of drilling and tapping operation. This Universal Tapping machine is suitable to tap any type of thread inside a vertical hole. One can do threading in Metric or BSW threads, Left Hand (LH) or Right Hand (RH) threads depending upon the machine tap selected. While using these semi automatic drilling tapping machine, tapping drill sizes are selected from drill and tap chart. Working of this electric tapping machine is very simple as the drill machine reverse forward motion is achieved by limit switches. There are two limit switches operated by means of an adjustable cams which are used for Tapping in blind holes. While tapping through holes foot control switch is provided. These are semi automatic tapping machine i.e. the operator has to bring the tap towards the hole by manual action and once few threads are cut (1 to 2 nos) no further hand feed is required and the tap automatically advances towards the depth set and withdraw back successfully to home position. To switch between drilling and Tapping process mode a selector switch is provided. Machining of External threads is also possible by using a special purpose tapping tool. These Vertical Tapping machines are simple to operate, very accurate and offers a unique combination of drilling & tapping operation suitable for mass production/ tool room jobs.
