Itco INDIAN ENGG CORP stand among best Manufacturer, Exporter & Supplier of multiple types of Precision Vertical Drilling Machines & Gang Drill Machines special purpose as per custom requirement. Different sizes of drilling heads & tapping heads are mounted on a single platform/ table. Gang Drilling Machines are suitable for mass production of a component ensuring high performance and better productivity. The various machining operations like drilling, reaming, counter drilling, tapping etc are identified and accordingly the selection of drilling/ tapping heads is done. For machining operations where coolant is required, an independent complete coolant system can be integrated with these special purpose vertical drilling machines. These multiple heads are mounted on independent pillars/ columns spaced conveniently. The working base is accurately machined and hand scrapped for optimum finish. For fixing the drilling jig T-Slots are machined on the working base. Requirement of Power for Gang Drilling Machine is calculated on the basis of number of heads mounted. Sliding table can be mounted on the working base for indexing the job (without unclamping) between various drill stations. Indexing is done either manually by hand feed or Automatic indexing by means of hydraulic /pneumatic feed.
