3 Way Drilling Machine

A machine for drilling, reaming, counter boring, and tapping holes. especially : a power machine for drilling holes in metal (as a drill press or radial drill)Pillar drilling machine. Radial drilling machine. Gang drilling machine. Multi-spindle drilling machine.Drilling operation is the first contact between the formation and the nonnative fluids and equipment. Drilling fluids play a vital role during the drilling operations by lubricating the bottom-hole assembly, cooling the drilling bit, lifting-up the cuttings, and forming impermeable filter cakes.Working Principle of Drilling Machine: When the power is given to the motor, the spindle rotates and thereby the stepped pulley attached to it also rotates. On the other end, one more stepped pulley is attached and that is inverted to increase or decrease the speed of the rotational motion.
