AUTOMATIC DRILLING AND TAPPING MACHINE
Abstract : A device, usually motor-driven, fitted with an end cutting tool that is rotated with sufficient power either to create a hole or to enlarge an existing hole in a solid material and also known as driller. Tapping is the process of making thread inside the drilled hole. This operation requires less force to operate. In this project the drilling machine uses pneumatic power in stead of motor power. The drilling operation is carried with the help of pneumatic cylinder which provide the up down motion to the drill tool. This project is very useful in industrial companies in order to save the time and manpower. This type of drilling machine consumes less time for operation and also no man power is required. After completion of drilling operation, the tapping process is carried out with the help of pneumatic power. In this arrangement the tapping tool is inserted in the machine tool head in stead of drilling tool. So that making the thread on the plate becomes very simple by implementing the tapping operation in the drilling machine. Time control unit is used to control the drilling operation time in the machine. This automatic is only applicable for continuous operation of drilling. Tapping operation requires less working force so that this force is provided by gearing arrangement. So this makes less revolution during the tapping operation.
? Noise produced
? More cost.
? It reduces the manual work.
? Quick operation
? Accuracy is more
? Low cost machine
? Its used multipurpose device like Grinding, screw driving.
