BME 4.2 DRILLING MACHINE AND OPERATIONS - YouTube Drilling is a cutting process that involves the use of a drill bit to cut a circular-shape hole in a workpiece. The removal of metal in a drilling operation is by shearing and extrusion. View Complete details. This permits the table to swing up to 45° in either direction for angular and helical milling operations. 30.2.5 Milling. The drilling machine The Drilling operations are carried out in most of the industry using different drilling machine as per requirement. They can perform operations other than drilling, such as countersinking, counterboring, reaming, and tapping large or small holes. —Edward Young Introduction Drilling holes is the most common of all machining processes, and the tool most commonly used to make them is the twist drill. 4. Drilling: Operation of producing hole by removing metal from solid mass using twist drill. A special mechanism permits the boring bar to be locked to the feed nut and yoke to prevent the drill from spiraling into the hole before the hole is completely drilled. for all operations. Drilling is the process most commonly associated with producing machined holes, because it is simple, quick and economical. operation and tools are fed automatically during the power drilling operation. If you put a drill bit in a milling machine and try to feed the table in X or Y, bad things will happen. The universal machine can be fitted with Subject - Manufacturing ProcessesChapter - Drilling Operations: Drilling, Reaming, Boring, Counter Sinking, Counter Boring, Counter Sinking, Spot Facing, Tap. Drill Machine brings about conductive features as it saves time and energy applied for a particular operation. Use:- Drilling machine is used to drill blind and through holes in work pieces. . Working of Radial Drilling Machine . Initially a hole is drilled to the nearest size and using a boring tool the size of the hole is increased. D v N. π Spindle: = Feed rate: r = f Nf. It is a small machine designed for drilling small holes at high speeds in light jobs. Standard drill bits in various sizes are available in the market. Gang drilling machine. Nearly 75% of the metal removed by machining This press has several work heads (avoid confusion with spindles, several of which may be present in one work head). At starting when the power supply is given, the spindle rotates which is driven by the motor. The column contains an oil reservoir and a pump which lubricates the spindle. Column & Base. Column including base is the main casting that supports all other parts of milling machine. Hand drills are used for screwing and fastening. 2- The same result is carried out in some machines by holding the drill stationary and rotating the work as on the lathe. It enables doing several successive operations simultaneously. There are many types of drill machines available in the market for performing various operations. It is an operation of producing a circular hole in a work piece by forcing a drill against it. The mobility of operation for a drill press is limited to the aforementioned verticle movements.
