A radial drilling, also known as radial arm press machine, is one of the most common and useful machines employed in the industry. It has a geared drill head that is placed on an arm assembly. This arm assembly can be moved around to the extent of its arms reach. Some of the advanced uses of the machine include reaming, tapping, spot facing and counter drilling. The drilling machine is meant for drilling small to large and heavy workpieces. Radial Drill Machine consists of the following parts:

• Radial Arm – In radial drilling machine, the radial arm holds and supports the drill head assembly and can be moved around on the extent of its length.
• Column – Column is the part of the radial arm drill press which holds the radial arm. It fixes itself and the radial arm to the base and allows seamless movement of the arm.
• Elevating Screw – Elevating screw is a piece of metal with screw-like circular thread. It helps in adjusting the vertical height of the radial arm by raising or lowering it.
• On/Off Button – This button has a simple function of activating or deactivating the drill press.
• Arm Clamp – Arm Clamp provides support and holds both, the column and the radial arm.
• Table – Table is the part of the machine placed just below the radial arm. It is where the workpieces are fixed and worked on. This component and be raised, lowered or rotated in order to facilitate the drilling process.
• Base – This part is fixed to the ground and is directly attached to the table and the column. This way it provides support to the whole mechanism.
• Spindle – This part is attached at the mouth of the radial arm. It is the rotating part of the drill press and holds the drill head.
• Drill Head – Drill head is the part of the drill press that penetrates through the material or workpiece. It is attached to the radial arm by the spindle.

Working: The workpiece is fixed on the table. Height and reach of the radial arm are adjusted before starting the drilling process. Once everything is arranged, the drill is turned on and the drill chuck is lowered with help of a radial drill. The hole is generated in a workpiece by exerting large force via drill head as it is lowered. This large force is resultant of high-speed rotation drill head. The drilling of hole and removal of metal is resultant of shearing and extrusion.

Drilling Works In the Petroleum Industry

The oil field and petroleum production industry poses certain special challenges. It is a heavy machinery industry, handling equipments exposed heavy corrosion and mechanical breakdowns sometimes in far off areas. Radial drill equipment is vital in numerous repairs handling very large work pieces associated with oil exploration. Some special applications include;

Countersinking

A conical cutter is fitted to the equipment to create a bevel shape or a tapered end. This process is important in creating the bore for flat-headed screws. Common angles of the counter screws are 82 degrees and 60 degrees.

Counter Boring

This is a process of enlarging the top end of a bore up to a certain depth, and creates a square shoulder on the produced bore. Counter boring is done to allow the heads of the screws to properly flush with the surface of work piece.

Spot Facing

This is a delicate process of smoothening off a round edge of the bore to create a level-sitting surface of the countersink. It is also used for surfaces such as washers, bolts and nuts to fit tightly below the surface of the work piece.

Tapping

This is also well achieved using the radial drill. This is a process of creating a thread in a drilled bore. During this process, the machine is not necessarily powered so that the chuck is turned by hand gradually until proper threads are created. Tapping of larger holes require positioning of the tap using the drill chuck and a tap wrench is used for greater power and grip to be achieved for tapping.

Reaming

This is the process of enlarging a small hole to the targeted diameter. In the petroleum and the oil field, precision is very important and this is a critical process used to achieve precision. The holes are drilled to smaller dimensions then rimmed to reach the required diameter. For greater precision, a bore should be drilled and reamed while still on the same set up.
