Some of the highly developed uses of the machine include reaming, tapping, spot facing and counter drilling. The drilling machine is intended for drilling small to huge and heavy work pieces. Radial Drill Machine consists of the following parts:
- Radial Arm– In radial drilling mechanism, the radial support holds and supports the drill beginning assembly and can be moved around on the extent of its length.
- Column– Column is the part of the radial support drill press which holds the radial arm. It fixes itself and the radial support to the base and allows flawless movement of the arm.
- Elevating Screw– inspiring screw is a portion of metal with screw-like circular thread. It helps in adjusting the upright height of the radial arm by raising or lowering it.
- On/Off Button– This button has an easy purpose of activating or deactivating the drill press.
- Arm Clamp– Arm fasten provides support and holds both, the column and the radial arm.
- Table– Table is the part of the mechanism located just below the radial arm. It is where the work pieces are fixed and worked on. This constituent and be raised, lowered or rotated in order to make easy the drilling process.
- Base– This part is permanent to the ground and is straight attached to the table and the column. This way it provides support to the whole mechanism.
- Spindle– This part is friendly at the entrance of the radial arm. It is the revolving 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 fabric or work piece. It is friendly to the radial support by the spindle.
Working
The work piece is permanent on the table. Height and reach of the radial arm are familiar before starting the drilling process. Once everything is arranged, the drill is twisted on and the drill chuck is lowered with help of a radial drill. The hole is generated in a work piece by exerting large force via drill head as it is lowered. This large force is resulting of high-speed rotation drill head. The drilling of hole and removal of metal is ensuing of shearing and extrusion.
