When the operator turns on the motor, it starts spinning. With the help of a gear or pulley drive, the power of the motor is transmitted to the spindle.
There is a medium-size control wheel on the right-hand side of the drill head. By using this wheel, the operator starts applying slow-pressor on the job which is pre-located below the drill bit.
Due to the pressure, the excess material starts coming out of the workpiece and a hole starts to form inside the job.
When it comes to the construction of the radial drilling machine, the base is the most important part because it weighs the rest of the machine parts. At the rear-end of the base, the column is placed. On the other hand, t-slots are made on the front-end surface. Nowadays, a small coolant tank is also made inside the base.
If we talk about the column, mainly two parts are attached to it. Radial arm and elevating screw. With the help of elevating screw up-down movement is given to the arm.
A sliding drill head is mounted on the arm. On the head, there various small to medium size parts are fitted. In which motor, spindle, depth gauge, and control panel are chief.
Two wheels are also fitted on the drill head, one is to feed the spindle, and the other is for the head’s sliding movement over the arm.
At last, there are numerous levers fitted to lock or unlock radial arm and spindle movements.
