Radial arm drilling machine |
| The radial arm drilling machine has many unique movements that make the radial drill machine different from any other drill machine. In fact, a radial arm is the only reason why the machine is called a radial drill. You can rotate the arm 360 degrees around the column. |

| Radial Drilling Machine Parts: |
| Base |
| The base is the
most important part of the machine. Usually, it is made of
cast iron. The reason behind this is that when you use the
radial drill for machining, there will be a lot of vibration
in it. And because of this vibration, the machine parts
could break. In this situation, a base made of cast iron is very helpful. Because cast iron has a remarkable ability to absorb the vibration produced by the machine parts. But that is not the main function of the base. The main function of the base is to provide support to the assembly mounted on it. Another thing you should know about the base is that most radial drill machine manufacturers make t-slot on the surface of the base so that you can fit worktable or other clamping devices easily. |
| Column |
| The column is a
vertical pillar that is mounted on the rear side of the
base. The main function of the column is to support and hold
the radial arm assembly. Just like the base, it is also made
from cast iron. But before mounting the column on the base, the manufacturer of the radial drill has to make the column surface super smooth. There is a good reason behind it, You see, the radial arm that is mounted on the column is designed in such a way that it can slide easily up and down on the surface of the pillar. If the surface finish is not good, there will be a lot of friction between the two parts while moving the arm up or down. |
| Radial Arm |
| The radial arm
is the coolest part of all. Because it has so many unique
movements that make the radial drill machine different from
any other drill machine. In fact, a radial arm is the only
reason why the machine is called a radial drill. Here is the list of movements of the arm along with benefits: |
|
| Drill Head |
| Drill Head is
the driving force behind the radial drill. It is mounted on
the radial arm. It contains many important elements such as
gearbox, motor, spindle, depth gauge, control panel, and
many more. By using the control panel, you can change the speed of the spindle, and with the use of a depth gauge, you can set the depth of the drill bit. You can also switch between auto or manual feed mode by using a spindle wheel. |
| Spindle motor |
| The motor is mounted just above the drill head. Its main job is to provide rotary drive to the spindle. When you are buying a new radial drilling machine, you should check for the motor power. The more drill capacity you want the more powerful motor you will need. |
| Spindle |
| The spindle is a rotating shaft with a fixture that holds your cutting tool. The main function of the spindle is to support your tool and provide a rotary drive so that it can easily make a hole in your workpiece without breaking or falling. |
| Table |
| Table, as it
sounds, is a worktable. It provides you the facility to hold
the workpiece during the drilling operation. Just like the
base, the table also has a few t-slots on it so that you can
fit clamping devices to hold your job. Usually, the table comes in a round or rectangle shape. (most users do prefer rectangle table). But you can also purchase a modified table so that you can drill a cross hole in your workpiece if you want. |
| Spindle feed handle |
| The spindle feed handle is to move the spindle and the dill bit into the work to a specific depth |
| Drill head movement handle |
| This handle allow the drill head to move horizontal on the radial arm |
| Arm elevating screw |
| This screw allow the radial arm to move vertical up and down the column |
| Elevating motor |
| The elevating motor is connected to the elevating screw and drive the elevating screw for vertical up and down movement of the radial arm on the column |
