1) Base
It is the bottommost part of the radial drilling machine. It is made up of cast iron because cast iron has high compressive strength. The base is used to support the assembly of parts on it. It also absorbs the vibrations and shocks induced by the machine parts.
2) Column
The column is present at one end of the base. It is a vertical pillar which act as support for rotating the radial arm in 360 degrees.
3) Table
It is mounted above the column. It is provided with T slots for mounting the workpiece directly on its face. It is usually round or rectangle in shape.
4) Radial Arm
This is the part which is connected to the column. This part can rotate 360 degrees around the column. The face of the radial arm is accurately machined and drill head slides over it. This arm goes up and down in the column. In big machines, hydraulics are used to move the arm up and down.
5) Drill Head
Drill Head is mounted on the radial arm and drives the drill spindle.
It encloses all the mechanism for driving the drill at a different speed and feeds.
6) Spindle
It is the part of the drilling machine that holds the tool of drilling machine and is responsible for its rotation.
7) Motor
The motor is present at the top of drill head which drives the horizontal spindle.
8) Chuck
Chick is present at the bottom of the spindle. It is used to hold the drill bit in its place.
9) Tool or Drill Bit
Drill Bit is used to drill the holes in the workpiece. It is the part that rotates and enters into the workpiece making a hole.
