A power operated machine tool which holds the drill in its spindle rotating at high speeds and when manually actuated to move linearly simultaneously against the workpiece produces a hole is called drilling machine.
Drilling machine is one of the simplest, moderate and accurate machine tool used in production shop and tool room. It consists of a spindle which imparts rotary motion to the drilling tool, or mechanism for feeding the tool into the work, a table on which the work rests and a frame. It is considered as a single purpose machine tool since its chief function is to make holes. However, it can and does perform operations other than drilling also.
Specification of a Drilling Machine
1. Size of the drilling machine table.
2. Largest bit the machine can hold.
3. Maximum size of the hole that can be drilled.
4. Maximum size of the workpiece that can be held.
5. Power of the motor, spindle speed or feed.
