A drilling machine is a tool used to create round holes in workpieces by rotating a cutting tool known as a drill bit and feeding it into the material.
A typical drilling machine consists of several key components:
- Base: The foundation of the machine, providing stability and support for all other parts.
- Column: A vertical structure that connects the base to the table and often houses internal components like the spindle.
- Table: A movable horizontal platform where the workpiece is placed; it can be adjusted vertically to control drilling depth.
- Spindle: A rotating shaft driven by a motor, responsible for turning the chuck and drill bit at the required speed.
- Chuck: A clamping mechanism that securely holds the drill bit in place and allows for easy bit changes.
- Drill Head: Contains the motor and driving mechanisms; it’s mounted on a sliding system to raise or lower the spindle during drilling.
- Controls: Includes buttons, levers, and dials used to operate the machine, adjust speed and torque, and manage other settings.
- Additional Components: May include a coolant system to reduce heat, a work light for visibility, and a chuck key for bit changes(Precision, 2023).
