Technical description of a drill machine:
Definition:A device, usually motordriven, fitted with an end cutting tool that is rotated with sufficient power either to create a hole or to enlarge an existing hole in a solid material. Also known as driller.
Components:
Head
The head part of the drill press houses the spindle as it is attached at the top region of the spindle. It is responsible for the spindle movement because the spindle can only move upward or downward.
Spindle
Spindle is the most important part of the drill press that is used to hold the tool and is responsible for its rotation. The spindle of the tool is held with the help of arm that is gripped with the column. In order to keep the spindle in its place, the manufacturer has used a spindle return spring and the spindle moves up and down easily. The weight of the spindle is very useful in the performance of the drill press as counter balances the spindle spring. At the bottom side of the spindle, chuck is placed and this chuck is used to hold the drill bit in place.
Column
The column of the drill machine is used to tie the table. The work is hold in place by the table during the drilling process. It is a long rod in shape that stands vertical with the table. Both the column and the tables are placed at the 90 degree with each other.
Table
Table is also one of the best parts of the drill press. This is used to hold the working material in place. It is adjusted right at 90 degree to the column. It can be moved upward, downward and rotated around the column as required. The shape of the table does not matter. You can make a round shape or a rectangular shape table for your drill press.
Base
The base of the drill press is made up of the steel or iron. The main function of the base of the drill press is used to support the column and stabilize it. With the help of the base or the foot, the drill press can be placed in the upward direction.
Working principle: The rotating edge of the drill exerts a large force on the workpiece and the hole is generated. The removal of metal in a drilling operation is by shearing and
