Technical description of a drill machine

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

Steps to use an Electric iron

Steps to use an Electric iron:

1.Make sure that the garment is meant to be ironed.

 Check the tags for ironing instructions. If the tags don't tell you which setting to put your iron, then look to see if they indicate what material the fabric is made of. Many irons order their settings by the type of 

material: e.g. wool, cotton, polyester.

2

Set up the ironing area. Use an ironing board, if possible. If you don't have access to an ironing board, then use a flat, sturdy surface like a table or a counter. The ironing board is designed to absorb heat and moisture without taking damage. Make sure that you don't iron on a highly flammable surface.

3

Fill the water reservoir of the iron. If your iron features a steam function, then you may need to add water. Look for a large, detachable water chamber on the top of the tool. Add filtered water nearly to the brim.

• Make sure that you use filtered water! This may help you avoid calcium build-up in your iron, which could clog the steam spouts.

4

Lay out the garment. Arrange the item of clothing so that it lies perfectly flat on the board. Make sure that there are no wrinkles! If you iron over a wrinkle, then you will press a creased line into the fabric.
