Drilling

Drilling

The shaping of material depending on the type of component that is to be created requires a different kind of process. We know that our customers need various parts, hence, we offer a full range of services that include metalworking by various processes. One of them is drilling, which we will talk about now.

Drilling – basic information

This type of processing is described as a type of machining (such as milling, turning and grinding). For what reason? The application of tools to the material causes the removal of excess material, in other words, material that is not necessary.

This process is applied to solid materials – in this case, metals – by use of a special tool. This tool is the drill bit, a special termination of an automatic machine. The result of this operation is a round opening. This is the most commonly achieved shape, however, it depends on the working end of the tool. Using a special drill, one can also achieve polygonal openings, triangular or square ones.

In most cases, the work piece remains immobile, with the rest of the device moving.

Activities performed during drilling.

Metal processing using this method allows the following:

• creation of small openings in the material – in order to achieve more space to introduce the working bit of the machine. This is called a blind hole – as opposed to a through hole;
• creation of full holes – or through holes;
• increasing of existing hole diameters – this operation is applied when the target opening is supposed to have a larger diameter. First, a smaller hole is made so as not to destroy the material. Then, a larger and wider drill bit is used that allows one to create an opening with the required size;
• execution of internal hole deepening – this activity entails increasing the initial diameter of a part of a hole in metal or in a different material. This allows one to hide the screw head, spacer or washer;
• execution of an external deepening – altering the front surface around a previously made hole;
• finishing processing – this method is used to achieve precise dimensions and limited roughness of material.
