To the list of basic machining operationsmaterials included drilling. With the help of special equipment, the master forms holes with certain parameters, which can later perform various functions. Moreover, events of this kind are carried out both on individual elements of building materials and on finished structures. In particular, the drilling of a hole in the partition can be done with the aim of laying communication routes. Depending on the characteristics of the material being processed, appropriate equipment is used.
Чаще всего данная операция представляет собой cutting the material, as a result of which a cylindrical hole is formed. But there are other sections - it depends on the tool used. In determining the parameters of the resulting hole takes into account two main characteristics - depth and diameter. In accordance with the required performance, equipment with a cutting head of a suitable size is selected. As for the tool itself, with which you can drill a hole, it is represented by a wide range of devices and units with different characteristics. The most popular electric drills that can be used in working with solid materials. The main thing - to choose the appropriate nozzle. For soft materials it is enough to use manual mechanical drills.
Для обработки металлических деталей обычно use electrical apparatus that is supplied with carbon steel drills. Before work it is very important to correctly mark the future holes. This is usually done by core. This device even on hard surfaces allows you to form a conical recess, which will become the basis for "drilling". In order not to spoil the workpiece, it is advisable to drill holes in the metal only with heads that have cutting edges. The presence of the latter depends on the quality of sharpening the drill. The fact is that the angle of the cone can be different and is determined by the hardness of the material for which it is intended. The harder a metal grade is, the larger this angle should be, for example, steel is usually sharpened to 120 degrees.
The tree is one of the most pliable inprocessing of materials, which led to a wide variety of tools that allow to perform this kind of drilling. The simplest way to implement such a procedure is to use a gimlet, but it is only suitable for forming holes of small diameter. The drill is mainly used. It is enough to use a mechanical device in which the drill is mounted. Despite the soft structure of the material, drilling holes in the tree requires great care. It is necessary to strictly maintain the verticality of the work item and at the same time provide moderate pressure. The quality of performing such operations depends largely on the position of the master. In the process of radial drilling of cylindrical wooden products, the drill can “lead”. Such phenomena can be prevented with the help of a conductor, which will provide the necessary balance of the position of the functional element.
This task is the most difficult becauseWall construction materials are distinguished by their hardness and rigidity. The most effective tool for such tasks is a perforator with a diamond crown, but in some cases you can do with an electric drill. The most important thing is to choose the right device for performance. The power of the device should be not less than 600 W, and the frequency - up to 2500 r / min. The greatest difficulties can be caused by drilling large holes for laying ventilation lines. The diameter of such a channel can be 18–20 cm. A carbide drill with a diameter of at least 12 mm will help to create such a hole. That is, the formation of the desired hole size will have to perform a whole series of approaches. To begin with, it is necessary to mark the contours of the future channel, and then with small indents to make holes through them. At the final stage, it will be possible to carefully drop off an unnecessary fragment.
Mechanical operations entail strongoverheating of work items. The negative consequences of such processes can be reflected in the form of damage to the processed material, and in the deformation of the drill. To prevent overheating, use coolants and lubricants. For a mechanical tool, ordinary water will suffice, and if it is planned to drill the hole with a powerful electric apparatus, then a special emulsion should be prepared. In addition, work with the walls may be accompanied by the abundant formation of concrete dust. To eliminate contamination of the entire site, it will not be superfluous to initially provide for the possibility of supplying the power tool with a special vacuum cleaner that will collect garbage during the operation.
Technological development of constructionThe tool allows us to qualitatively perform a wide range of machining activities, including drilling. And not only the equipment is improved, but also the cutting elements. Improvement of high-strength carbide nozzles allows you to cope with metal and brick. Moreover, it is possible to drill holes of this type without connecting specialists. True, the basics of operation of power tools and in general the features of the technological process is still necessary to know. For their part, manufacturers of drilling equipment also tend to meet the needs of the average consumer. As a result, along with an increase in technical and operational parameters, such a tool acquires ergonomic handles, safety systems and protection from the same overheating.
