Drilling machines are used in garages, carpenter’s workshops and production halls thanks to their various size and purpose variations.
The machines are used to drill holes in the manufacture of machinery, equipment, generators and turbines for large hydroelectric power plants, assembly of pipelines in the oil and gas industry, domestic and industrial water supply.
Industrial drilling machines are not only represented by massive production models. There is also a more compact version – a magnetic drilling machine. They are used when working with large metal structures, of which ships and industrial machines are assembled, when installing power transmission towers and drilling metal at high altitude, field repair of railroad tracks and metal pipes.
Types of work performed on the drilling machine:
Reboring. Working through an already drilled hole with tools of larger diameter. Drilling makes it possible to achieve a high accuracy of machining;
Drilling holes both through and down to a certain level. Industrial machines can drill a hole up to 10 cm in diameter in structural steels and non-ferrous metals, as well as in carbide materials;
Countersinking. It is convenient for machining holes formed as a result of casting, forging, and stamping. Countersinking is used to align holes, reduce roughness, and make them more accurate. It is important that the workpiece be firmly clamped on a table or machine base;
Countersinking. This type of treatment is used only for the upper end of the hole, it allows you to make chamfers, indentations in the form of a cylinder or cone. Countersinking is the final stage of preparation of the hole, it is performed without changing the position of the workpiece in the clamp;
Boring with a chisel. Boring is carried out in previously prepared holes in order to coordinate their axes more accurately;
Reaming. This operation is used to bring the walls of a previously drilled hole to a high degree of accuracy and smoothness. There are roughing and finishing reaming;
Tapping a thread on the inside with a tap. Threading can be through or blind;
Smoothing. Smoothing, which is accomplished by means of roller mandrels;
Straightening. Machining for installation of fasteners of the end part of the holes.
