Modern drilling machines

Drilling machines are machines for processing and drilling holes. They are used for countersinking, tapping, drilling, threading, as well as other types of processing parts of the product. The main tools used in drilling machines are taps, drills, countersinks, and other types of cutters.

The principle of operation of this equipment is the rotation and translational movement of the instrument along a certain axis. Drilling machines, depending on their characteristics, can be divided into classes: horizontally drilling, vertical drilling, boring, centering and multi-spindle. In this case, they are subdivided according to the material being processed. There are equipment for processing and drilling of metal, stone, plastic, wood, glass, etc.

The most common machines are drilling vertical direction. Their distinctive feature is that the spindle is located vertically, while the workpiece is attached to the table of the machine itself. The alignment and alignment of the tool with the workpiece takes place by moving the part around the table. They are used for processing and drilling small parts. Widespread found in the shops for the repair of equipment, as well as in the manufacture of small batches of products.

To process parts that are large in size, horizontal drilling machines are used. In them, the part is fixed fixedly, while the alignment of all machined holes occurs by moving the spindle. They are used for processing and drilling holes of a large depression.

Multi-spindle drilling machine is used for machining parts with several holes. Its characteristics allow the simultaneous processing of several holes. There are models with fixed and adjustable spindles. Centering machines are needed for drilling and machining holes in the end of the workpiece. These machines are equipped with cutters to remove part of the parts before the production of centering.

To perform several functions, there are models that can perform operations on milling, drilling, cutting. This is an aggregate or combined apparatus, which can include a cutting, boring, milling drilling machine. The price for it depends primarily on the number of tasks performed. The programming of modern equipment can reduce the costs and time for processing all the holes in parts, while improving the quality of work.

In its design, there may be a device for supplying a special cooling liquid to the surface. These devices are attached to drilling machines during the processing of rigid materials, which is done to avoid damage and overheating of the tool. The main technical characteristics of the equipment are the machine power, the maximum drilling size, the possible depth of the hole, the spindle stroke along with its speed, the overall dimensions of the table and workpiece, the dimensions and weight of the whole machine, the spindle cone.
