Murray JoeAll types of drilling machines can be divided into vertical drilling, horizontal drilling, radial drilling, coordinate boring, diamond boring, single-spindle, multi-spindle. Let’s look at these types of machines and their types in more detail.
Vertical drilling machines are the most common variant of drilling stationary equipment. Equipment modifications and types of work performed on such machines are quite diverse. The devices were named by the principle of spindle movement: the spindle headstock is lowered to the workpiece and performs vertical drilling. This type of drilling machine allows working with high accuracy of making blind and through holes.
They are convenient for use in home workshops because of their compact size. Machines are used for making holes of small depth and diameter.
Bench-mounted vertical machines allow adjustment of the spindle speed, which is regulated by casting the belt on pulleys with different diameters.
There is a variety of types of tabletop drilling machines, and some models have the ability to supply coolant.
The floor type of vertical drilling machines is equipped with a longer column, so for work closer to the working part there is a table for placing and fixing the workpiece. The table may also have grooves on it, as with the smaller machine models. Separately, a vise can be installed on the machine.
Since these units have a powerful motor, it is mounted separately on the column below or opposite the head.
All kinds of work on drilling machines with long and elongated parts is easier to perform on devices with a horizontal stroke of the spindle and moving along the base table. They are perfect for making axles, shafts, masts, beams. Such machines are also convenient for deep drilling, milling, countersinking and securing large workpieces.
A special type of drilling equipment are radial drilling machines. They are also distinguished by the vertical stroke of the spindle, fixed solid base and column, but the guide in such devices can rotate with respect to the base by 360 degrees.
Coordinate boring machines
These are various sizes of equipment. The size of the machine depends on the diameter of the boring spindle, the larger the diameter, the more massive the machine. One- and two-post axis boring machines move both the table with the workpiece and the spindle with the tool.
Diamond boring machines
The types of diamond boring machine tools are distinguished by their hardness. Machining with such a tool gives the milled hole maximum smoothness. The equipment itself, as well as diamond tooling, is used in manufacturing for precision work in the manufacture of car and aircraft engines, parts for pumps and machine tools.
