DRILLING

Drilling is a type of mechanical treatment with a bore. Virtually any item in a composite structure has openings for durable and reliable fastening of elements. Use of different bores allows to produce holes varying in diameter and depth.

Drilling is the rotational movement of a bore and the feed is the longitudinal movement of a bore or of a workpiece. In our company we use various equipment for drilling: from simple drills to automatic drilling machines.

Types of drilling works:

drilling cylindrical holes;
drilling oval holes;
drilling multifaceted holes;
reaming (increasing diameter).

Equipment for drilling works

Drilling cylindrical and multifaceted holes is made by means of differing in size bores. Basic materials for bores:
carbon steel (for soft metals)
low-alloy steels with higher heat resistance (for soft metals and alloys)
high-speed steels (for metals in non-hardened state)
bores with carbide tip (for non-hardened steels, non-ferrous alloys at high speeds)
bores with borazon (for hardened steels, cast iron, non-ferrous metals);
diamond bores (for solids).

Depending on the design and the location of the spindle drilling machines can be divided into three main classes:

single spindle for vertical drilling. Allows to get the holes with a diameter up to 75 mm. They are also suitable for boring, reaming, countersinking, threading.
Desktop drills. They are used for making holes in small details
Radial drilling machines. Essential for boring holes in large parts that are difficult to move to the spindle
