DRILLING MACHINES

Drilling machines which are used mainly for drilling holes in machine parts, are made in many different types designed for handling the various classes of work.

The upright drilling machines is the type mostly used, and the name applied to this class indicates that the general design of the machine is vertical, and also that the drill spindle is in a vertical position.

The radial drilling machine. — The main advantage of a radial machine is that the drill can be moved over the work to any desired position, so that a large number of holes can be drilled in the work without moving it.

The sensitive drill is a small machine of light construction, which possesses sensitive qualities which are of value in drilling holes in delicate work.

The multiple-spindle type is built in both vertical and horizontal design.

It can perform a number of operations on a component without the necessity of changing tools.

Gang Drills. — When a number of single-spindle drilling machines columns are placed side by side on a common base and have a common work table, the machine is known as a gang drill. Each spindle is independently controlled as to speed and feed so that a number of operations may be performed in succession and simultaneously upon the machine. In this machine work is moved progressively from one spindle to the next.

ВАРИАНТ № 13

I. Прочитайте и переведите тексты:

THE SHAPER

A shaper is a machine that forms surfaces by successive reciprocating cuts of a tool over the work. The work is stationary with the reference to the tool but moves laterally in small steps so that the successive cuts can be made. Although most of the work performed on shapers consists of plane horizontal surfaces, it is also possible to finish vertical and angular surfaces, and, with the proper tools and accessories, even curved surfaces may be machined.

The size of a shaper is determined by the longest stroke of the ram.

Shapers are driven by belt from a countershaft, by direct connected motor, or by hydraulic power.

THE PLANER

Planers are essentially for machining plane surfaces which are larger than can be cut or reached on the shaper. The modern planer with modern electric controls has a high output.

The planer has a reciprocating table which travels beneath a cross bar on which the tools heads are mounted. Normally one or two tool heads are mounted on the cross bar, but additional tools, generally for cutting vertical faces, may be mounted on the columns supporting the cross bar. The usual design shown in Figure comprises two vertical columns between which the table reciprocates. The cross bar is so mounted that it can slide vertically on these columns. All motions for feed or cut take place either by dropping the cross bar, moving the tool head across the cross bar, or lowering the tool holder mounted on the tool head. The first two of these motions are generally power or hand- operated but the last is often hand-operated only.

The table is normally operated by some form of rack-and-pinion or spiral drive.

Modern high-speed planers are now fully electrified.

4) основные инструменты 9) движется под поперечиной
5) с помощью гидравлической силы 10) стол движется взад и вперед
