2M55 Radial Drilling Machine: Technical Specifications

Radial-drilling is a special type of machine tools that can be found both in large-scale and small-scale production enterprises. This type of equipment is currently the most popular in the industry. One of the most common models of this group is today 2 M55. Radial drilling machine is very productive, reliable and durable.

Design features

What specific characteristics of the 2M55 machines differ, we will consider a little below. To begin with, let's figure out what radial-drilling units are. Such machines belong to the group of machines of a universal type. Their main design features are:

• large spindle speed range;

• the presence of an automatic shutdown mechanism when a specified drilling depth is reached.

Some types of radial drilling equipment may have other design features that increase ease of use. In any case, the box of speeds and working gears in such machines is located in the drill head. Accordingly, all the main nodes in the equipment of this type are located here.

The main structural elements 2M55

The actual layout of the 2M55 radial drilling machine includes the following large nodes:

• foundation ;

• a column ;

• drilling head ;

• traver su .

The base of the unit serves to fix the workpieces.

Modern industry produces radial drilling machines of various layouts:

• stationary desktop;

• with a column moving along the surface of the workpiece;

• large machines moving on rails;

• mounted directly on the workpiece itself near the work surface.

Model 2M55 refers to the first type of equipment. The layout of the machine part, it has a two-column. This design gives the operator a lot of advantages during operation. The fact is that on type machines it is not possible to offset the spindle when clamping the column. That is, the design of the unit is obtained as rigid as possible. This, in turn, among other things, allows you to process workpieces very high quality.

The clamp at the column of the 2M55 radial drilling machine (a drawing of it with the indication of the elements is presented below) is provided for hydraulic. It is located in the gear housing of the sleeve lifting mechanism.

The drilling headstock of the 2M 55 radial drilling machine consists of gearboxes and gearboxes. The working tool in such equipment rotates from an electric motor. It is installed, as in all other types of machines, in the spindle. The landing hole of the latter has a conical shape.

Scope of use

Most often, 2M55 radial drilling machines (photos of these units are presented on the page) can be seen in the shops of metallurgy enterprises. They are used in most cases for working with large parts. For the same purpose, similar equipment is often used in enterprises of heavy engineering, shipbuilding and aircraft manufacturing. Such machines cost, in spite of the fact that they are essentially obsolete, quite expensive models and at the same time they differ in large dimensions and weight. An enterprise can buy a used unit 2M55 at a price of 150 thousand rubles. The figure is, of course, quite large. However, the price of modern new models of radial drilling machines can reach up to a million or more. Therefore, as an economical variety of such equipment, the 2M55 fits very well.

What work can be done

2M5 5 radial drilling machines can be used for:

• creating holes (not only in metal, but also in wood or plastic);

• countersinks and reaming;

• grinding surfaces;

• creating threads inside the holes.

This type of equipment is intended for both roughing and finishing of internal conical, cylindrical, threaded or end surfaces. The working tools on such machines can be used as follows:

• drill;

• taps;

• sweep.

Also, in some cases, various kinds of special tools can be used.

Main technical characteristics of the 2M55 radial drilling machine

It is this model that is currently used most often in enterprises. 2M55 equipment is used , as already mentioned, mainly for processing large parts. Therefore, one of the features of the model, like most other radial-drilling, is high power. Processing of blanks on such a machine can be carried out at 19 different speeds. Use of such equipment is allowed for different materials. However, most often metal workpieces are still machined on radial drilling machines. The largest drilling diameter in 2M55 units on steel products of medium hardness is 50 mm.

Other characteristics of 2M55

In operation, the 2M55 radial drilling machine, the description of which was given above, as you can see, is quite convenient. This is primarily determined, of course, by its excellent technical characteristics.

The technical characteristics of the 2M55 radial drilling machine are thus very good. This model is also equipped with a control system that makes it easy to automate any operation that is performed.

It is delivered, of course, complete with a radial drilling machine 2M55 and a passport. You can find out more about the characteristics of the unit from this document. Also with the passport there is an instruction manual for this equipment and safety rules when working on it.

Model benefits

In comparison with previously released modifications, the 2M55 machine has the following advantages:

• the presence of a developed cone that allows you to work at high cutting conditions ;

• increased sleeve travel along the column;

• the speed of movement of the clamp and sleeve (reduces the time of reinstallation);

• excellent maintainability;

• the absence of various kinds of mechanisms on the upper end (provides ease of use).

Manufacturer

Since Soviet times, the 2M55 model is produced by the Odessa Radial Drilling Machine Plant. This enterprise was founded back in the century before last - in 1884. In Soviet times, it was called the Lenin Engineering Plant. This company began producing machines in 1928.

The first radial-drilling unit, designed to make holes with a diameter of up to 50 mm, was manufactured by the plant in 1946 - immediately after the war. In addition to the popular 2M55 model, this company supplies to the Russian and Ukrainian markets such high-quality units well known to many manufacturers as 2A55, 2H55, 2A554, etc. Some machines of this manufacturer are designed for drilling holes up to 75 or even 100 mm in diameter. Any machines of the Odessa plant are considered by consumers as products of very high quality and reliable. This concerns, of course, and the 2M55 model.

2M55 CNC Radial Drilling Equipment

To increase the productivity of units of this brand to improve the quality of machining parts at metallurgical enterprises and machine-building plants, in addition to them, CNC can be used. In versions with CNC (for example, machine 2M55F2) the software is usually laid on moving along three axes, the tool number and on the parameters of the processing mode. The workpiece in this case can be installed on a table-plate or on the foundation of the unit. The operator changes the tools manually.

To ensure the smooth operation of the 2M55 CNC radial drilling machine , a rack for 18 tools is usually installed next to it. Each cell of the latter is equipped with a light signaling the sequence of installation in the spindle. Switches are mounted here to control how tools are used.

Modern modifications

The 2M55 model, as already mentioned, was developed back in Soviet times. Then this unit was considered innovative equipment. Reliable and hardy 2M55 is also considered by modern manufacturers. These machines rarely break. It’s very convenient to work with them. But nevertheless, this aggregate, of course, is inferior in many respects to modern radial drilling machines. Modification 2M55 and the addition of CNCs can significantly increase its productivity and improve the quality of workpiece processing. However, enterprises acquire such machines for the most part only if they want to save some money.

If the priority task of the plant is to produce high-quality parts in large quantities, its management should, of course, pay attention to more modern types of radial drilling equipment. Such modifications 2M55 include, for example, machines:

• 2C550;

• 2K550;

• AC2550.

Their technical characteristics, for comparison with the 2M55 radial drilling machine , are presented in the table.

Is it released today

Despite the fact that recently, engineers have developed new, more advanced modifications of the 2M55 machine, its production continues today. Many companies supply this equipment to the market and it will not be difficult to purchase it if necessary. In most cases, the manufacturer of these units gives a guarantee for their products for 12 months. If necessary, enterprises can upgrade the 2M55 machine at almost any plant that produces radial drilling equipment.
