The technological capabilities of universal metal milling machines can be expanded using a vertical head, a universal head, a universal dividing apparatus, a round dividing table, a slotting head, a device for cutting combs and other devices and accessories
Equipment characteristics
The machine can process vertical and horizontal shaped and screw surfaces, grooves and corners. Milling of parts requiring periodic division or screw movement is performed using special devices.
All main components of the machine are mounted on the frame. Also inside it are a spindle assembly and a gearbox. The console with the feed box moves along vertical guides. A slide with a rotating device moves along the console guides, which carries a longitudinal table and allows the table to be rotated around a vertical axis by 45° in both directions, due to which it can move in a horizontal plane at different angles to the spindle axis. The mandrel with the tool is supported by a trunk with earrings.
Manufacturers produce equipment of different sizes, power and, accordingly, purposes: from desktop metal milling machines to professional high-performance machines for long-term hard work. When choosing and purchasing a universal milling machine, you need to pay attention to its following important characteristics:

Processing of simple surfaces of metal products and structures is usually carried out on universal vertical or horizontal milling machines. This type of equipment is reliable and easy to use, easily coping with semi-finishing and finishing machining of grooves, grooves and planes of simple configuration. At the same time, the machine can be used in the manufacture of products from non-ferrous metals, cast iron, steel and certain types of plastic, in any case guaranteeing high quality products and ideal smoothness of the processed surface.
Technical characteristics and scope of universal metal milling machines
Thanks to their advanced design, modern universal machines can easily cope with a wide range of work operations. Using them, you can process workpieces to size, perform boring, countersinking and drilling of complex workpieces for piece and small-volume production. By adding a rotary table or dividing head to the design, you can arrange the production of shafts, sprockets, gears and other similar elements according to specified dimensions. An impressive list of milling and drilling operations is available through the use of a whole set of cutters - cylindrical, worm, modular, disk, shaped, face and others.
The special design of the drilling and milling head allows milling on inclined surfaces and drilling holes at an angle, in any case guaranteeing high quality and safety of work operations. And thanks to the automatic reverse cycle, you can drill holes to a precisely specified depth, eliminating accidental damage to the product due to violation of the requirements for the configuration and dimensions of the part. There are no restrictions on the type of material for universal milling machines - they process steel, cast iron and plastic with equal ease.
Among other advantages of the equipment, it is worth noting the motorized console. Thanks to this design, it is possible to perform readjustment of the machine in the shortest possible time when using horizontal and vertical spindles, as well as when choosing the height of the working area for a vertical spindle. It is also possible to use two spindles simultaneously in a working cycle, as well as to organize work using an automatic pendulum cycle and a semi-automatic linear cycle.
You can expand the range of options offered by installing a universal dividing table, a slotting head and other accessories.
Thus, several sequential drilling or milling operations can be performed on one equipment at once, saving on the purchase of expensive equipment and its maintenance. This factor largely determined the popularity of universal milling machines, which today find the widest application in enterprises with various production volumes.

Milling machines are a type of equipment used for processing various materials by milling. With its help, operations such as:
- cutting of material;
- cutting grooves;
- production of gears and gears;
- and other operations that essentially require the removal of starting material from the surface of the workpiece.
A striking example of a part made by milling, as mentioned above, is a gear.
When processing a workpiece on a milling machine, the working tool (cutter) rotates, which distinguishes it from a lathe in which the part rotates. A metal milling machine is equipment that allows you to process workpieces from various types of metals and alloys, which is difficult to replace. At Promo you can buy milling machines to work with any size of workpiece: from small milling machines to machines for processing large parts. Any size: from a small machine for home and individual use to large-sized milling cutters for small-scale production.
Vertical milling machine for metal
The most popular in its class is the vertical milling machine. It is named vertical because of the particular location of the spindle. The characteristic differences of this type of equipment are:
- possibility of processing any metals and alloys. Naturally, it is necessary to take into account the strength of the cutting tool.
- standard design to facilitate equipment repair and maintenance;
- due to the relatively simple design, brought to perfection during use, high reliability and unpretentiousness;
- a wide range of processing types: boring, drilling, milling. Moreover, after the introduction of a rotating head, it became possible to manufacture parts with an inclination of up to 45 degrees relative to the plane of the table.
Vertical milling machines for metal can be without a console (without console) or with it (cantilever-milling). The latter are characterized by the presence of a console on which the table is located, moving horizontally and vertically, and also allowing the workpiece to be rotated relative to the processing plane. To ensure high precision and processing speed in mass production, CNC vertical milling machines are provided.
Universal milling machine
Universal milling machines are a development of vertical milling machines. They differ in that they include a rotary table, which allows you to install the workpiece at the required angle to the tool. At the same time, there are its varieties: a universal vertical milling machine and a universal cantilever milling machine. You can buy a universal metal milling machine from Proma.
The presence of an additional head in which another cutter is fixed is a sign of a highly versatile milling machine. Moreover, it can be used both simultaneously with the main one and separately from it. Such machines are indispensable in the manufacture of parts of complex shapes. Some types of such equipment do not have a console panel: instead there is a movable column on which the carriage is movably mounted.
The Promo company delivers machines to any region. New machines have a 12 month warranty.
Universal lathes are distinguished by their functionality, representing one of the most advanced and modern types of machine tools. Machines of this type are designed for industrial use, for small-scale production, performing various types of metalworking in small batches. The main task performed by combined lathes is working with cylindrical workpieces, processing shaped parts, and conical-shaped products. The presented models of universal machines are distinguished by their multi-purpose use, variety of functionality and technical characteristics.
Thanks to its universal design, this technique allows for a wide range of turning operations, milling and drilling. The use of universal machines significantly increases the productivity of the work process and provides significant savings in the time required to manufacture a part or product.
Main features of universal lathes
Unlike standard models, universal turning equipment is a whole multifunctional processing complex. Due to the presence of numerous functionalities, special devices and accessories on this equipment, complex processing of workpieces can be ensured in one working cycle. Generalists are able to perform the necessary technological operations without special equipment. There is no need to reinstall parts or replace tools during operation.
Models of universal machines are used to work with large parts and workpieces, allowing to reduce the number of additional operations and manipulations. According to their technical characteristics and parameters, station wagons are divided into the following types:
universal CNC machines, complex machining centers;
universal turning-screw-cutting mechanisms.
Equipping the models with a CNC system ensures the simultaneous execution of several technological cycles, increasing productivity when manufacturing similar products in large series. The role of the operator in this case is reduced to ensuring control over the work process. Universal screw-cutting lathes have a simpler and more reliable design, making it possible to increase the scale of complex processing of workpieces used in mass production during repair and restoration work. The presence of special devices in the design makes it possible to control the process in a semi-automatic mode and carry out technological operations in a clear sequence with the technical specifications.
Universal metal milling machines are used everywhere for various large metal works. Their advantage is that they have a specific mechanism for performing manual drilling and cutting work. More precisely, all drilling and cutting operations on metal are carried out using a cylindrical and disk cutter.
Moreover, desktop universal portable metal milling machines have the additional ability to attach special milling heads, which are used to carry out drilling and cutting work on metal using vertical milling.
But it is also always possible to use horizontal cutters, which once again emphasizes the entire universality of machines of this type.
1 About widely-universal machines
Widely versatile benchtop milling machines are quite different from all other types of milling machines. As a rule, they are distinguished by an additional spindle head and a range of adjustments along the axis. Widely universal machines have different equipment (relative to conventional machines), which has a lot of additional high-precision tools.
The additional spindle head on a device of this type is installed on the so-called retractable trunk.
This head can be rotated at different angles and along any axis, strictly in 2 mutually perpendicular planes. When working on a machine of this type, you can perform operations with both spindles separately or simultaneously, which is unacceptable in conventional machines.
If a wide-versatile manual make the machine even more universal, then an overhead milling head is additionally installed on its rotating head. Thanks to its use, it becomes possible to use a machine of this type to create technologically complex parts not only by milling, but also by drilling, countersinking and even boring.
Table machines of this type can also be used for copying and milling work. And here it is important to understand that widely-universal non-specific machines are not inferior in efficiency to copy-milling machines in copy-milling work.
Additional equipment for a widely-universal device allows it to be modified so that it becomes narrowly focused (in this case, a copy-milling machine) and is no different from copy-milling machines.
Why then in copy-milling works universal metal cutting machines are rarely used? The fact is that a highly versatile machine and its additional equipment has a huge price due to its wide range of capabilities, while machines designed for copy-milling robots are relatively cheap.
The equipment of widely universal devices is usually more than diverse; the equipment of such a device includes dozens of different additional devices. The machine itself consists of the following parts:
- foundation slab;
- bed;
- device console;
- sled;
- fixing portable table;
- the so-called “trunk”, which has the ability to move along the “X” axis and the “Y” axis;
- shipping with cutter.
Some machines of this type do not have a console, and instead, a special carriage moves along vertical guides, the so-called bed.
This carriage is equipped with horizontal guides for the machine slide, which has a working surface and special “T-shaped” slots that can move along the “X” axis and the “Y” axis.
The wide versatility of this type of machine, as well as its auxiliary tools (additional equipment, modifying devices, and so on) allow it to be used in tool and even experimental shops, both for creating various jigs, dies and molds, and when equipment is needed and tools for other machines.
Simply put, this device is capable of creating tools for other types of machines.
2 Classification of machines
There is a special classification “ENIMS”, which designed to systematize all existing machines. In this classification system, a universal metal milling machine belongs to the sixth group.
Each device of this type has an individual model designation, which is represented by a set of numbers and letters. The first digit in the designation is the number of the group to which this particular machine belongs, the second digit indicates its type.
The third and fourth digits assign the machine its size in the ENIMS classification system. And here it is important to know that if there is a letter between the first number and the second, therefore, the design of the machine is a modification of the original. And if the letter is at the end of the device number, then this letter indicates the design type of modification to the basis of the machine model.
Example: “6Р12Б” is a high-speed model, while “6Р82Ш” is a manual horizontal wide-universal milling machine.
There are also differences between machines according to types and accuracy classes. So “N” means that the device is of normal accuracy, “P” is that the device is of increased accuracy, “B” is high, “A” is extremely high, “C” is ultra-precise.
