CNC milling machine 1212 buy. CNC milling machine LTT М1212 (BL-M1212). Designation of milling machines

The main competitor in the sales of universal JET machines in Russia is still old, used Soviet-made machines that appear on the secondary market after sales by enterprises trying to get rid of ballast, carrying out technical re-equipment, or for some other reason. If we are talking about re-equipment of production, then they usually try to order machines from the ones already available at the enterprise, simply by rewriting the names. But today, many machines are no longer produced due to their removal from production or reprofiling of the manufacturer. But the classic universal equipment is fundamentally interchangeable and identical in its functionality, and with the right selection it can be successfully replaced by a machine from another manufacturer and differ only in the color of the frame and the ergonomics (location) of some handles. We bring to your attention several comparative tables of correspondence between the most common Russian (Soviet) metal-cutting machines and their counterparts from the JET company. For reasons of the format of the publication, we do not indicate the full technical characteristics, but only those that determine the functionality of the equipment. Compared machines are comparable in terms of technical parameters and cost.

It is possible to select machines similar in their technical characteristics for most universal machines.

If the task is to re-equip production, replace single models of machines or to select equipment with similar technical characteristics of machines used in the enterprise, you can send a list of the equipment you are interested in to the JET representative office. Our engineers will be happy to select machines of comparable technical characteristics and capabilities from the range of equipment offered by JET and justify their choice.

Milling machines are designed for processing external and internal flat, shaped surfaces, ledges, grooves, straight and helical grooves, splines on shafts, cutting gears, etc.

The designs of milling machines are diverse. In general, milling machines can be divided into two main groups:

• general purpose or universal milling machines (vertical milling, horizontal milling, longitudinal milling
• specialized and special milling machines (slotted milling, keyway milling, carousel milling, copy milling, etc.)

The main shaping movements of milling machines are the rotation of the cutter (the main movement) and the feed motion, which is reported to the workpiece or cutter.

The drives of the main movement and feed are performed separately. Auxiliary movements associated with the supply and withdrawal of the workpiece to the tool are mechanized and carried out from the drive of rapid movements.

The main elements of the mechanisms of machine tools are unified.

The main parameter characterizing general purpose milling machines is the size of the working surface of the table.

According to their design features, these machines are divided into:

• console machines (the table is located on a lifting bracket-console)
• consoleless machines (the table is moved on a fixed frame in the longitudinal and transverse directions)
• continuous action machines (carousel and drum)

• a - universal cantilever horizontal milling machine
• b - wide-universal cantilever horizontal milling machine
• c - wide-universal consoleless milling machine
• g - cantilever vertical milling machine
• d - consoleless vertical milling machine
• e - consoleless horizontal milling machine
• g - longitudinal milling machine
• h - carousel-milling machine
• and - drum milling machine

Console milling machines most common in single, small- and medium-scale production of rice. 119, a, b, c, d). Console milling machines horizontal and vertical - this is the most common type of machines used for milling work. The console milling machines got their name from the console bracket (console), which moves along the vertical guides of the machine bed and serves as a support for the horizontal movements of the table.

Universal console milling machine(Fig. 119, a) has a horizontal spindle 2 and a retractable trunk 1, on which an earring 3 is installed that supports a mandrel with a cutter, the console 4 moves vertically along the rack guide 5. Slides 6 and a turntable 7 are located on the console.

Horizontal console milling machines(Fig. 119, a) have a horizontally located spindle 2 that does not change its place. The table can move perpendicular to the spindle axis in horizontal and vertical directions. Unlike the Universal Cantilever Milling Machine, the work table does not rotate around a vertical axis.

Widely Universal Cantilever Milling Machine(Fig. 119; b, c) in addition to the horizontal spindle, it has a spindle head 1, which can be rotated on the trunk in two mutually perpendicular directions, so that the spindle with the cutter can be installed at any angle to the table plane and to the workpiece being processed. On the head 1, an overhead head 2 is mounted, designed for drilling, reaming, countersinking, boring and milling.

Vertical console milling machine(Fig. 119, d) has a vertical spindle 3, which is located in the rotary spindle head 2, mounted on the rack 1.

Consoleless vertical milling machines(Fig. 119, e), which are used to process workpieces of large parts, have a sled 2 and a table 3 that move along the guides of the bed 1. The spindle head 5 moves vertically along the guides of the rack 6. The spindle 4 has vertical axial movements when the cutter is installed. The table moves only in the longitudinal and transverse directions.

Consoleless horizontal milling machines(Fig. 119, e), which are used to process workpieces of large-sized parts, have a sled 2 and a table 3 that move along the guides of the frame 1. The spindle head 5 moves vertically along the guides of the rack 6. The spindle 4 has axial movements when installing the cutter.

Longitudinal milling machines(Fig. 119, g) are designed for processing workpieces of large parts. Two vertical posts 6 are installed on the frame 1, connected by a cross member 7. Milling heads 3 with horizontal spindles and a traverse (crossbar) 4 are mounted on the guide posts. Milling heads 5 with vertical spindles are installed on the latter. Table 2 moves along the rails of racks 4.

Carousel-milling machines(Fig. 119, h), designed for surface treatment with end mills, have one or more spindles 3 for finishing and roughing. The spindle head 2 moves along the guides of the rack 1. The table 4, rotating continuously, informs the feed rotation of the workpieces installed on it. A table with a slide 5 has an installation movement along the guides of the frame 6.

Drum milling machines(Fig. 119, i) are used in large-scale and mass production. The blanks are mounted on a rotating drum 2 having a feed motion. Milling heads 3 (for roughing) and 1 (for finishing) move along the guide rails 4.

Console milling machines

Console milling machines are the most common type of machines used for milling work. The console milling machines got their name from the console bracket (console), which moves along the vertical guides of the machine bed and serves as a support for the horizontal movements of the table.

The presence of the console, giving console milling machines a number of conveniences during maintenance, somewhat reduces the rigidity at the junction with the bed, therefore, in the designs of modern machines, the length of the console guides is significantly increased, devices for fixing the moving parts of the machine are created, and the rigidity of body parts is increased.

Since for the most part the parts used in mechanical engineering fit into the dimensions of general-purpose console milling machines, the fleet of milling machines in mechanical workshops is mainly equipped with horizontal and vertical milling machines of the console type, and the fleet of tool and mechanical repair shops, in addition, also universal-milling and wide-universal-milling.

In addition, modifications are produced on the basis of some basic models. For example, on the basis of vertical milling machines 6M12P and 6M13P, high-speed cantilever vertical milling machines 6M12G1B and 6M13PB are produced. On the basis of the horizontal milling machine 6M82G, a more high-speed model of the machine 6M82GB is produced. On the basis of universal milling machines 6N81 and 6N82, universal milling machines 6N81A and 6M82Sh are produced. Wide-purpose milling machines are currently widely used in single and small-scale production for a variety of milling, boring and drilling operations. On these machines, you can produce metal models, die-forms, templates, cams, etc.

The 6H81A wide universal machine has a spindle head located on the trunk and rotating around the horizontal axis from 0 to 115 °. In the horizontal position of the head, the machine works like a horizontal milling machine, and in a vertical position, like a vertical milling machine.

The 6M82Sh wide-purpose machine and the 6M83Sh larger machine similar in design have two spindles: one is horizontal, like a conventional horizontal milling machine, the second is located on the trunk and can be installed at any required angle. The use of a dividing head and a round rotary table greatly expands the scope of these machines. For processing various kinds of surfaces, as well as large-sized workpieces larger than the table area, the vertical headstock is mounted on a retractable trunk and can be rotated at any angle in two mutually perpendicular planes. Simultaneous operation of horizontal and vertical spindles is possible.

Standard sizes of console milling machines It is customary to characterize by the size of the working (fixing) surface of the table. Console milling machines can have horizontal, universal (wide universal) and vertical execution with the same size of the working surface of the table. The combination of different versions of the machine with the same basic dimensional characteristic of the table is called size range of machines.

In the USSR, the production of console milling machines of five sizes was mastered:
No. 0; No. 1; No. 2; No. 3 and No. 4, and for each size a full range of machines was produced - horizontal, universal and vertical. Each machine of the same size range had the same designation in the cipher, corresponding to the size of the working surface of the table.

Depending on the size of the working surface of the table, the following sizes of console milling machines are distinguished:

Size	Range of machines	Table size, mm
0	6R10, 6R80, 6R80G, 6R80Sh	200 x 800
1	6N11, 6N81, 6N81G; 6R11, 6R81, 6R81G, 6R81Sh	250 x 1000
2	6M12P, 6M82, 6M82G; 6P12, 6P82, 6P82Sh; 6T12, 6T82, 6T82G, 6T82Sh	320 x 1250
3	6M13P, 6M83, 6M83G; 6P13, 6P83; 6T13, 6T83, 6T83G	400 x 1600
4	6M14P, 6M84, 6M84G	500 x 2000

In accordance with the dimensions of the table, the overall dimensions of the machine itself and its main components (bed, table, sled, console, trunk), the power of the electric motor and the magnitude of the greatest movement (stroke) of the table in the longitudinal direction, the sled in the transverse direction and the console in vertical directions change.
