At the enterprises are used lathesseveral types. They can be designed to perform a variety of work related to the processing of blanks of metal and wood. One of the most popular types of this equipment are vertical turning lathes.
This type of machine is designed forprocessing of products with large weight and diameter and a slight height. It can be, for example, various kinds of gears, flywheels, etc. Turning work on such equipment can be performed with blanks with a diameter of up to 2.5 m. There are several types of such machines, slightly different in design and performance characteristics.
The first equipment of this typeclassified into single and double post. The second variety is used for processing workpieces of very large diameters. In the construction of this type of machine, among other things, an additional cutting upper support with horizontal feed is provided. Cutting tools in a two-post machine are mounted in the tool holders of the side and top supports, as well as in the sockets of the turret. On the frame of such a unit there are two racks connected by a crossbar. The latter carries two calipers. The crossbar moves along the racks.
Single Column Turning Lathe Cancan only be used for work with workpieces with a diameter of up to 1.25 m. This equipment is different in that it includes a vertical caliper with a turret and a side caliper equipped with a tool holder on a vertical feed. The diameter of the table of such a unit does not exceed 1.6 m.
Also lathe turning machinesclassified into automatic and semi-automatic. On the equipment of the first type, products are made either from rods or from piece blanks. On semiautomatic machines process only the bar. Of course, just like a machine of any other type, the carousel can be supplemented by CNC.
The main components and mechanisms of the turret lathe are:
table, also called faceplate;
racks;
calipers;
traverses.
These machines can be equipped with calipers.several varieties. Revolving are intended for processing of preparations outside. Boring calipers are used for cutting grooves in products, as well as, respectively, for boring. Lateral knots of this type are also applied to processing external surfaces of preparations. Most often they are used for grooving and chamfering.
Turning works on such a unit are performed onthe basis of the three types of movement: movement of the traverse and calipers, as well as the rotation of the table. At the same time, standard rotary, high-precision and heavy rotary machines can be used in production.
If desired, the carousel lathe caninstall third-party components and mechanisms that enhance its functionality. Such elements include, for example, various grinding and milling devices. In addition, when using additional nodes on this type of equipment, slotting can be performed.
Carousel lathes can be usedfor the manufacture of various products. Therefore, they are used in enterprises of many specializations. Very often, such machines are installed in the shops of factories in such areas of the national economy as engineering. This equipment is used in the production of hydroelectric power plants, the assembly of nuclear power plants, etc. In addition to the actual turning of parts, on rotary machines you can perform such operations as:
drilling;
boring;
eruption of annular grooves;
turning cylindrical and conical surfaces;
deployment;
countersinking, etc.
Функционируют станки карусельные токарные по simple principle. The workpiece is mounted on the table in a horizontal position by means of special cams. The main movement during the work is the rotation of the table itself. The auxiliary ones include the movement of the turret, the movement of the crosspiece in a vertical position, etc. The workpiece on this type of machine can be simultaneously processed from several sides at once.
Modern industrial equipment of this typecompared with the usual has a number of undeniable advantages. To these can be attributed primarily high performance, as well as the accuracy of machining. It is a special type of CNC computer with software installed on it. Processing of parts in this case is made according to the drawings developed by engineers. They are compiled in special graphics software.
Precisely such machines nowused in enterprises of the national economy most often. With their use by increasing the quantity and quality of machined parts, production can be made as profitable as possible.
Facilitates the work of the use of suchequipment and specialist turners. All that is required from the operator of such a machine is to monitor the uninterrupted operation of his work and the quality of the tools coming out from under the cutter. It is possible to use such machines for processing parts, including on weekends, as well as on holidays. Indeed, in this case only one operator can monitor the work of several units at once.
Model 1512 is one of the mostproductive and reliable, and therefore widely used in enterprises of different industries. There are several modifications of this single rack machine that differ in design. In many cases, these units can be supplemented by CNC.
The scheme of the turning-and-boring lathe of the basic model 1512 is presented to your attention below. The main features of this unit include:
faceplate diameter 1112 mm;
possibility of processing blanks with a diameter of up to 1.25 m;
18 table speeds;
power of 30 kW.
One of the most popular varieties of this unit is 1512F3. This model is usually complemented by CNC.
From the base model, this unit is different beforeall the lack of a side caliper. Designed machine 1512F3 for processing particularly complex parts. That is why it is often upgraded with numerical software. It can be used to work with blanks from ferrous and non-ferrous metals. The characteristics of the CNC turning lathe 1512F3 have the following:
maximum billet diameter - 1.25 m;
maximum height of the workpiece - 1 m;
limits of table rotation frequencies - 1.6 / 315 rpm;
main motor power - 70 kW;
dimensions - 4050х4590х5400;
weight - 17,000 kg.
Thus, the carousel lathe -the equipment is productive, reliable and very demanded. With its use you can make a variety of parts, often very complex configuration. In this case, especially high-quality products are obtained, processed on the units of this type, equipped with CNC.
