The enterprises use several types of lathes. They can be designed to perform a variety of work related to the processing of workpieces made of metal and wood. One of the most popular types of this equipment are rotary turning machines.
general description
A machine of this variety is intended for processing products having a large weight and diameter and low height. This can be, for example, various kinds of gears, flywheels, etc. Turning work on such equipment can be performed with workpieces with a diameter of up to 2.5 m. There are several varieties of such machines that differ slightly in design and operational characteristics.
Types of Carousel Lathes
First of all, equipment of this type is classified into one-rack and two-rack. The second variety is used for processing workpieces of very large diameters. In the design of this type of machine, among other things, an additional cutter upper support with horizontal feed is provided. Cutting tools in a two-column machine are mounted in the tool holders of the side and upper calipers, as well as in the sockets of the turret. On the bed of such an aggregate there are two racks connected by a crossbar. The latter carries two calipers. The crossbar moves along the guide racks.
A single-column turning and rotary machine can only be used for workpieces with a diameter of up to 1.25 m. This equipment is distinguished by the fact that its design includes a vertical caliper with a turret and a side caliper equipped with a vertical feed tool holder. The diameter of the table of such an aggregate does not exceed 1.6 m.
Also, carousel turning machines are classified into automatic machines and semi-automatic machines. On the equipment of the first type, products are made either from rods or from piece blanks. On semiautomatic machines, only the bar is processed. Of course, like any other type of machine, the carousel can be supplemented by CNC.
Design features
The main components and mechanisms of a turret lathe are:
Such machines can be equipped with calipers of several varieties. Revolvers are designed for processing workpieces from the outside. Boring calipers are used for grooving in products, as well as, respectively, for boring. Side nodes of this type are also used for machining the outer surfaces of workpieces. Most often they are used for grooving and chamfering.
Turning work on such an aggregate is carried out on the basis of three types of movement: moving the beam and calipers, and also rotating the table. At the same time, standard rotary, high-precision and heavy machine tools can be used in production.
Additional items
If desired, third-party components and mechanisms that increase its functionality can be installed on the carousel lathe. Such elements include, for example, various kinds of grinding and milling devices. In addition, when using additional nodes on equipment of this type, it is possible to chisel.
Application
Carousel turning machines can be used for the manufacture of a wide variety of products. Therefore, they are used in enterprises of many specializations. Very often, such machines are installed in the shops of factories in such a sphere of the national economy as mechanical engineering. This equipment is used in the production of hydroelectric power plants, the assembly of nuclear power plants, etc. In addition to actually turning parts, rotary machines can perform operations such as:
Principle of operation
Carousel turning machines operate according to a simple principle. The workpiece is mounted on the table in a horizontal position by means of special cams. The main movement when working is the rotation of the table itself. Auxiliary include the movement of the turret, the movement of the cross member in a vertical position, etc. The workpiece on a machine of this type can be simultaneously processed from several sides at once.
CNC rotary machines
Modern industrial equipment of this type in comparison with conventional has a number of indisputable advantages. These include, first and foremost, high performance indicators, as well as precision machining of parts. It is a special type of CNC computer with software installed on it. Processing of parts in this case is carried out according to drawings developed by engineers. They are compiled in special graphics software.
It is such machines that are currently used most often in enterprises of the national economy. With their use, by increasing the quantity and quality of machined parts, it is possible to make production as cost-effective as possible.
The use of such equipment to turners also facilitates the work. All that is required from the operator of such a machine is to monitor the uninterrupted operation of the machine and the quality of tools coming out from under the cutter. You can use such machines for processing parts, including on weekends and on holidays. Indeed, in this case, only one operator can monitor the operation of several units at once.
Turning and rotary machine 1512
Model 1512 is one of the most productive and reliable, and therefore is widely used in enterprises of various industries. There are several modifications of this single-column machine, differing in design. In many cases, these units can be supplemented by CNC.
The layout of the rotary lathe of the base model 1512 is presented to your attention below. The main features of this unit include:
One of the most popular varieties of this unit is 1512F3. This model is usually complemented by a CNC.
1512F3 CNC rotary machine: technical specifications
This unit differs from the base model primarily in the absence of a side support. The machine 1512F3 is intended for processing particularly complex parts. That is why it is often equipped with numerical software. You can use it to work with workpieces from both ferrous metals and non-ferrous. Characteristics of the CNC turning machine 1512F3 has the following:
the maximum diameter of the workpiece is 1.25 m;
maximum height of the workpiece - 1 m;
limits of table rotation frequencies - 1.6 / 315 rpm;
power of the main electric motor - 70 kW;
dimensions - 4050x4590x5400;
weight - 17,000 kg.
Thus, a carousel lathe is a productive, reliable and very popular equipment. Using it, you can make a variety of parts, often of very complex configurations. Moreover, especially high-quality products are obtained that are processed on units of this type equipped with CNC.
