TV-7 lathes provide an opportunity for young people to learn about the basic processes of cold metal processing, and then reinforce their knowledge with practical exercises. The device is considered an improved model of the TV-6 machine. The only difference is that there is a different gearbox and headstock.
Speed Lathes TV-7
The speed of the equipment can be switched using a drive belt, which throws to the desired position, and the corresponding box, which has 2 modes of operation. The device does not have any leverage, due to which the speed switching would occur during step-by-step operations.
The main components of the device
The machine consists of the following parts:
- front and rear headstock;
- protective display, casing and additional shields;
- mode switch;
- guitar;
- bed;
- device for lighting;
- thumbs;
- two-speed reduction box;
- apron.
The training lathe TV-7 allows you to perform 5 different actions when turning metal:
- metric thread cutting;
- segment;
- boring and grooving of various shapes;
- drilling;
- cutting of the ends.
Control of lathes TV-7
Lathes TV-7 are considered quite easily controllable equipment. For control, various batch switches are used, a special button, when pressed, all work processes are instantly turned off, a button that starts the rack gear, two flywheels, one of which is used to manually control the movement of the carriage in the longitudinal direction, and with the help of the other, the tailstock moves.
In addition, the TV-7 lathes are made in such a way that they have 5 different handles, namely:
- a handle for starting the screw nuts;
- pintle connection handle;
- handle for fixing the cutting head;
- a handle with which you can determine the rate of the threaded pitch and feeds.
All of the above controls all the processes that are carried out, during which there is a procedure for processing various steel objects that are light in configuration and initial settings. The device of the screw-cutting machine TV-7 fully performs all the functions expected from it. And the fact that modern society does not cause absolutely any difficulties to master its work is a vivid confirmation of this.
Bed and front headstock of TV-7 lathes
Lathes TV-7 are characterized by their main node - the bed, which consists of two pedestals. On it you can see all the details of the device, with the exception of the electric motor. The bed has 4 guides: 2 flat and 2 prismatic. They are made by casting, production material: cast iron. Guides are used to move the tailstock and caliper. The left part of the bed encloses the front headstock. She focuses on the correct rotation of the processed equipment, including supporting him in the right position.
The rotation from the axis enters the initial stage of processing due to the presence of a face plate with a leash in the construction of the machine or with the help of a special cartridge. Parts are located on the gap where the thread of a part of the product is located. They seem to be screwed to the equipment. The axis can be located in the center of the metalworking device when it is necessary to process the workpiece inside it.
Lathes TV-7 - an innovation of our time. They are relevant both among young people and among other age categories of people. The unit has achieved such popularity due to the ease of operation and management. Every day an increasing number of people resort to the use of lathes.
