Guess the word? It is a mechanical or electrical device designed to perform specific tasks or functions to simplify or automate human activities. A machine tool
Aim - learn different types of machine tools Tasks - compare machine and hand tools - learn machine-tools functions - importance of machine work
Under the conditions of sanctions, our country Russia - doubled the production of machine tools in domestic factories - replaces Western machines with Chinese ones - exports modern tools Lead-in - is developing technological cooperation with friendly countries in the field of machine tool production. The exchange of technological experience is very important for us. Therefore, as future operators, you need to have basic knowledge in English in order to share your experience with foreign colleagues.

play an important role in Russian national economic modernization. Machine tools are used to manufacture other. Machine tools are also called M ost machine-tools are driven nowadays with Materials used in industry are machines metals. computers. "work machines“. Machine tools
1. Ask your mechanic teacher what the most important machine tool is. Make a list of machine tools that are used at your college. 2. Read the text “Lathe” and do the tasks.
Lathe Lather is still the most important machine-tool. It produces parts of circular cross-section by turning the workpiece on its axis and cutting its surface with a sharp stationary tool. The tool may be moved sideways to produce a cylindrical part and moved towards the workpiece to control the depth of cut. Nowadays all lathes are power-driven by electric motors. That allows continuous rotation of the workpiece at a variety of speeds. The modern lathe is driven by means of a headstock supporting a hollow spindle on accurate bearings and carrying either a chuck or a faceplate, to which the workpiece is clamped. The movement of the tool, both along the lathe bed and at right angle to it, can be accurately controlled, so enabling a part to be machined to close tolerances. Modern lathes are often under numerical control.
Vocabulary: stationary – неподвижный, стационарный. sideways – в сторону spindle – шпиндель variety – разнообразие, разновидность headstock – передняя бабка chuck – зажим, патрон faceplate – планшайба lathe bed – станина станка numerical control – числовое управление
Answer the questions: 1. What parts can be made with the lathes? 2. How can the cutting tool be moved on the lathe? 3. How is the workpiece clamped in the lathe? 4. Can we change the speeds of workpiece rotation in the lathe? Why? 5. By what means is the modern lathe driven?
