Warm-upGuess 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
3.
Welcome to the world of machines!Aim
- learn different types of machine tools
Tasks
- compare machine and hand tools
- learn machine-tools functions
- importance of machine work
4.
Lead-inUnder 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
- 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.

Summary of the lesson30.
Home task1. 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.
31.
Home taskLathe
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
32.
Home taskVocabulary:
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
33.
Home taskAnswer 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?
