The bed of a lathe machine is the base on which all other parts of lathe are mounted. It is massive and rigid single piece casting made to support other active parts of lathe. On left end of the bed, head stock of lathe machine is located while on right side tail stock is located. The carriage of the machine rests over the bed and slides on it.

Working or Operating Principle of DC Motor | Electrical4U

The very basic construction of a DC motor contains a current carrying armature, connected to the supply end through commutator segments and brushes. The armature is placed in between north pole and south pole of a permanent or an electromagnet as shown in the diagram above.

A principle of construction of an integrated machine

The problems arising in the automation of multiproduct small batch production in mechanical engineering due to necessity to ensure its high flexibility are indicated. It is shown that the automation level of such a production can be effectively increased by the organization of a group production and the part orientation of equipment. In so doing it is useful to group parts on the basis of ...

AC Generator - Principle, Construction, Working Principle

Alternators are generally high current and high voltage machines. The stationary armature-rotating field construction has many advantages. A few of them include: 1) The current is drawn directly from fixed terminals on the stator without the use of brush contacts. 2) The insulation of stationary armature winding is easier.

4 PRINCIPLES OF OPERATION OF SYNCHRONOUS MACHINES Magnets always have two poles: one called north; the other called south. Two north poles always repel each other, as do two south poles. However, north and south poles always attract each other. A magnetic field is defined as a physical field established between to poles.

What Is Soil Nail Wall Construction?

Oct 17, 2018 · The construction procedure starts, drilling into the soil, where the nail, steel bar, is going to be placed. After the drilling has been completed, exact depth must be provided by the geotechnical engineer, the nail must be inserted into the drilled hole. Then, it must be grouted into the soil to create a structure similar to a gravity wall.
