The workpiece is held in place while it is rotating using a dead centre (not freely rotated, i.e., dead). There may be friction on the dead centre due to the rotation of the workpiece when employed in the stationary position. The pointed end of it is placed touching the other end of the workpiece to avoid an abrupt stop in rotation and reduce friction.

A lathe machine is a machine tool that is used to remove unwanted material from a rotating workpiece in the form of chips. This is accomplished with the use of a tool that traverses across the workpiece and feeds into it.

Electric heaters serve as the foundation for the generation of industrial heat. Almost everything we use on a daily basis, including textiles, cement, steel, computer chips, plastic, and glass, depends on them for energy. The following are some particular industries that demand industrial heat in one way or another:

The left-hand thread is obtained when the tool is moved from the right to the left and vice versa. Thus, the lead screw is responsible for the motion of the carriage. It also allows adjusting the depth of the cut.

The grooving operation involves reducing the external diameter workpiece to a relatively small surface area. It is done to leave a thin margin at the end of a thread or close to a shoulder. The grooving usually consists of three types: Square, Round, and Bevelled.

Industrial heat is basically a thermal energy that is used particularly to prepare or treat materials that are used to make manufactured goods. In the process of generating industrial heat, electrical energy is transformed into heat energy. It functions according to the Joule heating principle, which states that every electric heater’s heating element is an electrical resistor that converts electrical energy into heat energy. The active element in the majority of present-day electric heating devices is Nichrome wire, which is supported by ceramic insulators.

Geothermal process utilize heat from the interior of the Earth to create steam, which is then used to produce electricity. Deep holes in the Earth’s crust are drilled in order to obtain hot water or steam, which is then utilised to drive turbines.

In the solar process, sunlight is focused onto a receiver using mirrors or lenses. They utilize solar thermal power to absorb the heat and make steam. The steam is then used to drive electricity-producing turbines.

Low temperature (up to 400 °C), medium temperature (between 400 and 1,150 °C), and high temperature (above 1,150 °C) are the three broad categories that can be used to describe industrial heat.
