Laminations minimize eddy currents, or current flow across the iron parts. This is one method to minimze stray losses.
Cast iron is used as the "material of choice" for many machinery housings or bases because it is extremely stable in its structure. Certainly it is subject to thermal expansion and contraction, but the crystal structure of cast iron makes it "hold its shape" in applications ranging from machines and machine parts to cookware. And in things like a lathe bed, we need the thing to be "the same" every day and all the time so we get accurate, consistent work. Cast iron also suppresses high frequencies generated during machining. Note that the ways (the parts of the bed that the carriage slides on), are hardened and machined to provide lasting and accurate surfaces.
The laminations on the core of a transformer are actually insulated from each other. This means that there is no circuit for current to flow, but since the laminations are stacked in an alternating orientation, there is magnetic coupling. If the core were one piece, or the laminations where allowed to touch each other electrically, there would be current flow, i.e. eddy current flow, because the core would represent a one turn secondary that is shorted. This means low voltage, but high current capacity. This means power loss, and degradation of Q and efficiency in the transformer.
Cold-Rolled Grain Oriented silicon steel. Used in transformer core laminations. whatisCRNO? in transformers
CRGO laminations, or Cold Rolled Grain Oriented laminations, are thin sheets of silicon steel used primarily in the manufacturing of electrical transformers and other magnetic applications. These laminations are processed to have a specific grain orientation, which enhances their magnetic properties and minimizes energy losses during operation. The cold rolling process ensures a smooth surface and precise thickness, making them ideal for high-efficiency electrical devices. Their use contributes to improved performance and reduced energy consumption in electrical systems.
Machine shaper are practically used in shaping materials. The parts of the machine shaper are Ram, Table, Clapper Box, Tool head, Cross rail, Stroke Adjustment, Column, Base and Table supports.
Yes
They use raw material like coal and oil for fuel. The iron sorts like iron and tin, are used to especially making machine parts. Salt is used as an ingredients, and the limestone is used as an important founding element.

The coating on CRGO (Cold Rolled Grain Oriented) laminations is typically referred to as an insulation or dielectric coating. This coating is usually made of organic materials, such as epoxy or varnish, and serves to reduce eddy current losses and prevent electrical shorting between the laminations. It helps enhance the magnetic properties and overall efficiency of the transformer or electrical device in which the CRGO laminations are used.
it is used for making machine parts and other mechanical components

The moving parts of a machine have kinetic energy, which is the energy associated with their motion. This energy is the result of work being done to make the parts move and is typically used to perform mechanical tasks within the machine.
energy used for the machine will get lost as heat .machine parts will get worn out.
because Cast iron is strong heavy crushing machinery.

I think it would a lubricant not a part...
