the turret lathe is a form of metalworking lathe that is used for repetitive production of duplicate parts, which by the nature of their cutting process are usually interchangeable.it evolved from earlier lathes with the addition of the turret, which is an indexable toolholder that allows multiple cutting operations to be performed, each with a different cutting tool, in easy, rapid succession .
these machines vary in size between small to medium compared to other rotational machines. vertical rotational molding machines are energy efficient due to their compact heating and cooling chambers. these machines have the same or similar capabilities as the horizontal carousel multi-arm machines, but take up much less space.

history. proposed by swedish engineer johan august brinell in 1900, it was the first widely used and standardised hardness test in engineering and metallurgy.the large size of indentation and possible damage to test-piece limits its usefulness. however, it also had the useful feature that the hardness value divided by two gave the approximate uts in ksi for steels.
the brinell scale / b r . the large size of indentation and possible damage to test-piece limits its usefulness. . 'wolfram' ball indenter was used, as opposed to 'hbs', which means a hardened steel ball. the '10' is the ball diameter in millimeters. the '3000' is the force in kilograms force.
the lap or lapping plate in this machine is 30 cm 12 in in diameter, about the smallest size available commercially. at the other end of the size spectrum, machines with 2.4-to-3.0-metre-diameter 8 to 10 ft plates are not uncommon, and systems with tables 9 m 30 ft in diameter have been constructed. referring to the second picture again .
