Milling machines are taller than lathes, but they also have a shorter length, allowing manufacturing companies to place them in small spaces. Aside from shape and size, though, the primary difference between lathes and milling machines is their method of operation. With lathes, the workpiece rotates against a stationary cutting tool.

Gear pumps use the actions of rotating cogs or gears to transfer fluids. The rotating element develops a liquid seal with the pump casing and creates suction at the pump inlet. Fluid, drawn into the pump, is enclosed within the cavities of its rotating gears and transferred to the discharge. There are two basic designs of gear pump: external ...

The turning gear rotates the turbine shaft and other accessory equipment to make sure that there is uniform cool down of the shaft. Otherwise it can result in sagging or bending of the turbine rotor. During turbine starting also it is first put on the turning gear to break the inertia slowly, if it's a cold start. Continue reading with Quora+

•Two identical ball mills were in place at the plant (1A & 1B). •These machines are used to pulverize or crush lime into small particles (dust) that is then made into a slurry and injected into the flue gases to reduce pollution. Hundreds of steel balls rolling with the slow turning mill act to effectively crush the lime.

The post mill was composed of a four bladed mill mounted onto a central post, which used wooden cog-and-ring gears to covert the motion of the horizontal shaft to vertical motion that turned a grind stone. The wooden cog-and-ring gear was used by Vitruvius, an engineer of the Augustan Age, to develop the first horizontal axis water wheel.

Disadvantages – the lead screw, and the half nuts take extra wear and the fact that SOME lathes that have separate feed screws and lead screws allow you to set the rates separately, and almost ALL have the feed screw running much more slowly, so even if you have the lathe set for a fairly coarse thread, the feed screw is in a "somewhat useful" range.
