2. Jackhammer - Wikipedia

   en.wikipedia.org/wiki/Jackhammer

   A compressor for running a pneumatic jackhammer. A pneumatic jackhammer, also known as a pneumatic drill or pneumatic hammer, [20] is a jackhammer that uses compressed air as the power source. The air supply usually comes from a portable air compressor driven by a diesel engine. Reciprocating compressors were formerly used.

3. Chuck (engineering) - Wikipedia

   en.wikipedia.org/wiki/Chuck_(engineering)

   Methods: heating (via heat guns, blow torches, or ovens) and cooling (via kitchen freezers, winter weather, or decompression of compressed air or nitrogen). A drill chuck may have a hollow body that threads directly onto a lathe's threaded spindle nose. (These are fairly rare, especially nowadays.)

4. Air bearing - Wikipedia

   en.wikipedia.org/wiki/Air_bearing

   When placing the air bearing with the sensor chip, they must not touch the wafer surface being measured. As for the up-and-down movement, a pneumatic piston is used which is, for repeatability reasons, also air-guided. The preload of the air bearing and thus the gap height are also adjusted with this piston. Chuck with integrated lift drive

5. Pneumatic tool - Wikipedia

   en.wikipedia.org/wiki/Pneumatic_tool

   A pneumatic tool, air tool, air-powered tool or pneumatic-powered tool is a type of power tool, driven by compressed air supplied by an air compressor. Pneumatic tools can also be driven by compressed carbon dioxide (CO 2 ) stored in small cylinders allowing for portability.

6. Compressed air - Wikipedia

   en.wikipedia.org/wiki/Compressed_air

   An early major application of compressed air was in the drilling of the Mont Cenis Tunnel in Italy and France in 1861, where a 600 kPa (87 psi) compressed air plant provided power to pneumatic drills, increasing productivity greatly over previous manual drilling methods. Compressed-air drills were applied at mines in the United States in the 1870s.

7. Air compressor - Wikipedia

   en.wikipedia.org/wiki/Air_compressor

   Air compressor supplies air into a nail gun.. An air compressor is a machine that takes ambient air from the surroundings and discharges it at a higher pressure. It is an application of a gas compressor and a pneumatic device that converts mechanical power (from an electric motor, diesel or gasoline engine, etc.) into potential energy stored in compressed air, which has many uses.
