  2. Chuck (engineering) - Wikipedia

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

    A pin chuck is a specialized chuck designed to hold small drills (less than 1 mm (0.039 in) in diameter) that could not be held securely in a normal drill chuck. The drill is inserted into the pin chuck and tightened; the pin chuck has a shaft which is then inserted into the larger drill chuck to hold the drill securely.

  3. Collet - Wikipedia

    en.wikipedia.org/wiki/Collet

    Several machine collets (top and centre) and a dismantled pin chuck (below). Generally, a collet chuck, [3] considered as a unit, consists of a tapered receiving sleeve (sometimes integral with the machine spindle), the collet proper (usually made of spring steel) which is inserted into the receiving sleeve, and (often) a cap that screws over the collet, clamping it via another taper.

  4. Drawbar force gauge - Wikipedia

    en.wikipedia.org/wiki/Drawbar_Force_Gauge

    Drawbar force gauges are able to detect broken or weakening components of the drawbar clamping system, can give indications that the unit needs lubrication, detect gripper mis-adjustment, or demonstrate that the incorrect retention knob is being used for the machine. A retention knob is a device screwed into the narrow end of a tool holder ...

  5. Tire changer - Wikipedia

    en.wikipedia.org/wiki/Tire_changer

    The air pressure system consists of 4 components: air hose, air inflation gauge, inflation pedal and manual pressure bleed valve. The air hose is located near the top of the tire changer, and it allows compressed air to travel into the tire. A specialized end is used on the air hose to clamp firmly onto valve stems of the wheels. The air ...

  6. Shear (sheet metal) - Wikipedia

    en.wikipedia.org/wiki/Shear_(sheet_metal)

    An alligator shear, historically known as a lever shear and sometimes as a crocodile shear, is a metal-cutting shear with a hinged jaw, powered by a flywheel or hydraulic cylinder. Alligator shears are generally set up as stand-alone shears; however, there are types for excavators. The jaw size can range from 4 to 36 in (100 to 910 mm) long.

  7. Hydraulic calculation - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_calculation

    Hydraulic calculations indicate that the combination of the two primary components of a water based fire protection system will meet the design objectives to control, suppress, or extinguish a fire: The available water supply is sufficient in flowrate and pressure.

  8. Press brake - Wikipedia

    en.wikipedia.org/wiki/Press_brake

    It forms predetermined bends by clamping the workpiece between a matching top tool and bottom die. [2] Bending process A high-tonnage hydraulic press brake Liwei CNC 2000T 12M Heavy Duty model. Typically, two C-frames form the sides of the press brake, connected to a table at the bottom and on a movable beam at the top.

  9. Hydraulic press - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_press

    The hydraulic press depends on Pascal's principle.The pressure throughout a closed system is constant. One part of the system is a piston acting as a pump, with a modest mechanical force acting on a small cross-sectional area; the other part is a piston with a larger area which generates a correspondingly large mechanical force.
