2. Scissors mechanism - Wikipedia

   en.wikipedia.org/wiki/Scissors_mechanism

   This mechanism is used in devices such as lift tables and scissor lifts.Modern low-profile computer keyboards make an extensive use of it as well, installing each key on a scissor support to ensure their smooth vertical movement, allowing the use of a cheap and reliable rubber dome contact set, instead of expensive and complex array of mechanical switches.

3. Drill press - Wikipedia

   en.wikipedia.org/wiki/Drill_press

   Column drill press is a common type characterized by the fact that the drill spindle can be moved up and down axially ("along a column"), and has a height-adjustable table, usually adjustable via a rack and pinion. They often used with a vise holding the workpiece, and the vice is again clamped to the table. The vice has to be moved in order to ...

4. Quill drive - Wikipedia

   en.wikipedia.org/wiki/Quill_drive

   The running gear of a quill drive-equipped EP-3 electric locomotive. A quill drive is a mechanism that allows a drive shaft to shift its position (either axially, radially, or both) relative to its driving shaft. It consists of a hollow driving shaft (the quill) with a driven shaft inside it.

5. Magnetic drilling machine - Wikipedia

   A morse taper 3 arbor equipped magnetic drill machine using taper shank drill bits. The arbor or chuck on a magnetic drill is attached to the motor. It is a type of clamp used to attach the core drills. There are mainly two types of chuck available for the magnetic drill, industrial arbor (manual tightening) and quick change drill chucks.

6. Lift table - Wikipedia

   en.wikipedia.org/wiki/Lift_table

   The most common lift table design incorporates hydraulic cylinders and an electrically powered pump to actuate the scissor lifting mechanism. Lift tables can also be driven by pneumatic sources, trapezoidal-threaded screw drives, push chains or by hydraulic foot pump when the load is not heavy. The choice of drive mechanism depends on factors ...

7. Drill - Wikipedia

A drill press (also known as a pedestal drill, pillar drill, or bench drill) is a style of drill that may be mounted on a stand or bolted to the floor or workbench. Portable models are made, some including a magnetic base.

8. Rotary steerable system - Wikipedia

   en.wikipedia.org/wiki/Rotary_steerable_system

   Push-the-bit tools use pads on the outside of the tool which press against the well bore thereby causing the bit to press on the opposite side causing a direction change. Point-the-bit technologies cause the direction of the bit to change relative to the rest of the tool by bending the main shaft running through it.

9. Elevators (drilling rig) - Wikipedia

   en.wikipedia.org/wiki/Elevators_(drilling_rig)

   To latch around a piece of pipework a set of elevators need a precise internal diameter, with an appropriately profiled shoulder to accommodate the lower profile of a tool joint. The latch mechanism has to prevent opening under radial loads of up to hundreds of tons. For some purposes (casing elevators, and loading pipe into and out of the ...
