  2. Magnetic drilling machine - Wikipedia

    en.wikipedia.org/wiki/Magnetic_drilling_machine

    A magnetic drilling machine used for drilling perpendicular on a 100 mm thick workpiece of mild steel. A magnetic drilling machine is a portable drilling machine with a magnetic base (either electromagnetic or permanent magnet). It can use twist drill bits, annular cutters, milling cutters, and other rotary cutters. With suitable bits it can ...

  3. Magnetic switchable device - Wikipedia

    en.wikipedia.org/wiki/Magnetic_switchable_device

    A magnetic switchable device (often called a magnetic base) is a magnetic fixture that uses one or more permanent magnets in a configuration that allows the external field to be turned on or off. They are used in many applications including optics , metalworking , lifting , and robotics, to attach items to metal surfaces in a secure but ...

  4. Plasma cutting - Wikipedia

    en.wikipedia.org/wiki/Plasma_cutting

    CNC plasma cutting Plasma cutting performed by an industrial robot. Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma. Typical materials cut with a plasma torch include steel, stainless steel, aluminum, brass and copper, although other conductive metals may be cut as well.

  5. V-block - Wikipedia

    en.wikipedia.org/wiki/V-block

    They consist of a rectangular steel or cast iron block with a 120 degree channel rotated 45-degrees from the sides, forming a V-shaped channel in the top. A small groove is cut in the bottom of the "V". They often come with screw clamps to hold the work. There are also versions with internal magnets for magnetic work-holding.

[3] A: cooling gas tangential flow to the outer quartz tube B: discharge gas flow (usually Ar) C: flow of carrier gas with sample D: induction coil which forms the strong magnetic field inside the torch E: force vectors of the magnetic field F: the plasma torch (the discharge).

  8. Current clamp - Wikipedia

    en.wikipedia.org/wiki/Current_clamp

    A digital clamp meter A multimeter with built-in clamp. Pushing the large button at the bottom opens the lower jaw of the clamp, allowing the clamp to be placed around a conductor. An electrical meter with integral AC current clamp is known as a clamp meter, clamp-on ammeter, tong tester, or colloquially as an amp clamp.

  9. Plasma railgun - Wikipedia

    en.wikipedia.org/wiki/Plasma_railgun

    A plasma railgun is a linear accelerator which, like a projectile railgun, uses two long parallel electrodes to accelerate a "sliding short" armature. However, in a plasma railgun, the armature and ejected projectile consists of plasma, or hot, ionized, gas-like particles, instead of a solid slug of material. Scientific plasma railguns are ...
