machine foot The part for supporting a machine on the ground
machining center A machine, or a set of machines, capable of being configured for a variety of machining operations (milling, turning, drilling, etc); complete with other accessories for protection, monitoring, measuring, etc
magnetic sensor A sensor that gives an electric output in the presence of a magnetic field
magnetic separator A system for separating out ferrous material, as mixtures of materials pass by (in a pipe or on a conveyor belt, for example) using powerful magnets to attract that material
management software Computer software that keeps track of resources, to help in management and decision-making
manual winch A winch, for winding in a cable, for pulling heavy loads, or lifting them up to a pulley, that is turned by hand
marking laser A tool that uses the concentrated energy of a thin laser beam to melt or burn the target substance, thereby leaving a visible mark. The beam is used to trace out letters, numbers or other identification patterns
marking machine A machine that marks the target substance, tracing out a visible letters, numbers or other identification patterns
mass flow-meter Apparatus for measuring the mass flow of a fluid (in a pipe or channel)
mass spectrometer Apparatus for determining the masses of the individual atoms and molecules within the sample , by measuring the deflection of beam of charged ions in the presence of magnetic or electrostatic fields
measurement software Computer software that takes input from sensors in order to compute the value of one (or more) parameters of the object under study
mechanical seal A seal consisting of two highly polished faces, one attached to each part (fixed and rotating). One face is usually hard (such as silicon carbide or tungsten carbide), the other is either also hard, or soft (such as carbon)
melting furnace A chamber for achieving extremely high temperatures, for melting solid substances to their liquid phase
metering pump A pump that pumps a constant volume of fluid at each revolution and hence can be used for metering just by counting the number of revolutions
metering valve A valve for dispensing fluids at a controlled rate
micro-switch An electrical switch needing only a very small displacement between its open and closed positions. Often used for detecting small movements, due to the presence or absence of a mechanical object (a door, a window, a mechanical arm, etc)
micrometer Apparatus for the accurate measurement of small thicknesses and distances
microscope An instrument, usually optical, for magnifying the image of extremely small objects
MIG welder A welding system for performing gas metal arc welding (GMAW), also known as metal inert gas (MIG) or metal active gas (MAG) welding. A continuous and consumable wire electrode, along with a shielding gas, feeds out through the welding gun
milling center A machine, or a set of machines, with a variety of tools for milling, in various set-ups; complete with other accessories for protection, monitoring, measuring, etc
milling cutter The cutting head, usually in the form of a rasped-edged or rasp-faced rotating cylindrical wheel, for cutting into the workpiece
milling machine A machine (typically on the factory floor) using a cutting head, usually in the form of a rasped-edged or rasp-faced rotating cylindrical wheel, for cutting into the workpiece
