Andy, the use of those length units depends on the circle who uses them. Woodworkers use cm, metalworkers mm, opticians micrometers, nuclear scientists nanometers. The aim is to leave off unused zeroes, either in front or after the decimal point. Hectoliters are the most important measure of

Chris, just think of the radioactive people like the Curies and Bequerel (rad. activity),  Gray (energy dosis), Sievert (man-equivalent dosis). Then there was Georg Ohm for el. resistance and, for what his name is read "Mho" backwards in the US, Siemens for conductivity. Then, most important,

Notice that now-days many of the "standard" SI units are named for long-dead scientests Volt, Ampere, Watt, Henry, Farad, Joule, Hertz, Newton, Pascal, Celsus, Kelvin, Likely a lot more I can't remember. If you know a little history you can remember them. I think that is why they use proper

Most of the pneumatic valves I use have a small actuator (coil) that opens a small air passage to push the thimble within the valve body to the requested position. I recall that they are called "pilot valves". So they use a very small amount of current to do a very big job. I have used Parker

With that thin of a chip it is doing more "rubbing" than "cutting", and with a lot of heat in the chip, it is likely going to start friction welding the chips to the cutter. Things can go downhill very fast, and a broken cutter will result! With the cooling rig that I have, the part often comes

The flow rate of the coolant is adjusted by rotating the nozzle at the end of the flex line. You can even adjust to cut off the coolant flow completely, and just have air flow on the work. --J. Ray Mitchell Jr. jrmitche...@gmail.com (818)324-7573 "No problem can be solved from the same level of

Yes, and Yes. The units Andy sited on EBay look like a similar design to what I have. The key is to keep the bottle a bit lower than the exit plane of the nozzle, so that when the air is shut off, the coolant drains back, not continuing to syphon (dribble) out the nozzle. --J. Ray Mitchell Jr.

What you are making is very much like an artist's air brush, the kind used for very small and detailed work. The amount of air thy use is tiny. Some are controlled with a foot switch and others with a mechanical button on the "brush" The amount of air used is so tiny you can just let the air

Run several misters and you need around 25 PSI to draw the cutting fluid, mist the liquid and blow away the swarf. I don't like my big compressor working hard to produce 25 PSI so I'm busy setting up a small 3 phase motor to run and oilless pump with a small VFD. This way I can set the speed of

Yes, those solder station use an air pumps are not unlike an aquarium air pump. Maybe that is enough, all you need is enough air to cary the mist of atomized droplets. Another place to look is "air brush" pumps. These are designed to power tiny paint guns and to run all day long. They are
