    venturi vacuum generators are "expensive" to run, they waste a lot of water or air, for a chuck it would make much more sense to have a diaphragm pump (or couple in series for deeper vacuum) and run...

    if it doesn't "make the corner" in time during high feed rates, like not cutting that round chafer at high speed, it means it lacks accel/decel capability due set parameters, lack of power, or trying...

    just a tight lid won't help with evaporation, you'll need to seal it (and allow pressure to build), or you'll lose couple liters of water from it during a day, that water will condensate somewhere -...

    from my personal experience tig welding things using back purge, argon is heavier that air, so to purge the air you'd want really slow flow from the bottom towards the top, high flow will make the...

    I've seen repairs where the wear on the slide ways was too much for the gibs to compensate, and then a strip of sheet stock was added to the back of the gib (glued) to build up required thickness for...

    in the picture one of the X gibs seems to have added brass or bronze strip on it, so seems one of the slide surfaces, maybe if that was part of some repair, maybe something is wrong with the oil...

    the sine wave is being generated by short impulses which in theory can make windings vibrate at other frequencies which wouldn't be there if it was driven from the constant 50/60Hz source, and the...

    TIR on the bottom part of the spindle taper on my machine was about 0.003mm

    0.015 sounds like a good reason to remove the spindle and at least get a hand feel of how it rotates, before it...
