    hexagon symbol on a drawing

    hi all, i recently received a drawing of a part that had a hexagon shape , the guy who made this drawing used a symbol to indicate that this is a hexagon, you can see an example of the symbol he used in the attached file, it looks like the diameter symbol but with a hexagon instead of a circle...

    measuring wall thickness

    how do i make a "non-bending" specialized micrometer that is at least 300 mm long and still light enough so a man can hold it while he is measuring?

    measuring wall thickness

    cant use what ajack1 suggested or mintjulep because the part is very long (about 400 mm ) and i need to measure the thickness threw all the length and this plier shaped devices are not accurate enough when they are long because they bend

    measuring wall thickness

    the client uses an XYZ machine to inspect it , the shape is opened so its not a problem to insert a measuring device inside , it looks like a an egg that was cut in half

    measuring wall thickness

    hi, i need to measure the wall thickness of a certain product , the product is made of ceramics and has an egg like shape which makes it very difficult to measure, in addition the wall thickness is not constant and varies along the profile . the average wall thickness is about 8.5 mm. i tried...

    small cylindrical parts grinding

    the machine were using is a small centerless grinding machine, its made out of two wheels- a grinding wheel and a regulating wheel that moves the parts, the parts move between the the two wheels , the accuracy level required for the diameter is +- 0.01 mm

    small cylindrical parts grinding

    I need to grind small cylindrical parts (diameter of about 1mm , length 3mm)made of hard steel and tried to do it with a small centerless grinding machine. But because the parts are so small they are flying everywhere and it’s impossible to get them between the two wheels of the machine. The...
