    Literature- production process preparation for automation

    BrianPetersen/IRstuff/mcgyvr, Thank you for your replies to my question. The work I have completed (as the postgraduate research student) was done for one of the European companies. Because of the intricate operations, processes involves primarily manual manoeuvres that are greatly affected by...

    Looking for material- for a membrane

    Hi, I am looking for a material which could work as a membrane. Membrane of thickness in range 0.2mm-0.5mm. The membrane will be pushed (on depth of approx. 1mm) by array of little metal pins acting as a punch (each pin of diameter approx. 1mm and pins in array 3x3, pins very close to each...

    Selection of the guide rail for jig

    @MintJulep The jig will be working in the temperature of approx. (~)20degC. Fitting of the orange part- this is only concept drawing which will be converted into construction version later.

    Selection of the guide rail for jig

    @MikeHalloran, dvd, asimpson, Thank you for your opinions. I had myself some doubts regarding to alignment issue of the guiding bars in the construction arrangment presented on the drawing sent earlier. I have modified the construction, where there are two guiding rails on one side of the...

    Calculating length of wire in existing electromagnet

    Hello, I would like to ask for little help in calculating the length of wire in the existing electromagnet (bought from the shop). I know that bought electromagnet is for DC, 24[V], 1.3[A], 33[W]. Diameter of the wire is 0.52mm. I kindly ask for help. Thank you. Regards

    Electromagnet - source of power

    Dear All, I have constructed opposite poles electromagnet. The windings are made out of the enameled copper wire (~100m, ~300 loops, diam. 0.9mm). The core is made out of the recycled transformer plates (covered with translube varnish). The side plates are made out of the mild steel...

    Magnet for experiment

    Hi All, I am constructing opposite poles electromagnet. For the core I am going to use plates from the transformer (cut to required size on guillotine). I would like to cover exposed edges (after cutting on guillotine) of those plates with some laquier (to maintain effect of reduced...

    Selection of the material

    Thank you all for your replies. @1gibson - material would need be attracted by magnet (not magnetic itself). @EdStainless - The jig will not be loaded with any significant force. It will be working in room temperature (~20degC). From material strength point of view only the regular mild...

    Selection of the material

    Dear All, I would like to ask you kindly for the advice in the material selection for the jig that is under construction. The requirements for the material are as follows: - it has to be magnetic (the more the better), - non-corrosive, - machinable (milling operation), - low-abrasive...
