    Question Flat parts Vibratory Tumbling or Cetrifugal Disc Finishing?

    Hi,

    I make flat Sterling Silver pendants and charms. I have them either lost wax cast, laser cut or die stamped/blanked. They are quite small (10-20mm) and 0.8mm to 1.2mm thick. They are all totally flat. I need a perfect Mirror finish or sometimes a nice smooth pre-plate finish.

    I am looking to buy a small finishing machine and was wondering if anyone knows which would be the best type of machine for my needs. I am concidering either a vibratory tumbler with speed adjustment and flow thru, or a Centrifugal Disc Finisher(Otec Eco Maxi Wet, used on a slow speed) with speed adjustment and flow thru.

    I will be using plastic medium and plastic fine abrasive cones with vibro liquid as they are softer than ceramic media, then green dry pre-loaded buff media.


    Anyone know which would be the best type of machine for flat parts? Vibratory or Centrifugal Disc?

    Thanks,
    Hannah

    Dear Hannah,

    Otec Eco Maxi suitable for small and medium-size parts (like jewellery)
    You can use these parts in this machine
    We have Otec eco maxi wet (https://www.inovatecmachinery.com/product/otec-eco-maxi)

    If you have a smaller amount, just acquire a small desktop vibratory tumbler
    Although the finishing time would be longer, the surface finishing result will be perfect.

    Earnest
