I have one of the U-mark machines The Gem-RX. This has given us
perfect service for the past two years. Its in our retail shop and
my wife uses it to engrave customers jewellery and other stuff that
If you are going to get one, may I suggest you visit with the
reseller and arrange a full demonstration using your own materials.
I spent the whole day trialing the machine I eventually purchased, I
took a varoius items including the design for a pendant that I have
since made over 300 of with this machine.
I also have some extra software that allows me to scan and import
images and other fonts. I have engraved photographs and complicated
designs as well as using the machine as a lay-out tool for piercing
designs. It can also be used to lay out name pendants. It can
engrave a plate up to 6 inch square.
The standard tool it comes with is a diamond point to make the cheap
engraved items and I use this for the layout. It can also be used
with the spindle turning and a carbide tool that will cut as deep as
you wish to go (obviously the lines get wider, unless you use a
specially ground tool) If you look in my gallery on my web site the
Palladium/Topaz ring has shoulders engraved then cut out using the
machine. Also the Black Rhodium ‘V’ signet is engraved on the
machine. As are the copper woggles.
