Thread: Newbie questions
So I'm a cnc newbie and I'd like some advice for a project I have in mind, any help would be really appreciated
I would like to engrave patterns and words / logos onto bicycle components. I am a vintage bike restorer and there was a fashion for this in the 70s -80s, though at that time it was done using a pantograph machine
Firstly I would like to know if you think this is possible to do with a cnc machine ? Some surfaces will be flat but others may have a slight curve e.g. Down the length of a seat post or along the stem (see attached picture) is it possible to engrave on a curve surface using a spring loaded tool or something similar?
Secondly I would like to know what kind of machine I should be looking at. It only needs to be small for such parts. Roughly 300 x 300 mm. I have had a look at some cheap Chinese ones on ebay but am aware they have mixed reviews. I'm no electronics expert so am not that confident in building one myself! ( though not totally averse to it ) the most important thing is it is accurate .
Budget wise I would like to keep it as low as possible, is around £600 realistic ?
Thanks in advance
Hi Peter, yes you can engrave on a curved surface with a sprung loaded spindel. Ithink that if you look in the showcase forum, somebody has made a really nice version. I have a very old dahlgren engraver with this facility, but have not yet had time to make a new controller for it. If you do get a machine, it will probably need a fairly high Z clearance to accommodate whatever fixtures you need to hold your material ( I know that goes without saying, but Iv'e said it anyway). Goodluck. G.
