I've been looking into buying tabletop CNC machines lately ( I know you can make your own)
Have a look at this CNC machine
http://www.taigtools.com/cmill.html
The price tag is ~$2200.
Is that a normal price for it ? or perhaps there is a cheaper CNC with the same amount of accuracy?
-
That's about the normal price for a complete CNC Mill. A sherline will run you about $300 more, but it is a Sherline. I always recommend starting with a sherline lathe and building up from there. The sherline lathe has an attachment that turns it into a mill. Building up on the system a little bit over time costs a little more but it is easier to shell out $200 here and $100 there, than $2500 all at once.
Of course I still have not switched to CNC, I do everything by hand because it will always be more accurate than CNC.
-
By hand more accurate then CNC? I would think it was the other way around. Of course my construction skills suck so that might have something to do with it
-
The steppers from CNC are only accurate to a certain range, where as the handwheels can be more precise. Working under a 10X maginifying light helps ;D
-
Doing something by hand means with mechanical tools, not handwheels. There's one step from handwheels to CNCing :P
-
We use that exact CNC at work, (its the old and small one now but it still works) and its great for a first time user. We use solidworks and GCAM to run the machine. I don't know if anyone has ever used GCAM, but my mentor Justin Shumaker is the guy who made GCAM.
-
Yah I was thinking by hand meant with a hacksaw and a dremmel not a mill with hand wheels. I can see what you mean now.
-
Sorry, hung out with too many machinists in the Navy, if a computer does all the work it is CNC, otherwise it is by hand. Of course they also considered themselves artists, and seeing their work I could never disagree...

how about hacking an acra mill?

with a machine like a CNC , I would much rather buy it so that way I can get it serviced and then i get a warranty
