I am looking to purchase a benchtop CNC mill strictly serious prototyping stuff
Materials: Nylon, Derlin, Teflon, Derlin AF & aluminium
Precise vnc (turning, facing, parting, grooving) operations by sticking in the part into the spindle. Make small plastic gear boxes to get an estimate of how fast I can make precision parts using some techniques I have in mind (of course, I am a CNC newbee).
I prefer threading as well, but I am afraid I would be needing a servo based spindle instead of the standard dc motor spindle.... this is a different story altogether..
Diameter of parts -> 1/4 “ to about 2” … I can get them to the correct diameter before sticking them to an appropriate ER collet.
I live on the 2nd floor of an apartment; The machine MUST be under 200lb/ $2-4K. I am not interested in a DIY kind of stuff (no time). I am looking for something that is “out-of-the-box” turnkey solutions so that I can focus more on what I would like to do rather than how to make a CNC work.
I like CNC taigs that deepgroove and microproto offer, but I am not able to digest the fact that their $2XXX products don’t have ball screws…? Do deepgroove or microproto customize their taigs with ballscrews if I place a special order...? Money is not an issue for me unless we are talking about serious dollars. Does anyone have experiences with special orders at deepgroove and microproto?
Is there a way to attach ball screws to a taig; I hate backlash? Don’t these http://www.homeshopcnc.com/Ballscrews2.html fit a taig? if I purchase ball screws from here and attach them to a deepgroove taig, will it work without too many adjustments? Is there a way to configure the mach software as soon as we install ball screws with a different pitch? What are the steps I need to execute to make a taig ball screw enabled? I have read several prior posts on this topic, but I really don’t want to get into this install ball screw mess unless I don’t have a way out.
One school of thought is, why not go with townlabs TL518ER since I will be machining aluminum and plastics, but I am more lured toward the Taig popularity. Repeatability along with good accuracy are what I am looking for. Any suggestions are highly appreciated.
