RE: [CAD_CAM_EDM_DRO] new machinest and CNC

Hi, Jay:

You might want to cut out the middleman and consider rolling your own. You
didn't mention the work envelope size you need, but you might want to
consider either Sherline or Taig. Sherline uses a leadscrew for the carriage
and offers an optional set of threading gears while Taig uses a rack and
pinion arrangement. Some of the CNC G-Code interpreters (the program that
actually takes the drawing information and turns it into step and direction
pulses) support the G-33 code that allows a lathe to cut a thread.

The pieces you need are:

Machine tool
Mechanical coupling kit for motors to leadscrews
Motors - stepper or servo
Motor Driver
Computer
G-Code interpreter
DXF to G-Code Converter
CAD program that generates DXF format file

You can also choose a CAD/CAM package such as VectorCAD/CAM that provides
both the CAD and G-Code conversion services in one piece of software. If
you're on a budget, you can use Intellicad and ACE Converter, which are
free.

You might want to join the Sherline and Taig lists to better learn the
capabilities of their equipment. Some folks will also suggest the 7x10 asian
lathes (several vendors of basically the same product - Grizzly, MicroMark,
Harbor Freight, etc.) and there is a 7x10 list as well, but it seems that
these prouducts are not quite ready for good performance 'out of the box'
but require knowledge, tweaking and access to a machine shop (at least
that's what I inferred when I did my search about a year ago) which someone
like me does not have.

Hope this helps.

|Hi, I am just starting miniature machining and wish to purchase my
|equipment with CNC in mind. I worked with electronics for thirty
|years but do not know what components I need for a good CNC mill with
|roary table and CNC lathe with threading.
|
|I talked to FlashCut and Microkinetics but both want too much and
|offer no sales engineering.
|
|Any direction or advise is preatly appreciated.
|
|Meanwhile I will read the messages for information.
|Thanks,
|Jay Iski
