Budget changed, now what..?

[Rekd]

It's taken a year to convince my wife to let me get a mill. My goal is to get a decent manual mini mill that I can convert to full 3 axis CNC as money permits.

I was first limited to $300-$400 for the mill. Seems the wifey's been stockpiling money, and graciously said "If you have to spend a couple hundred more to get something you can use better, do it".

(She said the same thing about buying my last truck, and didn't faint when I came home with a GMC 2500 HD DD 4x4, so here we go...)

At first I was looking at the Grizzly/Homier mini mills for around $400-$500. With the budged increase, I figured I could possibly get that mill and a good start on the conversion.

But now I'm thinking the TAIG Micro Mill or Sherline 5000/5100 mills for around $700 would likely result in a better CNC when all is said and done. Is this true?

Are the Taig/Sherline mill's good for manual stuff? They seem to be a bit less rigid than the Grizzly/Homier types, just from looking at the pictures.

Also, what might I be looking at money wise to convert the Taig/Sherline to 3 axis CNC?

I'm planning on ordering by the end of the week, and am really excited. But I don't want to get all giddy and get the wrong stuff.

How about one of these- http://www.imsrv.com/deskcnc/bench_top_cnc_systems.htm

Looks like just a kit alone for 3 axis will be around $700 to $900 plus the machine. They look like good systems, but I prolly won't be able to do it all at once due to funding issues.

If you go the Sherline or Taig route you must check out Zylotec, they have ready to roll cnc kits from 325.00, specifically designed for Sherline/Taig. Good luck and have fun, its the best hobby Ive ever found.

Rek'd There is a mill sherline mill for sale in the cnczone classified area you might be intrested in?

Not have ever used either of the mills I kinda feel unqualified to give an opinion. Hhaaa, but it's never stopped me before.

I like the fit and finish of the sherline/taig.

I like the apparent increased stiffness of the Grizzly/Homier.

The way I approached my buying decision was to think about what I would keep from the original machine after the CNC conversion. Basically that is only the major castings. All the peripheral "stuff" was removed. So if sherline/taig has nicer screws, cranks, dials, prettier paint or similar it doesn't matter cause it's gone.

Second to the casting quality would be drive motor quality and the method of delivering the power. Belts (round, flat or Vee) or gears. And the speed of the spindle, is it appropriate for the material you will be ruining, oops, no, I meant finessing

Spindle taper, available tooling, costs?

Now if you wont be replacing the screws with ball screws you will have to consider the quality there.

What is nice is you can get replacement items for all four mills and there is a wealth of info available throughout the internet.

You are in one of the best stages of converting a mill to CNC, "lookin through the wish book".

I have heard good things about the Taig I have a micro mill converted to cnc and I also just got a Proxxon MF70 off ebay for 200 that I will be converting to cnc for engraving small parts. I like the micro mill but it has some limitations and other things you must work around Z axis can be a headache. I have heard from a friend the Taig moves very smooth in all axis and you can move it with one finger in all axis. I don't have one just what I have heard. Good luck.

Rekd, youll likely spend what you paid for the machine in tooling(cheaper machines anyway)
If you were to convert a mini mill, full ballscrew and all, it would eat a sherline alive.

I have used a sherline a while back and Ill tell you that it wasnt necessarily a good experience.
I have a video of my mini mill but I havent gotten it uploaded, PM me and Ill show you how to download it off me, will be uploaded somewhere soon.

Thanks all for the info. (JFettig, I d/l the avi and it was audio only)

I will likely be ordering the TAIG micro mill. Looks like a fairly tough and smooth machine.

[JFettig]

oh, Youll need the newer divx codec for that movie,

how much will a taig machine cost overall? and what kind of spindle taper does it have?


Jon

[Rekd]

The 2018s (has the machine, a vise and a couple collets), runs $684.00. The taper is a 15° (30° included) Taig Micromill

Looking into the codecs, thanks!

Rek'd I had a Taig mill for a year or so, converted to CNC with a flashcut stepper system. The mill is put together very well, and everything works as advertised, but the thing is tiny, and does not have much HP, 1/4 hp last time I looked for their CNC model. Expect programs to take a long time because of speed feed limitations, and you'll have to stand there with some sort of mister, or coolant. It'll be a mess on the floor.

I'd hope you could actually see one in action before you spend the money so you know what it and is not capable of.

BTW if you do decide to go with it, I have a Flashcut 3 axis stepper drive box that you can have if you want it, that'll save you a few bones at least if you decide to use steppers.
