recomendations for a mill
« on: August 15, 2022, 05:59:04 PM »
Looking to buy a small mill to fab some part's.
I was going to order one from Grizzly tool for around $2500 but they are on backorder.
Been searching all day and all I have found are the cheap low powered china mill's. Less the 1/2 HP or the $13,000+ one's.
I would like at least one with 3/4 HP or more and non plastic gear's.
Anybody have any recomendation's
I would consider a china mill but would like some real review's on the quality of any suggested.

I have had my Grizzly 3n1 (drill,mill,lathe) for 20 years and been pretty happy with it. A budy of mine has a Smithy 3n1, it may be a touch better than the grizzly. You may want to check them out.

Get a used Bridgeport or that type of machine, they run 1 - 3 hp. A BP an be had used for $1500 - $3000, in good shape. You almost can't wear them out and can use them, standing up, straight. They weight about 2000 lb but, will fit in a garage.

The smaller mills will only frustrate you. It's much better to have more mill than you need, than be undersized, just a little. They are also, extremely versatile.

Tooling is also, bountiful and cheap.

I bought my Lagun (Spanish made BP type), new, in '82 and 40 years later, it's still is almost as good as when I bought it.

If you have the space, I'd agree with Frank, get an old Bridgeport or equivalent.  Wait for an auction and you can get one for a good price; there are some local machine auction houses around my location where those types of machines come up regularly.  A lot of times a CNC shop will be going out of business, and still have one or two manual mills at their facility that will also be sold with the rest of their equipment.

Space is kind of a problem but I can make room if I park a car outside.
I have went to 3 auction's in the last year where there was a bridgeport mill for bid but I found out the dealer's from Dallas and Houston are going to them and when you bid they will just bid $50 more then your bid untill you give up.
I went to some site's who resell but the shipping cost are more then the mill and I would have to unload it myself as I have no help.
I was looking on the web and found a company called Sureline that make's tabletop model's here in the USA. Never heard of them before but the review's are great. some of the user's have been using the same mill  from the 70's with no problem's.
I am only going to be fabing small part's and not doing any head rebuilding or the bigger stuff so don't need a big mill now but would prefer a bigger one because of what I might decide to do in the future.
Thanks
For the suggestions.

I have a square column G0519 Grizzly that has served me very well.  It ain't a Bridgeport, but most of the little machine shops died out way long ago so finding a B-port locally has been - nah.  Last one I saw here a couple of years ago they wanted about $2K and it had been sitting outside.  Or - they are huge 3 phase 440V oil field grade/heavy industry stuff.  I've seen some big CNC equipment go dirt cheap.

I've had this G0519 quite a while - 1HP 3 phase with a converter.  I'm fixing to mount a 3 axis DRO on it, why I haven't done that I don't know LOL.  Oh - paying for the new TIG welder that's why.  The square column keeps the Z axis in line if you have to move the head for say, drilling and then guiding a tap.  I'm eyeballing how to get a 180 lb Dart block on the table right now so I can drill/tap some 10-24 holes for a valley cover plate.

Craft will apparently be auctioning off old equipment...

That is about what I tried to order from Grizzly but everything they have is on backorder except the $700 machine.
I have had to much experence with how back order's are working now to order and then wait.
It is a shame that Craft is out of business I really feel bad for them.

     I agree whole heartedly with this advise.   :)

     Avoid the cheap-import stuff (Grizzly?  :P ), as this will in the end prove to be just that!   ;)

     I wouldn't say you can't, but, you can't buy to big a unit (that is, and have it fit in your garage that is!  ::) ) that is unless your solely taking up watch making; so in trying to determine just how big a unit you'll need, figure out what table surface area and traverse distance you 'think' you'll need and multiply this by at least one and one-half times, if not by two, and I assure one day it'll still prove not big enough!   :o

     We have two Bridge-Port brand 'knee-mills' ("table-top" units are to small for anything other than 'tinkering'  ::) ) in our shop, nice units, one from an equipment dealer, the other at an auction. 

     As far as self-moving them, at perhaps a couple thousand pounds, if you don't have the proper equipment (like I do!  8) ) just rent the necessary equipment to move it safely, a truck and or trailer (now might be when it pays to have friends!  ;D ), a fork-lift and or pallet-jack; they're not that expensive (at least not where I'm at).  And though not difficult, be sure to understand the proper procedure in handling them (most importantly: center of gravity!)   :)

     Scott.

Thanks for the advice. I really don't need a big mill for what I am doing.
I build my own sporting arm's.
As to the transport of a bigger mill I do have a rollback and a good trailor however I sold my forklift and pallet jack's with my building when I retired from manfacturing in 2004.
If I had a big mill I know what would happen, I would start to think of new thing's to do with it and would never have any relaxing time to myself. [lol]

Check with Precision Matthews - they may have something in that size range that you need.  Like a PM-940M

My Grizzly has been in use since June of 2009 and I haven't had a single issue with it.  It's accurate enough for most things.  I might not try to surface a V8 cylinder head with it because it doesn't have that kind of power, but it's repaired transmission cases, made parts, drilled distributor shafts and what not.  Latest was milling a big sheet of .250 aluminum plate for the Dart valley cover.  It has a 9x32 table with plenty of X and Y for most things.  The only real shortcoming that I can think of is that it doesn't spin slow enough to be good for maybe cutting seats in a head.  I can turn down the hertz on the drive but closing in on 40 hz the motor starts to chatter.  It'll punch a 1" hole in steel plate no problem.  It has well paid for it's self.  Same with my Enco 12x36 and my HF 9x20 lathe.  Sure the Enco ain't a Lebond but the spindle still spins at .000x TIR. 



The only small shop size mill I see for sale nearby here is a 9x50 Acra that's listed at $10,500.  Jet sells an 8x36 that looks nice but runs close to $8K.
This is for sure your "low price leader" but these have a really good following and lots of data about modifications, improvements and such all over the web

I have been in the market for a new mill as well recently, and as a primer, I took an advanced manual machining course at a local Tech School this winter to refresh some of my skills as it had been 15 yrs since I was in school, and the job has become much more desk orientated.....  First day the instructor points to the row of Jet lathes and states "J E T = Junk", next the 2 Grizzly mills, "Grizzly = Garbage"  Being that I now live in Springfield, that soured me on Grizzly, even though it is still fun to walk through their scratch and dent show room from time to time and pick up some deals.

I will 2nd Falcon67's suggestion of Precision Matthews. 

Also, Watch some of Abom79's videos.  The guy is an expert machinist and generally seems to have pretty good advice on equipment.

Thanks for the link.
I think I like the PM mill's. I looked at the PM-25mv at $2300 but when I started adding on the option's it got close to $4000.
That's a little more then I wanted to spend as I wanted to keep the cost under $3000 if possible.
The PM-940-m isn't available any more ar at least they did not have a price on it on their web page.

I can say I have not seen much of Grizzly since the mid 2000s.  Not a lot of people buying their metal work machines, other than maybe the lathes.  If I were to buy another, PM would be my first look these days.  Love to have a 9x49 knee mill but $$$$ and space.  However, if I found a B-port Series 1 in good shape for $2500~3K, I'd probably find the room LOL!
