Or this one...
redfoxmachinery.com.au - Milling Machine - DM45
Not sure which one...
This one is about $600 more expensive. But has a larger workable area...
Looking at building a CNC mill and have been looking at this machine as a base...
M123 | HM-46 Mill Drill - Geared & Tilting Head | machineryhouse.com.au
What do you guys think?
Their is about three sizes of the RF-45 type machines. The lower price one has the exact same Y travel as the old RF-31 machines. The Z crank is on the right and it is about 100 pounds lighter than the other mill.
The DM-45 looks to be a re named RF-45 (this is good) with the longer travel and the Z handle on the left and the Z screw supported at the bottom of the column.
Both will be fine but you are paying a bit extra over their for all of them.
If you don't need the larger motor of the RF-45 type mills and you don't want to spend the extra $600 you might look at the Weiss 30LV mill. It is 500 pounds so it close to the lighter mill and is a fine machine with a higher speed spindle and a bit less money. Great hobby mill and it CNC well.
If you want max hogging ability spend the extra 600 and get the DM-45.
Thanks for all the info guys...
I have placed an order for this one: M123 | HM-46 Mill Drill - Geared & Tilting Head | machineryhouse.com.au
The other one's travel sizes were wrong!
So my next questions are:
What size motors should I be using? I would prefer to use servos AC or DC any links to good motors at a decent price would be great... Also the conrollers...
What diameter lead screws are you guys using? I have some 25mm and 20mm screws here if I can use any of them? Not sure if they will be too big.
Has anyone modeled one of these machines? Would love to buy a copy, just to save me the time in doing it myself...
Thanks for all your help!
i bought a hm-46 a couple of months ago, and am currently in the process of converting it. I am planning to use 1700 oz-in steppers on each access and 20mm ballscrews.
i am currently workign through modelling the whole mill in solidworks, before i start desiging motor mounts. Once i'm finished drawign, your welcome to a copy of the models if you wish, although i can't make any promises regarding a completion date. all XX-45 mills are slightly different, so unless someone has modelled up a hm-46 it won't be quite right.
my build thread is here (HM46 Conversion Build Thread), but theres not a lot in it yet as i'm still modelling. i think i'm going to focus on getting the x and y axis done first, then do z after.
Thanks for the info...
I have some brand new nema 35 1600oz steppers here if your interested? Was going to use them on another build but lost interest... PM me if your keen...
I think i will go servo in nema 23 format... And direct drive them...
Will keep an eye on your thread...
thanks! PM sent, although it's been buggy for me, so let me know if you don't get it.
Direct drive is definitely the way to go, and the whole reason i am going steppers. mucking around with timing belts seemed pointless when steppers are accurate and strong enought to direct drive.
Have you given much thought to ballscrews etc? The suppliers here in Aus tend to be a lot more expensive than overseas, from what i have found.
Just replied mate...
Looks like I will be ordering these:
3x Kelig 850oz/in servo motors
3x Gecko 320X's
Still need to work out what controller I want to use. Any suggestions?
Have some 2505 ballscrews left over from another build so will try and make these work. Have see how much room I have to play with.
